I have updated the JasperReportsIntegration kit. The new libraries 4.6.0 of JasperReports are now included.
The integration kit itself has not changed. Thus you can simply update the JasperReports libraries to version 4.6.0. This process is explained in the FAQ.
You can find all details, FAQ and downloads here: http://www.opal-consulting.de/tools .
Hopefully I will publish another new version soon, I would like to include an Oracle connection pool in order to simplify the configuration of the data sources which is completely different on all J2EE servers :(. I did this for performance reasons but it didn't turn out to be such a good choice.
