sub report example

[rida_10]

HI ALL,,, 

ihave been working on ireport designer 3.0,  to develop sub reports

and i used the $R{subreports.folder} resource bundle to refer to the location for my sub report  as such:

 

$R{subreports.folder}  + java.io.File.separator + "Sub_TotalSummary.jasper"

 

where subreports.folder property refers to a location on the hard disk :

subreports.folder=D:/my-reports/build/3.0.0 (all .jasper reports are generated in this directory)

so where ever we want to run the report we only  change the value of subreports.folder 

 

THE QUESTION IS HOW TO REFER TO SUB REPORTS WHEN REPORTS ARE RUN FROM JASPER SERVER NOT FROM AN ORDINARY JAVA APPLICATION.

 

THANK YOU

RIDA

Hi, I usually save the subreport in the same directory of master report and I'm using

$ P{SUBREPORT_DIRECTORY} + “subreport_name.jasper†as subreport exression.

When I create the report unit on JasperServer I put the subreport under "Resources" of the report unit. Hope to be usefull ...

Hi Rida,

 

You need to change the subreports.folder value as "repo:" and upload your subreport as a resource to the same report. This will solve your issue. For example: your subreport location should be "repo:Sub_TotalSummary.jasper".

Hi Nitin

your proposed way resulted in an exception:

Error loading object from URL : repo:/Reports/Services/IPT/Sub_TotalSummary.jasper

as i run the report, pioppogatto's way worked,

Best regards

Hi Rida,

I sow you solved your problem with my solution! I'm writing "my solution" for everybody else that see this thread ....

1) In iReport you can develop your master report with one ore more subreports. It's important to save the path of the directory of the subreport not as an absolute path (like C:\\my_jasper\\subreport.jasper) but using a parameter (if you use the wizard when you are designing you subreport in your master one, you have to check the right option, and the subreport path will be (Attachment 1):

$P{SUBREPORT_DIR} + "name_of_subreport.jasper"

 

2) When you will add the Report Unit on your JasperServer you will be asked the proposed expression for you subreport (Attachment 2). Click on "Continue" button to confirm the expression "repo:name_of_subreport.jrxml"

With such procedure JaspeServer will automacitally copy your subreport under the Resources directory of your report unit (Attachment 3)

Hope this should be usefull for everyboy.
Bye
