I tried to deploy two J2EE applications (each packed as a ear file) on one JBoss instance. Each of these webapps contains WS definition. The problem I encountered is when I try to invoke one of the deployed WSs no java type mapping or SEI mapping is found, and the appropriate error messages appear in logs. But when I try to invoke the same WS after redeploying the other application without any WS metadata (I simply deleted webservices.xml and jaxrpc-mapping.xml from the other app's ear file), everything maps fine and the webservice is working. The two webservices have nothing in common - especially they do not share any namespaces or java objects. Does anybody know the reason why is this happening?
