creating jasper sub-report using iReport

creating a sub-report example with Jasper

Pre-requisite: I assume that you know how to create normal reports using iReport GUI tool also basic knowledge of database, sql with MySql.

before we start with actual creating of report lets understand the database that we require.
following is the table structure that we require.

I have taken the sample database that comes with iReport hsqldb, you can use that directly also.










following is that data within each table.

I have restricted data to minimum to show here if you fire the same query in iReport you can see all data.














so basically it shows the billing information for each transaction taken place, master table is document and its detail table is positions.

lets now create a sub report first which we need to include in the main report for every transaction.
so open iReport tool
1. file>> new... click on "Launch Report Wizard"

2. enter report name and its location where it will save report on local machine
name: sub-rpt-det
location: C:\data\mytest
file: C:\data\mytest\sub-rpt-det.jrxml

click on next,

3. if you are using hsqldb / mysql databse as a datasouce choose appropriately.
paste following query in the tab
select * from positions
where documentid=0
order by positionno
later, we will be replacing the documentid value with the actual parameter passed from the master report.
click next>>

4. select all fields shown in the left side of fields combo
click next>> next >> finish

5. set title, page header, summery band height as 0 (zero)

6. add the fields to report detail section

7. add fields column labels in the column header

8 now goto report inspector >> expand variables >> right click on variables>> select "Add Variable"
9. check the following variable1 properties for the variable that just created. modify them appropriately














10. similarly create another variable named tot check out its properties as below














11. Place the field "cost" in detail section at end and "tot" field in column footer along with label (see below)

12. add a "Rectangle" box in the column header and move it to back, add a background color as gray

13. add a "line" the column footer.

your report will look like as below





14. try to click on preview button and check if its generating output

15. go to report inspector>> expand parameters>> right click >> "Add Parameter"
add a parameter named "m_docid" change its parameter class as "Integer"

16. click on db tool button is next to preview button
replace the query parameter from (zero) 0 to $P{m_docid} so your query will look like as below

select * from positions
where documentid=$P{m_docid}
order by positionno
with this your sub report is complete now lets create a master report.

1. file>> new...

2. click on button "Launch Report Wizard"

3. enter report name as "mst_rpt"
name: mst_rpt
location: C:\data\mytest
file: C:\data\mytest\mst_rpt.jrxml

click on next,

4. if you are using hsqldb / mysql databse as a datasouce choose appropriately.
paste following query in the tab
select d.*, a.* from document d
left join address a on a.id= d.addressid
order by task
click next>>

5. select all fields shown in the left side of fields combo
click next>> next >> finish

6. select Palette>> report element>> sub report
drag it to the detail section. subreport wizard will appear on screen

a. select option use existing report and browse and select the sub report that we had created.
C:\data\mytest\sub-rpt-det.jrxml
click next>>

b. select first option "use the same connection used to fill the master report"
click next>>

c. it will show paramters created in sub report "m_docid" which we need to map with the master report field so we will be passing our document table's id filed here, click on expression drop down combo you will find all parameters, fields and variables that are defined in master report. choose "id" field from it.
click next>>

d. select the first option of subreport expression as "store the directory name in a parameter"
click FINISH

so your master report created with its sub report and other fields added in the details band will be seen as below










click on subreport and check its properties as below












note the parameters says that one parameter defined click on its button and see that it should show the m_docid as the parameter that we are passing to sub report.

here is the way to pass parameters to sub-report and to get value from sub-report
note that when you pass any value to sub report, that value may be parameter/field/variable defined in main report. you have to take special care for variable field of main report that it should have defined and has some value. please see below image how to pass
define one parameter in sub-report that will accept value from main report.
make sure that data type of sub-report parameter and main report parameter/field/variable should be same/compatible. here I have defined m_docid which will take value from main report.


similarly now when you have to define a variable that returns a value from sub report note that
1. values should come from sub-report variables, and place holder in main report also should be a variable.
2. variable defined in main report will get populated only after sub-report is totally generated, so it has to be placed after sub report defined.
please have a look how to get value from sub report.
1. I have defined "AValueFromSubRep" variable in main report
2. then I am mapping this variable to the sub report variable "totcost"


see how its get written in jrxml as below.
<subreport>
    <reportelement height="34" width="555" x="0" y="43">
    <subreportparameter name="m_docid">
     <subreportparameterexpression></subreportparameterexpression>
    </subreportparameter>
    <connectionexpression></connectionexpression>
    <returnvalue subreportvariable="totcost" tovariable="AValueFromSubRep">
    <subreportexpression class="java.lang.String"></subreportexpression>
   </returnvalue></reportelement>
</subreport>

now save the report and click on preview it will show the report with its sub report details as below
























thats how you will do a subreport.

  1. Hello ..
    thanks for this nice tutorial, really helped me.
    But I've two questions:

    1- When previewing my report, I see a large gap between details & column-footer, how to fix this?

