Getting rid from error "setProperty must be overridden by all subclasses of SOAPMessage" in JBoss 4.2.3

I am using JBoss 4.2.3 with JDK 1.6.0_11 and had the following error while running client to call webservice as following:

ERROR [SOAPFaultHelperJAXWS] SOAP request exception
java.lang.UnsupportedOperationException: setProperty must be overridden by all subclasses of SOAPMessage
at javax.xml.soap.SOAPMessage.setProperty(Unknown Source)
at org.jboss.ws.core.soap.SOAPMessageImpl.(SOAPMessageImpl.java:83)
at org.jboss.ws.core.soap.MessageFactoryImpl.createMessage(MessageFactoryImpl.java:217)



Solution: https://jira.jboss.org/jira/browse/JBWS-1439

Simple eclipse problem screwed me up..

I imported an ear file and since this file did not have java source file so i copied all source file in src folder generated by eclipse.

what is next...I needed to modify in source code and deploye on JBoss server.
So, i tried to deploy it on JBoss server but message was showing..."Publish failed using Ant publisher".

I tried to fix this issue by changing so many configuration but i couldn't :(
even i tried to googling this problem but i did not find any luck.
so i tried to copy the message from details and when i copied and paste in text editor there was more messge as following.

Publish failed using Ant publisher
unable to assemble module
duplicate entry: org/jboss/seam/example/registration/test/RegisterTest.class

ohhh...this was silly problem... later I realised that there was and imported classes that should be deleted so I deleted all modified class from ImportedClasses and this got fixed :-)
