I upgraded from Jasper 1.0 to Jasper 1.2.5.

 

Are there any step by step instructions on how to install it in a Windows XP environment?

I keep getting this error.

NoClassDefFoundError: org/apache/commons/java

 

Of course I also upgraded to iReports 1.2.5 and recompiled my .jrxml

There seem to be a problem with the CloasLoader

 

Any help would be greatly appreciated

Hi,

 

Put the commons-javaflow.jar into the classpath of you application. You can find it in the /lib directory of our project distribution.

 

I hope this helps.

Teodor

Thanks Teodor. It sure helped.

I wanted to prevent the memory leak problem in JasperViewer. I think this version solves most of the problem.

For whoever is interested, I also added a line of code after a call to viewReport that I think helps preventing memory leaks:

viewer.dispose();

viewer = null;

Where viewer is an instance of JasperViewer
