I deployed jbossws-metro-3.0.5.GA at JBoss 4.3.0.GA_CP01 (ant deploy-jboss422). I begun to receive "javax.xml.ws.WebServiceException: Unable to load Provider: Failed to load javax.xml.ws.spi.Provider: org.jboss.ws.core.jaxws.spi.ProviderImpl" at my ws client. So, I traced the problem to production/lib/jboss-jaxws.jar and roduction/lib/jjboss-saaj.jar After I removed the libraries, everything went back to normal. Do you need a bug filled at Jira ?
