@WebServiceProvider @Stateless and @PostConstruct

[jahhaj]

I have a web service which is stateless but needs to do some one time initialization.

Originally I used the @WebService, @Stateless and @PostConstruct annotation and everything worked well. My @PostConstruct method was called once only (and my ctor incidentally) no matter how many times the web service was called.

For reasons beyond my control I've had to switch to @WebServiceProvider and have my service class implement Provider SOAPMessage. Now @Stateless and @PostConstruct don't seem to work. My ctor is called once for each service call and my post construct method is never called at all.

Have I done something wrong? Or misunderstood something (very likely).

If it's not possible to get this working using annotations what would be the best way to get my one-time initialization to work.

Thanks,
John

The @Service can help you http://docs.jboss.org/ejb3/app-server/reference/build/reference/en/html/jboss_extensions.html

Thanks but it didn't work, maybe because @Service only applies to EJB's? Anyway my code (an except)

@org.jboss.annotation.ejb.Service
@WebServiceProvider(
 targetNamespace = DDAA.NAMESPACE,
 wsdlLocation = "WEB-INF/wsdl/ddaa.wsdl")
@ServiceMode(value = Service.Mode.MESSAGE)
public class DDAA implements Provider<SOAPMessage>
{
 private static final Logger log = Logger.getLogger(DDAA.class.getName());

 public DDAA()
 {
 log.info("DDAA ctor");
 }
}

The ctor is called each time the DDAA web service is called.
