Re: JasperReports Serialization error with JRDataSource

2011-02-25 Thread Gabriel Landon 

That's how I use it not to have Serialisation problem :

JRResource resourcePDF = new
JRConcreteResource(reportFile, new PdfResourceHandler())
{
public JRDataSource getReportDataSource() {
//retrieve you data
//...
return new JRBeanCollectionDataSource(yourCollection);
}

   public Map getReportParameters() {
Map params = new HashMap();
//set your parameters
params.put("base_path",
WebApplication.get().getServletContext().getRealPath(""));
return params;
   }
};


Hope this help.
Gabriel.

By the way, this is the exception I'm getting:

JasperReports Serialization error with JRDataSource

2011-02-25 Thread Bruno Borges 
Hey all,

I'm trying to build a ResourceLink to a JRResource but there's a
Serialization exception going on.  Here is the snippet code:

final ServletContext context = ((WebApplication)
getApplication()).getServletContext();
final File reportFile = new
File(context.getRealPath("/reports/employeeReport.jasper"));

final Map parameters = new HashMap();
parameters.put("BaseDir", new File(context.getRealPath("/reports")));
JRResource pdfResource = new JRConcreteResource(reportFile, new
PdfResourceHandler()).setReportParameters(
parameters).setReportDataSource(new
JRBeanCollectionDataSource(service.listAll()));

add(new ResourceLink("linkToPdf", pdfResource));

The service variable is a @SpringBean.

Any idea anyone? (Eelco, specially... who wrote jasper integration on
wicketstuff)...

:-)
