Subreport path

[dabor]

Hi to all.

I'm making a simple report-subreport hierarchy. I insert the subreport (existing subreport.jasper file) into report.jasper, they are in the same folder. I set the subreport expression to "subreport.jasper" as they are in the same folder.

I recompile both report and subreport and run the report. It all works well.

But the problem is that this doesn't work from the java desktop application. I get the exception:

Could not load object from location : subreport.jasper

I also tried to add the report/subreport folder to the classpath, but that didn't help either.

 

So, how to add subreports so that they work from the application too? So far I didn't find anything useful, even searching this forum. Can anyone help me out, please? I desperately need help! Any hint or pointer would be greatly appreciated!

Thanks alot!

when you select put the subreport in report, the program give 2 option for the path of subreport.

relative or pass a path for parameter

You are select pass the path for parameter.

You must create a parameter with the path of subreport.

the name of this parameter you can see in wiew -> parameter of report

Thanks for a quick reply.

 

And how do I get reports path for (deployed) java application? The subreport is in the same folder as a main report, if that helps.

 

Thanks in advance.

if your report is in the same folder, go subreport propertis -> subreport(others)

 

in this tab

java.lang.String

 

$P{SUBREPORT_DIR} + "myreport.xxx"

 

change the last line for your subreport

 

".\myreport.xxx"

Yes, but that works only if I run main report from iReport. If I run the report from java app, I get the exception Could not load object from location : subreport.jasper.

 

I found a lot of people had the same problem, but no useful solutions (yet)...

I make this:

 

//Read Bd

List listaAnunciosP = this.fachada.obtenerAnunciosPorEstadoParaImpresion(anuncioBean, busqueda);

 

File reportFile = new File(getServlet().getServletContext().getRealPath("//WEB-INF//classes//reportes//busquedaAnunciosImpresionBoletin.jasper"));

 

parametros.put("rutaImagen", imagenLogo.getPath()); //This are constantes with the path

parametros.put("imagenLogoBoc", imagenLogoBoc.getPath());

parametros.put("imagenLogoCruz", imagenLogoCruz.getPath());

 

parametros.put("subreportPath", "//WEB-INF//classes//reportes//"); //Parameter with the for subreport

 

 

listaObjetosReportar = listaAnunciosP;

 

JasperReport jasperReport = (JasperReport)JRLoader.loadObject(reportFile.getPath());

JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, parametros, new JRBeanCollectionDataSource(listaObjetosReportar));

 

 

 

response.setContentType("application/pdf");

response.setHeader("Content-Disposition", "attachment; filename=vistaprevia.pdf");

response.setHeader("Expires", "0");

response.setHeader("Cache-Control", "must-revalidate, post-check=0, pre-check=0");

response.setHeader("Pragma", "public");

 

response.getOutputStream().write(jasperPrint);

 

In my report propertys

 

subreport propertis -> subreport(others) in this tab java.lang.String $P{subreportPath} + "subBusquedaAnunciosImpresionBoletin.jasper"

[dabor]

Looks like this is the "main" line:

parametros.put("subreportPath", "//WEB-INF//classes//reportes//");

 

My report/subreport path is something like this (since it's a desktop app):

com/company/project/reports (java way com.company.projects.reports).

 

They are inside jar file. Can I set the path into the jar file?

 

Thanks.

In my aplication, the reports are in src.main.resorces.reports, but this in package view of the program that i use for program. You must put the real path.

 

 

parametros.put("subreportPath", directoryHowIsInstallAplication+realPathReports);

 

 

 

[dabor]

Thank you for barring with me.

 

Can I get the path in my application? The program can be installed in different folders.

 

Another thing: the reports don't extract when I install the app, they remain in JARs... Can I specify path into JARs?

 

Any other idea or direction?

Thanks alot!
