Looked into JDK 1.5/JDK-1.4 API this method is not available. However this error is not thrown by 4.0.4 version.
Process gets deployed from eclipse console fine.
Following jars required during deployment of the ear.

Hibernate 3.0 jar
Jboss-hibernate.jar
Jboss-backport-concurrent.jar
Commons-io_xxx.jar
Commons-fileupload.jar
Commons-collections.jar

Does anybody have an idea or tried this.
Tell me if I am going wrong anywhere.

Thanks in advance
Regards
