classcastException when trying to deploy

[Kamalanathan Raman <Ka...@infosys.com>]

Hi , iam new to Geronimo, can u help me out in figuring out why this
problem is occurring, when I try to deploy the application. What I have
done is, I have added 2 ejb jars as dependencies in Geronimo-web.xml .I
added these two ejb jars in the repository folder of geronimo 1.1. and
the EAR that iam trying to deploy also contains these two EJB jars may
be because of that it is showing this error or wat else. Any pointer in
this regard will be duly appreciated.

Kamalanathan,
Can you check your deployment descriptors? In particular your bean  
names? Do you have an entity bean and a session bean with the same name?

My initial thought was you had a classloader issue. However, it looks  
more basic than that...
