Avoid hogging & stuck threads in WLS when calling Web Services

If your app server has lots of threads waiting for response from a ws endpoint that doesn’t run as well as you would like you should start thinking in some kind of timeout control implementation.

If your are using OSB this configuration can be done in the PS settings, but if your integration in point to point tell your developers/partners to implement timeout this way:

Class1Service class1Service = new Class1Service();

        x = class1Service.getClass1Port();

        setWSTimeout(x, 30000); // esperamos 30 segundos

       x.getCosa(); // si mi servicio no responde en 30 segundos habrá una excepción que poder atrapar


    public void setWSTimeout(Object o, int timeout){

        Map<String, Object> context = ((BindingProvider)o).getRequestContext();

        //Set timeout params

        context.put(“com.sun.xml.internal.ws.connect.timeout”, CONST_CONNECT_TIMEOUT);

        context.put(“com.sun.xml.internal.ws.request.timeout”, timeout);

        context.put(“com.sun.xml.ws.request.timeout”, timeout);

        context.put(“com.sun.xml.ws.connect.timeout”, CONST_CONNECT_TIMEOUT);


When timeout is reached you can catch the exception avoiding stucks:
