I have a Web Service:

//javase imports
import java.io.InputStream;
import java.io.StringReader;
import org.xml.sax.InputSource;
//java eXtension imports
import javax.annotation.PostConstruct;
import javax.annotation.PreDestroy;
import javax.servlet.ServletContext;
import javax.xml.namespace.QName;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.soap.MessageFactory;
import javax.xml.soap.SOAPException;
import javax.xml.soap.SOAPFactory;
import javax.xml.soap.SOAPFault;
import javax.xml.soap.SOAPMessage;
import javax.xml.soap.SOAPPart;
import javax.xml.transform.dom.DOMSource;
import javax.xml.ws.Provider;
import javax.xml.ws.ServiceMode;
import javax.xml.ws.WebServiceProvider;
import javax.xml.ws.soap.SOAPFaultException;
import static javax.xml.ws.Service.Mode.MESSAGE;@WebServiceProvider(
    wsdlLocation = "WEB-INF/wsdl/eclipselink-dbws.wsdl",
    serviceName = "simpleService",
    portName = "simpleServicePort",
    targetNamespace = "urn:simpleService"
)
@ServiceMode(MESSAGE)
public class SimpleProvider implements Provider<SOAPMessage> {

    @PostConstruct
    public void init() {
        System.out.println("*****************init");
        ClassLoader parentClassLoader = Thread.currentThread().getContextClassLoader();
        InputStream eclipseLinkStream = parentClassLoader.getResourceAsStream(
            "/META-INF/eclipselink-dbws-or.xml");
        if (eclipseLinkStream != null) {
            System.out.println("/META-INF/eclipselink-dbws-or.xml = " +
                eclipseLinkStream.toString());
        }
        ServletContext sc = ProviderListener.SC;
        if (sc == null) {
            System.out.println("servlet context is null");
        }
        else {
            InputStream schemaStream = 
                sc.getResourceAsStream("/WEB-INF/wsdl/eclipselink-dbws-schema.xsd");
            System.out.println("WEB-INF/wsdl/eclipselink-dbws-schema.xsd = " +
                schemaStream.toString());
        }
    }
...

I also have a ServletContextListener:
import javax.servlet.ServletContext;
import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;

public class ProviderListener implements ServletContextListener {
    
    public static ServletContext SC = null;
    
    public  ProviderListener() {
        super();
    }

    public void contextInitialized(ServletContextEvent sce) {
        System.out.println("*****************ServletContext initialized");
        SC = sce.getServletContext();
    }

    public void contextDestroyed(ServletContextEvent sce) {
        // no-op    }
}


When I deploy to Glassfish, WebLogic and WebSphere, the order of execution is: Listener, then @PostConstruct

However, when I deploy to JBoss 5.10 (w Metro), the order is @PostConstruct then Listener.

Is this a known issue, or is there a workaround?

Thanks in advance,
Mike Norman
