Getting NullPointerException during the binding process in WAS 7.0 on WinXP
Gota
I'm getting NullPointerException when I try to start my application on WebSphere Application Server 7.0.0.0, running on Windows XP SP3, installed with WAS 7.0 Win 32bit.zip.
The application is based on Seam 2.2.0.GA, which provides some example applications deployable to WAS 7.0 and this example application (jboss-seam-booking-jee5) is running fine on thie WAS7.0.
I've installed on my local windows box and then created a simple application with Maven2 by following the working example application and deployed to WAS, main components/configurations as follows, (also ear file is attached):
application.xml
seam-module-packaging
seam-module-web-1.0.2-SNAPSHOT.war
/seam-ejb-ex
seam-module-ejbs-1.0.1-SNAPSHOT.jar
jboss-seam-2.2.0.GA.jar
ejb-jar.xml
RegisterAction
seam-ejb-ex/AuthenticatorAction
Session
au.com.spatialvision.ice.prototype.Authenticator
org.jboss.seam.ejb.SeamInterceptor
*
org.jboss.seam.ejb.SeamInterceptor
persistence.xml
org.hibernate.ejb.HibernatePersistence
!--
jdbc/__default
java:/DefaultDS
DefaultDatasource
!--
Class loader
Class loader order: Classes loaded with local class loader first (parent last)
When I try to start the application, it fails and the log shows as follows:

Could you please help me identifying what could cause the exception in: at com.ibm.ws.metadata.ComponentDataObject.getAnnotationsFromClass(ComponentDataObject.java:994)
I am new to WAS and it has been a big challenge to get this point with help from many good references, forum posts etc. however this particular exception has not been mentioned anywhere yet.
Thank you for your help.
