I am trying to configure Struts 2 with jasper. I have tried this using a little example but I got an error I was unable to recover this after spending two days on it. I have mentioned the error log and other code examples I have used.

Jars used 1. jasperreports-1.2.5.jar 2. itext-1.3.jar 3. jdt-compiler.jar
Can anybody help me to resolve this. I tried this out 2 days... with lot's of solutions given in the internet.
Hi I found the issue here. I included the struts2-jasperreports-plugin-2.1.8.1.jar and jdt-compiler-3.1.1.jar. I missed the struts2-jasperreports-plugin-2.1.8.1.jar. I also added -XX:PermSize=256m -XX:MaxPermSize=256m to server for raise perm space(But this is not related with the above issue).
Thanks Dave for your clue.
