[FIXED] Web service client getting NullPointerException from getMyWSPort

Issue

I have created a simple web service called TimeServerBean. It's working properly, the GlassFish server is running and I can access the WSDL file from browser. Note this is done on local host.

Next I created a new project and made a web service client and provided the URL to the WSDL file. Then I got some classes generated (JAX-WS). On my client class I have this code:

public class SimpleClient {

    @WebServiceRef(wsdlLocation = "wsdl url here")
    static TimeServerBean_Service service;
    private TimeServerBean bean;

    public SimpleClient() {
         bean = service.getTimeServerBeanPort();
    }
    //methods here
}

Although I get null when I call the getTimeServerBeanPort. During that time the server is up and running. Is there some obvious mistake? TimeServerBean and TimeServerBean_Service are generated classes from the WSDL.

Solution

Two suggestions:

1. DEFINITELY put your method in a try/catch block

2. Assuming that service itself is null, then try doing an explicit service.create() instead of using the @WebServiceRef annotation. Here's a good example (Websphere, but same principle):
