1464735 - How do I clean up the viewer when viewing a report using CR for Java

When viewing a report using CR for Java, the report object is not cleaned up right away.

To clean up the report, use the following code in your cleanup page:

<%@ page import="com.crystaldecisions.report.web.viewer.CrystalReportViewer"
%><%
CrystalReportViewer crystalReportViewer;
Object reportSource;

reportSource = session.getAttribute("ReportSource");

crystalReportViewer = new CrystalReportViewer();

crystalReportViewer.setReportSource(reportSource);
crystalReportViewer.dispose();

%>

Some ways to have a clean-up page called are:

• Have this page called when a new report is requested, to clean up any previously viewed reports
• Create a 'Logoff' button, that the user clicks that posts to this page
• Wrap the viewer in a Frame, or create a hidden Frame, that on page unload events invokes JavaScript that calls this page
• Put the code in a HTTP Session Listener instance registered with the web application to listen for HTTP Session timeout events.
