deployment issues
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!
