I followed the example provided at <a class='bbc_url' href='
http://wiki.eclipse.org/RCP_Example_(BIRT)_2.1'>RCP Example (BIRT) 2.1 - Eclipsepedia</a> and used WebViewer plugin to pass parameters from application and display the report using frameset servlet. <br />
<br />
// Start the WebViewer server<br />
WebViewer.startup(currentWebApp.getName());<br />
String preParameters = createURL("frameset", reportName, format);<br />
String reportParams = getReportParameters();<br />
// Display the report in SWT browser<br />
String finalUrl = preParameters + reportParams;<br />
browser.setUrl(finalUrl);<br />
<br />
The report gets displayed without any issues and I am able to export the output to Excel/PDF. But when I try to invoke the print functionality, I am getting the following error. Why is the session expiring? Is there anyway that I could set the session parameters.<br />
<br />
- The viewing session is not available or has expired.<br />
