Hola buenas tardes.

Estoy realizando una aplicación en la cual se requieren reportes. Ya diseñé con el Report Desinger de Pentaho el informe que necesito y me lo guarda en \"nombre del informe\".report y puedo generar tambien el xml. Tengo un servlet que toma el xml pero no me arroja nada. Podrias ayudarme con los ejemplos que tienes en jps y te mando tambien el servlet con el que estoy trabajando.

package dsrx;

import java.io.IOException;
import java.net.URL;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.ServletException;
import javax.servlet.ServletOutputStream;

import org.jfree.report.JFreeReportBoot;
import org.jfree.report.JFreeReport;
import org.jfree.report.modules.parser.base.ReportGenerator;
import org.jfree.report.modules.output.pageable.pdf.PdfReportUtil;
import org.jfree.report.resourceloader.ResourceFactoryModule;
import org.jfree.resourceloader.*;

/**
* Processes a report.
*
* @author Thomas Morgner
*/
public class informedsrx1 extends HttpServlet
{
public informedsrx1()
{
}

public void init() throws ServletException
{
JFreeReportBoot.getInstance().start();
}

protected void doGet(final HttpServletRequest request,
final HttpServletResponse response) throws ServletException, IOException
{
final String reportDefinition = request.getParameter(\"report-definition\");
final URL reportUrl = getServletContext().getResource(reportDefinition);
if (reportUrl == null)
{
response.sendError(HttpServletResponse.SC_BAD_REQUEST);
return;
}

try
{
final JFreeReport report = ReportGenerator.getInstance().parseReport(reportUrl);
response.setContentType(\"application/pdf\");

final ServletOutputStream stream = response.getOutputStream();
if (PdfReportUtil.createPDF(report, stream) == false)
{
log(\"Failed to process the report\");
response.sendError(HttpServletResponse.SC_INTERNAL_SERVER_ERROR);
return;
}
stream.flush();
}
catch (ResourceException e)
{
log(\"Failed to parse report\", e);
response.sendError(HttpServletResponse.SC_INTERNAL_SERVER_ERROR);
}
}

protected void doPost(final HttpServletRequest httpServletRequest,
final HttpServletResponse httpServletResponse) throws ServletException, IOException
{
doGet(httpServletRequest, httpServletResponse);
}
}

a traves de un jsp, le paso el nombre del archivo como parametro. pero no despliega nada. Estoy trabajando con neatbeans y esto sale:
