Hi! I am also facing the same error message but with string as follows: WARN [JavaWsdlMapping] Cannot find jaxrpc-mapping for type: {http://www.w3.org/2001/XMLSchema}string ... and this warning becomes fatal as it gives the following deployment time exception: org.jboss.ws.WSException: Cannot obtain java/xml type mapping for: {http://www.w3.org/2001/XMLSchema}string | at org.jboss.ws.deployment.JSR109MetaDataBuilder.buildParameterMetaDataDoc(JSR109MetaDataBuilder.java:513) Has anyone figured out how to solve it??? mnsharif View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3985244#...
