[jboss-user] [JBoss Seam] - deployment issues

[hun1997]

Hi - I'm looking at using Seam as a solution for a large-scale web application, however I am growing increasingly frustrated by two errors that keep coming up:

1. "NoClassDefFoundError" for beans I have created and definitely exist in the EAR
2.  "value of context variable is not an instance of the component bound to the context variable: ..."

Usually, redeploying once (sometimes more) will fix these problems when they crop up. 

What are causing these?  It doesn't seem like it's my code, since a redeployment fixes them.  What can I do so that these stop becoming an issue?

(I'm using JBoss 4.2.1 and Seam 1.2.1)

Here's an example stacktrace of simply calling my authenticator bean from a login form.  Thanks in advance!
