The JavaBean datasource does NOT work.

 

However, you can write a JRCustomDataSource to access your beans for the data for your report.

 

For designing the report (opposed to the connection for the actual data) you CAN use "Report Query - JavaBean Datasource" tool to register the fields for your Bean. Just make sure the Bean is in the classpath for iReport (and if you are utilizing EJB's, that your J2EE.jar is also in the classpath).

 

Hope this helps!
