I'm trying to run the GWSOAP javaClient demo application in NetBeans. It
works great in Java 5, but when I try running it using JAVA 6, I get the
following error:

java.lang.ClassCastException:
com.sun.xml.internal.messaging.saaj.soap.ver1_1.Me ssage1_1Impl cannot be
cast to com.sun.xml.messaging.saaj.soap.MessageImpl

com.novell.groupwise.ws.GroupWisePortType_Stub.log inRequest(GroupWisePortType_Stub.java:3024)
at javaclient.Login.loginActionPerformed(Login.java:4 11)


Are there any known errors or workarounds for this scenario?
Best regards
