ClassLoading Issue during migration from 4.2.1-GA to AS 6.0.1.Final
I'm trying to migrate my application from JBoss 4.2.1-GA to AS 6.0.1.Final. I initially had few jar conflicts and DTD compliance issues which were fixed. But right now, I'm blocked with this issue which i've no clue about. I deployed the same .ear file that was working properly in Jboss 4 and deployed it onto a jboss 6 instance ( 'app' is a clone of 'default' server profile). I get the below mentioned error when i try to start my server

It doesn't even print the class name that it is looking for. It is just trying to look for a class called ' ${project.main.class} '. Can someone please help here? Where should I start investigating this issue? Should this weird class name be coming from any of the contents inside the numerous war files i've inside my ear?
Below is the struture of my ear:
MyApp.ear
|
+- properties
| +- com
| +- App1
| +- A.properties
| +- B.properties
+- lib
| +- A.jar
| +- B.jar
| +- C.jar
|
+- META-INF
| +- application.xml
| +- jboss-app.xml
|
+- war
| +- D.war
| +- E.war
| +- F.war
|
+- ejb
| +- G.jar
| +- H.jar
| +- I.jar
Any pointers in this regards is highly appreciated. Thanks.
