How to determine Jasper version

[willemdankier]

How do I determine the version of the Japser Reports Library being used?

Let me explain why I want this. We use iReport to build jrxml files. We save these files in the database along with a compiled version of the report. We compile the report with the Japser Java Library.

Over time we use newer Japser Library versions, but there may be compiled reports in the database, that were compiled with older versions of Jasper. I would like to compare the version current runtime Jasper Libarary with the version that is used to compile a existing report. And when that differs, I want the software to recompile te report. If I can not determine the version of a compiled report, than I would like to save the Japser version at the moment of compilation, so I can compare that.

So, is there any way to determine the currently used Japser Library version and, if possible, the version of a compiled report?

Thanks in advance for your valuable time!
