Deploying reports with subreports

[rajeevt]

I am trying to deploy a jasperreport with a subreport in Tomcat environment. The normal reports without subreport work perfectly. However, the master report has a SUBREPORT_DIR parameter from where it should pickup the subreport.jasper. What is the value I should be passing to this parameter? I have tried various options but always get an exception saying couldn't load the object from the directory. The syntax I use is as below:

 

private static final String PREFIX = "/WEB-INF/reports/";

 

private static final String SUFFIX = ".jasper";

 

externalContext econtext = getExternalContext();

 

InputStream stream = econtext.getResourceAsStream(PREFIX + name + SUFFIX);

JasperPrint jasperPrint = null;

 

jasperPrint = JasperFillManager.fillReport(stream, params, conn);

I have managed to solve it. I had to pass ../reports in my SUBREPORTS_DIR path to make it work. Any absolute path gave problem.

Any idea how this is done from the report itself? Not from code.

 

The SUBREPORT_DIR must have certain value? Can it be passed as a parameter from Jasperserver? if yes how?

Forget the parameter SUBREPORTS_DIR, and use as expression for your subreport something like:

 

"repo:yourReport"

 

where yourReport is the name of the resource containing the jrxml of your subreport: infact the best wat to use subreports in JS is to load the subreport jrxml as resoure in your report unit and refer it by resource name.

Will "repo:yourReport" be affected somehow by placement within the repository? i.e. folders and subfolders?

I am struggling with using a URL to call a parent report containing a subreport. I have a servlet engine on a tomcat server which will send a .jasper file to a browser. The URL calls the .jasper subreport with no error, but when calling the parent report I get a can't find the (subreport name) file error.

 

I've tried various path combinations, and I've tried your "repo:reportName" (see image below), but none have worked. Do you have any guidance you can give me on how to get the parent report to properly call the subreport from a tomcat server?
