I have an application and I am generating Jasper Reports from it. But when I make request to generate the report, the time taken for the application to generate the report is quite long because the data set is very large(~100K rows) for the report.

So, by the time the report is generated successfully, the HTTP request gets timed out and the report is never downloaded.

How can I prevent this from happening?

The application is build with Spring 3.0, Hibernate and JasperReports.

    My guess is that your session is expiring at 20 minutes, try editing tomcat6/webapps/jasperserver/WEB-INF/web.xml

    <session-config>
    <!-- Default to 20 minute session timeouts -->
    <session-timeout>120</session-timeout>
</session-config>

    Also make use of ‘Run in background’ (right-click) which will save the output for you like a schedule.

    You can check tomcat6/webapps/jasperserver/WEB-INF/logs/jasperserver.log for any error messages.
