finally I obtained the log (which full filled my file-system) It seems some recursive behavior is the cause of this hanging. here is the log: 2008-10-30 18:01:08,213 INFO [org.jboss.wsf.stack.jbws.WSDLFilePublisher] WSDL published to: file:/home/xtra/u/jdesa/mccg/jboss-4.2.2.GA/server/default/data/wsdl/wstest.war/EchoService23289.wsdl | 2008-10-30 18:01:08,394 DEBUG [org.jboss.wsf.framework.deployment.DeploymentAspectManagerImpl] EagerInitializeDeploymentAspect:Start | 2008-10-30 18:01:08,394 DEBUG [org.jboss.ws.metadata.umdm.UnifiedMetaData] Eagerly initialize the meta data model | 2008-10-30 18:01:08,397 DEBUG [org.jboss.ws.metadata.wsdl.xmlschema.JBossXSModel] Registered as anon type: {http://www.mccg.net/xsd/phoenix/base-types/claim.xsd:>claimInvolvedParty>listOfExtraAttr} -> Complex type name='http://www.mccg.net/xsd/phoenix/base-types/basic.xsd,#AnonType_...;, base type name='anyType', content type='ELEMENT', isAbstract='false', hasTypeId='false', final='0', block='0', particle='("http://www.mccg.net/xsd/phoenix/base-types/basic.xsd...;, derivedBy='RESTRICTION'. | There are 20Gb similar to the last line, I was not able to find out a pattern that let me understand what is happening it seems that the JBossXSModel (not sure what it is) is not capable of managing some kind of recursive references (?) inside an schema. I tried a basic example Contact->ListOfAddress and Address->ListOfContact and it worked ok.
