Thanks for your answer Opalka. What you told me didn't works. Then i tested to move swaref.xsd file to jboss-4.2.3.GA\server\default\deploy\jboss-web.deployer\ROOT.war location and to rewrite the generated wsdl: change http://ws-i.org/profiles/basic/1.1/swaref.xsd to http://localhost:8080/swaref.xsd . and it works!!!. I don't know if this is the write solution , (i 've to update the wsdl file everytime i redeploy my app)...
thanks
