Hello, We have both Jboss 1.2 and Xfire client jars on our classpath. At runtime, when javax.xml.ws.Service tries to create a ServiceDelegate, it calls Provider.provider().createServiceDelegate(wsdlDocumentLocation, serviceName, this.getClass()); Which always and only returns an XfireProviderImpl. I know that according to JAXWS specs, i can set the JAXWSPROVIDER_PROPERTY. But my question is, can I programatically return different ProviderImpls in order that to run both clients? or must I choose only 1. Thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4103896#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
