DropListener NoClassDefFoundError
My setup
Richfaces 3.1.0
Seam 1.2.1
JBoss 4.0.5
I am trying the richfaces drag and drop example with code included below.
I was able to compile the source code and deploy it.
The application renders fine and I can drag the framework from source list to destination area.
But the moment I drop it , I get the following error .
java.lang.NoClassDefFoundError: org/richfaces/event/DropListener
I checked for this class in the richfaces jars and found it in the richfaces-api jar.
I have already packaged the richfaces libraries (the 3 richfaces jars i.e ui, impl and api) in the WEB-INF/lib .
