Joseph Hwang [http://community.jboss.org/people/aupres] created the discussion "Re: javax.xml.bind.UnmarshalException: unexpected element?" To view the discussion, visit: http://community.jboss.org/message/608450#608450 -------------------------------------------------------------- I found the reason. This message is the element does not need any namespace. For example, <ns1:arg0>aaa</ns1:arg0> brings this kind of exception. so to solve this exception is removing namespace. <args0>aaa</arg0> i hope this might be helpful  -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/608450#608450] Start a new discussion in JBoss Web Services at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
