Caching report sources

Caching a report source in the session variable allows it to be used multiple times efficiently. When a report source is not cached, the process of creating a new report source multiple times becomes fairly expensive. Furthermore, caching a report source allows reports with or without saved data to be refreshed.

The following example shows how to cache a report source in the session variable:

String report = "/reports/sample.rpt";
JPEReportSource reportSource;
reportSource = new JPEReportSource(report);
session.putValue("reportSource", reportSource);

Note:    If you are using a cached report source, the dispose methods for the viewer or report source should not be called until the report source is no longer being used.
