I have a JAX-WS 2.0 RI based project deployed on JBoss 4.0.4.GA that I am upgrading to JBoss 4.2.1.GA with JBossWS 2.0.1.GA.

An endpoint packaged in a war makes use of @PostConstruct, as well as some Handlers that make use of @PostConstruct as well. @PostContruct on the web service class is never invoked, however @PostConstruct on on of the Handlers does get invoked. I'll try experimenting with removing the handlers, and see if it's something like JBossWS will only invoker one @PostConstruct method per web service.

The following port interface was generated from the WSDL:

@WebService(name="ImportPort", targetNamespace="urn:HVODWebService")
@HandlerChain(file="ImportPort_handler.xml")
@SOAPBinding(parameterStyle=SOAPBinding.ParameterStyle.BARE)
public interface ImportPort {

 @WebMethod
 @WebResult(name="ImportResponse",
 targetNamespace="urn:HVODWebServiceTypes",
 partName="response")
 public ImportResponse submitJob(@WebParam(name="ImportRequest",
 targetNamespace="urn:HVODWebServiceTypes",
 partName="request")
 ImportRequest request)
 throws ServiceFault;

}

The following implementation makes use of @PostConstruct, but never gets invoked:

@WebService(endpointInterface="com.xo.nextgen.hvodwebservice.wsdl.ImportPort")
public class ImportWebService implements ImportPort {

 @Resource
 private WebServiceContext context;

 @PostConstruct
 public void initialize() {
 ...
 }

 @PreDestroy
 public void destroy() {
 ...
 }

 public ImportResponse submitJob(ImportRequest request)
 throws ServiceFault {
 ...
 }

}

The following handler.xml is used to inject two Handlers:

<?xml version="1.0" encoding="UTF-8"?>
<javaee:handler-chains xmlns:javaee="http://java.sun.com/xml/ns/javaee">
 <javaee:handler-chain>
 <javaee:handler>
 <javaee:handler-name>SchemaValidation</javaee:handler-name>
 <javaee:handler-class>com.xo.nextgen.hvodwebservice.wsdl.handler.SchemaValidationHandler</javaee:handler-class>
 </javaee:handler>
 <javaee:handler>
 <javaee:handler-name>FaultNotification</javaee:handler-name>
 <javaee:handler-class>com.xo.nextgen.hvodwebservice.wsdl.handler.FaultNotificationHandler</javaee:handler-class>
 </javaee:handler>
 </javaee:handler-chain>
</javaee:handler-chains>

The following Handler interestingly does have it @PostConstruct method invoked:

public class SchemaValidationHandler
 implements LogicalHandler<LogicalMessageContext> {

 @PostConstruct
 public void initialize() throws WebServiceException {
 ...
 }

 @PreDestroy
 public void destroy() {
 }


 public boolean handleMessage(LogicalMessageContext context) {
 ...
 }

 public boolean handleFault(LogicalMessageContext context) {
 ...
 }

 public void close(MessageContext context) {
 ...
 }

}

Also the exact same behavior occurs with JBoss 4.2.1.GA with it's native JBossWS 1.2.
