I'm getting the following error when starting up an application migrated from Websphere 4 to 6. Any clue on what it could be? The application installs cleanly, but during startup it throws this error.

I too am getting a similar error. I am going from WebSphere 5.1 to 6.1 - it seems to not like the Struts Taglib jar. I haven't found any solution yet - should I find something, I'll post again.

(For best results: hand wash in cold, tumble dry low. For not so good results: drag through puddles, pound on rocks, air dry on tree branch.)
