Are you using web services as they came with JBoss AS 4.2, or did you install a different version? How did you create the client stubs? Did you create them using 4.2 (or if you installed a different version of JBossWS, did you use that)? Does JBOSS_HOME on the client point to the 4.2 JBoss AS? P.S. Hope I caught you before the bus came... View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4066694#...