    2- I created a subreport with charts, then included it in the master report (with tables in it's details band). The output is generating the chart repeatedly over 30 pages without full display of the original table (i.e. each row displayed per page), any idea how to display first page only of the subreport?

    Thanks

    ReplyDelete
  2. 1. there are 2 things to avoid this first don't leave any gaps in your bottom side of detail band and fields placed. secondly there is a report level property "Float column footer" checked it to have column footer come exactly below your detail band.

    2. you need to place your subreport in summery band to generate chart only once after your main report generate table. if you want your chart to appear first before table put it in page title band.

    ReplyDelete
  3. Thanks for your help.
    I've added the subreport in summary band, charts are no longer repeated,
    but the summary band appears in the next page.

    Can i configure it to be displayed in the main page?

    Thank you,

    ReplyDelete
  4. it depends on how much data it generated on that page. if it has no space then it will move chart on next page only.
    Also check if you have checked report property "summery on new page".

  8. hi,i have a report with five sub reports..how can i adjust them so that there wont be overlapping of reports? and iam getting main report balnk...i want to move the data up how can i do it?as u said to check the property of summery on new page it is not enabled..and what is difference b/w detail and summary?can we keep subreports in either of them?please do reply...thank you..

    1. Hi,
      1. how can i adjust them so that there wont be overlapping of reports?
      >> when you create sub reports and add it in main report, it depends on the order how you place them in main report. execution will take one after another as you have placed. Also it matters where have you placed in detail or footer or summery etc.

      2. iam getting main report balnk
      >> this could be
      a. probably you have left detail blank with some height.
      b. if you have no data in main report you should keep height of all other bands to 0 (ZERO) to avoid blank spaces.
      c. also when you place sub reports you make sure you are not leaving spaces in between two sub reports
      d. also inside of sub report there should be only detail section and no header and footer (check my example point 5, 13)

      what is difference b/w detail and summary?can we keep subreports in either of them?
      >> in general details band gets repeted no. of times the rows that you have in report and summery only once and end of report. with respect to report having sub report in it. It really depends on your design of report most of time sub report will have their own data (detail) and main report is just used as container to club all sub report so we keep sub report in end section.

      hope these points clear your doubts. if there is anything please feel free to ask

  9. hi sir,thanks for the quick reply...
    1)as i said that iam having 4 subreports.i kept them in main report by creating 4 detail bands (each subreport in separate detail band)is it a correct way?and
    2)when we make an existing report as subreport of other , url should be till jrxml or .jasper?
    3)how many subreports can we have..and is it compulsary that we hav to make a subreport when it is very necessary or we can just take a subreport so as to decrease our main report query..?
    4) for all the above cases what would be the performance effect?

    hope these are not many questions..thanks in advance...reply for my previous query was really helpful..thankyou...

    1. Hey Hi,
      1. Well you need only one single band in your main report
      and in one detial band you can keep all your 4 sub report one below another.
      2. while including subreport in main you can use any of approach. but more useful is jasper because it works faster as report is already complied
      3. There is no limitation as such how many you can add... it depends on your report weight and generation time that it takes, thats barealble to you.
      4. as I said above it depends, I had example of main report having 8 sub reports and 3 subreports having another 3 sub report in it. and it works pretty fast. acceptable for my client.

    i also wanted to ask u abt fonts,i changed pdf font to arial in xml & i am not getting pdf file...so when i gone through net i got to know abt .ttf files where do we get these..to set a classpath for font...and what r the fonts that support printing of reports...and in ireport text preview is not working...can we take print of pdf as well as text files? how to export our report as text file?
    thanks again for ur reply....

    1. Hi Again,
      Well Thanks,
      nice to hear that it worked fine.
      normally you find ttf fonts in your c:/windows/font directory. but assume if your reports are running from unix env. then its a diff case.
      I have not much checked about changing fonts other than what are normally available.

      is your reports are only text?
      people genearally use rich text to generate text report. I don't know if jasper provide only text output.
      but if your report is columner and you want only text output then you can choose CSV format. and you can open in excel or normal text file.

      hope you get things.

  12. hi sir,i have a problem when i keep all my subreports one by one in detail band all the reports are overlapping..if i keep them in summary then i have to set it like givivg gaps between subreports...so if there will be more data for first subreport then it overlaps with second sub report how to remove it?
    and in crosstab if complete row or column is null that is no value i want it to show 0 but it doesnot give that row or column at all...what to do?
    thanks...plz reply

    1. Hi Sorry,
      I had already posted but it did not applied so writing again,
      As I had mentioned to keep subreports in footer or summery part based on your requirement. becase summery gets executed only once at report end. and if your main report has some data and sub report requires parameters and need to prind filter data for each row of main report then it make sence to keep sub report in detail section.
      well, the data length of subreport do not matter and it do not overlap with other sub report, unless you have given its position type "Fix relative to Top"
      if you keep "float" then it will cause you problem of overlapping.

      for your second question there are couple of things to check.

      check for your every field in the row or column
      . "remove line when blank " is not selected
      . "blank when null" is not selected
      . "print when expression " you must do a check if value is null then print 0 "

      Other alternate is from your query/dataset make sure that for null field you are passing default to 0 value.

