jboss-seam.jar and jboss lib directory

[tom_goring]

Hi,

Hi can someone explain to me why (in a working web app) if I remove:

jboss-seam.jar
el-api.jar
el-ri.jar

from my EAR and module list in application.xml
and just place the jars in my jboss/lib dir I get the below stack trace when I invoke a page.

I.e. why to they need to go in the EAR file ?

Seam is not designed to be shared between different applications. If you tried to share Seam, I assume you'd see a shared application context with component conflicts between the two. I'd also imagine you'd see scanning and classloading problems too. The short story is that Seam should be treated as an application-specific library and not shared.
