Hi, I have portal.ear built in java 5.0. I have deployed the ear on WAS/wps 6.1
Ear is deployed properly. But while running the app, class laoding issue appears.
The log is below......

I checked if class file is avaialble in the proper class loader hirarchy. Everything is fine. Is is class versioning/format issue or something else.

One issue is that grammerInfoIml class is using jdk1.4 build (the jar whhich consists it) .Is that the problem? Please Help