      I hope this will help you.

  16. Hi,

    I am facing one issue in subreport is he records in the subreport gets distributed in two pages when there are more records in subreport to display and in my case I don't have fixed size of records included in subreport so there may be case where one report will have only 1 or 2 records in the sub reports and there second main record will have 20 records included in the subreport

    I want my report to display the record in the page if the whole record can be fit in the same page else it should be displayed in the next page.

    Please help me if there is any property need to be set.

    Replies
    1. Hi Shraddha,
      If I understand you correctly you just want that report to print its details in page only if it fits otherwise move on to next page.
      Yes ? if so then yes Jasperreports provides such feature it is called "Split allowed" -> this one is now depricated and replaced by "Split Type" depending on the version that are you using it will be available
      this property is available for the band you need to apply/change this property for your master report detail band.
      you need to change
      split allowed -> unchecked
      Split type -> prevent
      and Jasper report will take care of rest.

      hope this helps. do comment back.
      good luck.

  18. Hrllo Sir,

    I Have one more issue that is when my record in the subreport is too big to fit in single page it carry forwards to another page and I get Total on both the pages where as I only need the Total at the last for all the items in that particular record.

    And another thing is when the subreport get overflow and the items are carry forwarded to the new page at this point my design i.e. border and squarebox does not show in the next page. In the Next page the subrport Items are shown without design

    ReplyDelete
  19. If I keep the sub report as it is to display in two pages as my records in subreport are more than 60. So I think it can't fit in one page but than I want to display the TOTAL only once in the end i.e. the second page where finally the subreport will complete. Currently its showing me on both the pages as I have added it in pageFooter band...Please help me its urgent as Project is going in production

  20. hi sir i have report which is having 3 subreports ,but i need to call only one subreport and all 3 subreports have same parameters.so i have fixed a value for each report so that main report can differentiate to call particular report...can we do like this?
    please help...thanks in advance..

    ReplyDelete
    Replies
    1. normally every object has "print when expression". so for your subreport also has this you can place a specific condition which will be true for one report at a time to make only one sub report to run rest.
      2nd solution would be for each sub report make the query fail on condition so that only one sub report can fetch data and other 2 subreport query fails and for each sub report main properties you set "when no data" expression "no page/no detail" so it will not gernerate any row for same.

      i hope you get this...

      good luck... and feel free to ask

    should we change default expression in jrxmls also?

    if we have to change how and where we have to change it?

    initially i stored my jrxmls&.jasper in jasperreports folder in /root/JasperReports.

    please do help...its really important and urgent....
    thanks in advance...


    instead of giving like this can we have dynamic saving..because if i want to store the folder some where else then i have to change this line in all files!!

    1. hello please let me know what kind of application it is ?
      if it is web based then it has to be in your web-inf/classes
      folder. or if its a stand alone application then you need to specify the classpath during application startup.
      additionally even if your web application if you have any path outside of your application then you can make it globally available by putting in server lib folder or either specify server startup parameters.

      i did not get what you mean by default expression means?

      if you are going to change jrxml during run time of program then it make sense to generate jasper files dynamically.

    1. you mean you use stand alone application?.
      a way could be to configure your path as a property in a file or store in database. load it at run time if it get changed then then it will not affect your code because you will change path in database or in file. but your calling machanism is intact. eg.
      assume you read it from property file as below
      property file (app.properties)
      -----------------
      report.path=/root/mno/xyz

      code
      ------
      properties.load(new FileInputStream("app.properties"));

      String path = properties.get("report.path");

      URL jasperResURL = this.getClass().getResource(path +"/myreport.jasper");
      JasperReport jasperReport = (JasperReport) JRLoader.loadObject(jasperResURL);

    1. it basically depend on application style... I never used jasper viewer to integrate with application. but still i think that can be sufficient. or you can simply write a export servlet to export. both servlet and viewer support facility to export in different supported format. location would be on clients machine who invoke servlet or report.
      my humble request to just search on net for example to export report. as I don't have setup at moment to come up with example to show...sorry for that

    3. it depends on your applcation or your need if you need to complie jrxml everytime then you need to keep jrxml or otherwise you can simply keep only jasper files for faster processing.

      normally jrxml forms the part of your web content so it should be under your context root so that classloader could able to find it.

