No, i have not checked with the JDK1.5 with Jboss. Giving more details about the problem occurrence : There are two webservices client present bundled in different applications but deployed on the same jboss instance. When any of them initializes first, then that client works smoothly without this error. But, the second client always give this error. Hope this might give some helpful info about the error. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/552976#552976] Start a new discussion in JBoss Web Services Metro at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
