Default Getting Invalid Class Exception in tomcat

Hi Guys,
I am using the iReport1.2 for preparing the jasper files. I am using the
jasperreports-1.2.0.jar in my library files on the development side. When i run my application in my tomcat(5.5.9) i get the InvalidClassException.

java.io.InvalidClassException: net.sf.jasperreports.engine.base.JRBaseReport; local class incompatible: stream classdesc serialVersionUID = 10200, local class serialVersionUID = 603

From some other stuff i saw on the internet, i know that this is some version related problem.So i checked the versions in the iReport lib and the lib foleder in my developement directory.They are the same. But somehow i am stuck . The same error keeps repeating.


Please help..

Thanks in advance.

try checking your whole development environment for another copy of jasperreports lib. if the vm says the versions don't match then ... there must be some other version.

btw how did you check the versions match? you compared the classfiles?