    1. there is a way you define a variable.!
      and use expression to count on details band... unfortunatly i can not show it now. but if you explore you can get it.
      there are expression available to sum or count etc. so you need to put field whose value you want to sum and there is also a expression to reset the variable which you need to set at end of report or group etc.

      pls explore.

    1. Hi Dondell,
      Thanks for appriciating, well it may be possible, provided you make sure that your total of column of 1 is process before calling sub report and is displayed earlier. it is possible to pass variables to sub report.

      hold value of column total in variable and pass to subreport as parameter

    1. There are many ways, you can fix, first and most do you want to round it off or not? if yes then what it is doing is correct if not then try to fix from database from where you are getting values else, try to use formatter, or also try math.slab. and if nothing works just get value in string and trim it to 2 places after dot. hope you get it.

    1. Hi, i could only think that try to check the parameter or field datatypes are set properly or not this may cause due to it. seems that it is reading like string but trying to read as bigdecimal. if both datatypes match (database and report filed) then it will work proper.

      Goodluck,
      Rajendra

    2. hi sir,what you said is right ..i changed all types to integer its working.but i have a query(which contains sub queries) which returns 7-8 values(fields) for 5 rows.it is working fine.but in some cases a field in a row will give more than one value, how to get like that means 5 fields are normal with one value but 3 fields will give 2 values each.i used group_concat ,so its showing values but at ending i have to add complete column .so please tell me what to do...waiting for your reply..

      Delete
    3. forgot to mention as its subquery if it gives me more than one value it shows me sub query returning more than one value...hence i used groupconcat.

      Delete
    4. Hey Good to know that it worked for you, but I did not get your question, what you mean by add complete column at end? and where have you used gourpconcat? at database level? or in report?

      Delete
    5. i'm using it in ireport ...& adding complete column is from top to bottom i have 5 values for one column and i have to show their sum at ending ..down like addition

    1. Hi It is possible,
      follow below steps
      1. create a variable ret_value_xx in main report
      2. set evaluation time as band ( so su report should able to pass value correctly)
      3. define variable in sub report sub_rpt_xx
      4. in main report again go to subreprot properties
      5. you will find property return values
      6. add value there subreport variable= sub_rpt_xx and destinationvariable= ret_value_xx
      7 or (instead of step 6 directly modify from source insert below line in your subreport tag after connextionExpresison

      8. done

      I hope this will help you,
      unfortunately i dont have setup here so cant explain in more detail

    1. Hi Please read end of my tutorial I have explained how to return value from sub report, but there is pre conditions I place it here --
      when you have to define a variable that returns a value from sub report note that
      1. values should come from sub-report variables, and place holder in main report also should be a variable.
      2. variable defined in main report will get populated only after sub-report is totally generated, so it has to be placed after sub report defined.

      I hope if you follow same it will work otherwise please expalin in detail.

  39. Hi ,

    Same as you explained I have a variable defined in my subreport- "myvariable" with value 12345 .I assigned the same to my main report variable named "Temp" using the return property .And I have placed my subreport element in detail band and Temp variable in page footer band of my main report.I have tried out the calculation types "System"/"Nothing and evaluation time to Band but nothing worked .Still My main report shows null value for the variable "Temp".

    1. Hi Kayal, your procedure looks ok.
      does it give any error on generation? if not means it is not yet defined as return value in your sub report, try to verify same by looking at source code in jrxml in subreport tag for following as shown in my example



      just once again verify following.
      -- sub report
      define variable (myvariable)
      variable class = string
      variable expression = 1234

      -- main report
      1. define variable temp
      variable class = string
      2. add subreport>>properties>return values
      subreport variable = myvariable
      destination variable = temp
      3. add variable to page footer
      texfield in page footer should also be of type string

      hope this works.

    i have some staitc text as a heading of subreport-1 ,in detail-2 i have some paragraph to print and in detail-3 band i have 2nd subreport-2 , But when i am compling it and getting pdf, i am getting the subreport-1 data in detail-3 band ...

  43. Hi,
    I have made a report for invoice printing.

    Problem 1: Detail band should extend or should have a fixed height even if it has only one row, it should end just before the group footer where the subreport is kept.

    Problem 2: Have kept subreport on the group footer and set it's footer position properties to Force at bottom and it's working fine when previewing in jasper but when i compile & run the report on live environment it shows the subreport on the middle of the page right after the detail part.

    Thank You

  44. I want break a4 page into two exactly two part invoice bill one as original and one as duplicate plz help me out from this

    ReplyDelete
    Replies
    1. enven though you give page break it will not evenly cut your page, becauase it varies with your detail band number of rows it generates, unless you are sure you have fixed row format.
      well but solution would be define your invoice format in sub report and use sub report twice in main report with pagebreak.

    1. Hi Siva,
      Are you sure your database query is not returning duplicate records?
      please make sure your query has proper results as expected.
      I don't think it would be possible anything from jasper side.
