I am new to Jasper Report, i need a few heads up before going forward with my development. My colleagues told me they are able to generate a basic report, but they are stuck with what approach should be used.

I was told we can either pass the datasource to jasper and write the queries within it, or we can query the database our-self and populate the result in bean and just pass that bean to jasper for rendering.

Kindly tell me which approach is more preferable ? and does passing the datasource have any performance hits compared to passing the bean. Also would like to know does first approach runs in a different jvm ?

Current Project Architecture Struts 2 - Spring 2.5 - Spring JDBC

Regards, Swapneel Killekar.

Feel free to ask any further queries.
