Could not instantiate Seam component: helloworldEntityManagerFactory

[mpssantos.mpssantos.gmail.com]

Hi there everyone.

Im a newbie on seam framework. I just follow the instruction on the Seam manual on chapter 3 - Getting started with Seam, using JBoss Tools.

Im using Eclipse 3.4 and JBoss Tools 3.0.0.CR1. I have create the project helloworld with no changes. But when i deploy it on the JBoss AS 4.2 it gives me this exception:

17:14:16,874 ERROR ((/helloworld)) Exception sending context initialized event to listener instance of class org.jboss.seam.servlet.SeamListener

I know it is very late to answer this question, but I will answer it anyway in case anyone has the same problem.

The problem is that you there are spaces in the path Documents and Settings and My Documents, use a path that doesn't have any spaces in it.
