I don't remember how I fixed it, because I've had a lot of problems with WS in Jboss and Jboss jbpm. The solution was in the libraries, the libraries that I used was wrong. Read this and take special attention at libraries [url]http://jbossws.jboss.org/mediawiki/index.php?title=Install_JBossWS [/url] Now, I tell us some changes I did with libraries. Hope this help us. Good luck!!! In case, Jboss-4.0.5 I think that I've replaced: --> commons-httpclient.jar for commons-httpclient-3.1.jar in jboss-4.0.5.GA\client folder. In case, Jboss jbpm3.2.2 I think that I've replaced: -->jboss-jaxws.jar_ for jboss-jaxws-ext.jar in C:\jbpm-jpdl-3.2.3\server\server\jbpm\lib -->jboss-jaxws.jar_ for jboss-jaxws-ext.jar in C:\jbpm-jpdl-3.2.3\server\server\jbpm\lib in C:\jbpm-jpdl-3.2.3\server\lib\endorsed In case, Jboss jbpm3.2.2 I think that I've deleted -->jboss-jaxws.jar of C:\jbpm-jpdl-3.2.3\server\client and C:\jbpm-jpdl-3.2.3\server\server\jbpm\deploy\jbossws.sar -->jbpm-jpdl.jar_ in C:\jbpm-jpdl-3.2.3\server\server\jbpm\lib I've created some post relacionates with WS. Maybe these could help us a little: http://www.jboss.org/index.html?module=bb&op=viewtopic&t=147494 http://www.jboss.org/index.html?module=bb&op=viewtopic&t=147344 http://www.jboss.org/index.html?module=bb&op=viewtopic&t=147234 View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4216893#...
