Hello All, I'm new to JBoss and have recently followed this link: http://www.jboss.org/community/wiki/JBWS181HelloWorld;jsessionid=CC455306... to successfully create a webservice. However, I face problem when I try to invoke the webservice using a Microsoft.Net client which I created. The following is the error which I got: org.jboss.ws.WSException: java.lang.UnsupportedOperationException: setProperty must be overridden by all subclasses of SOAPMessage Could someone help me out on this? Anyway, I am running JBoss Version 5.0.1 and I am using JDK6. Thanks for all your help. Regards, Abichap View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4223976#...
