EAR is broken after redeployment

[carlsen]

My EAR application (containing three sar archives, a war archive and a jar archive) deploys and runs like a dream.

However after I redeploy the ear, the application is broken. I get no errors on redeployment, but when I try to access the web part of the application I get the following error:

Seems to me like I can no longer access the EJB beans for some reason.

Any help will be greatly appeciated...
