Crystal Reports SDK \ Report with XML Datasource doesn't refresh data in WebApp

Crystal Reports SDK \ Report with XML Datasource doesn't refresh data in WebApp

Good afternoon!

I'm trying to render a Crystal Report with a XML Datasource using the Java Runtime SDK for Crystal.

In the Crystal Reports XI App when I refresh the Parameters it reloads with new data, but when I do the same action in the WebApp  (Typing new data into parameters), the report loads the same data everytime.

This is my full code.

  //Open report.

  oReportClientDocument.open(reportName, 1);

  //Get the report source

  //Cache report source.

  //This will be used by the viewer to display the desired report.session.setAttribute("reportSource", reportSource);

  CrystalReportViewer crv = new CrystalReportViewer();

  crv.setName("Crystal_Report_Viewer");

  crv.setReportSource(reportSource);

  //Passing parameters

  crv.setHasRefreshButton(true);

  crv.setDisplayGroupTree(false);

  crv.refresh(); //Ask for parameters

  crv.processHttpRequest(request, response,

  getServletConfig().getServletContext(), out);

  crv.dispose();

  }

  //Redirect to the viewer page.

  //response.sendRedirect("CrystalReportViewer.jsp");

  } catch (ReportSDKException e) {

  out.print(e);

  }

Anyone could help me?

I've lost a lot of time trying to solve this.
