NoClassDefFoundError upon migration to 2.6

Megha Nidhi Dahal

Hello,

We have recently migrated to BIRT 2.6, It is working fine but recently in one of the local installations(this was the first time application was migrated from 2.5.1 to 2.6 in this machine), we saw an error that says:

for first time and then,

I verified that the jars are proper and everything else is as expected, design files are at place. Upon googling I found there is a bug related to this and some steps to rectify. It says to exclude some jars from classpath, but I'm confused as why is the issue only in some cases i.e. only in this machine, while it is working fine elsewhere, if it was issue with the classpath, it shouldn't have worked anywhere.

I might have missed out something. Need help.

Got it fixed, problem with the classpath.
