WAS 6.1 app runs in WAS 7 but it is flaky

Hi,

I have an ear file that runs in WAS 6.1. We have deployed it to WAS 7. The app comes up but when I click on links in the page (jsp), I get a 500 error sometimes.

Error 500: java.lang.NoClassDefFoundError: com.xxx.mx.db.MxCoDB (initialization failure)

What could be the issue here? Different versions of jar files?

Thanks

The error message says there was an "initialization failure" when trying to load that class. I don't think speculating about possible causes of that error is the best approach; if it were my problem I would be looking in the Websphere logs to see exactly what that failure was.
 
I agree. Here's the link: http://aspose.com/file-tools
