在运行时覆盖或设置Web服务端点以获取使用wsimport生成的代码

Question

Using code that was generated with wsimport , can the service endpoint be overridden without having to regenerate the code?

I have written a simple java webservice, following are the steps:

1. I compile the java class and generate a war file
2. Deploy the war file to my app server (tomcat)
3. Access the WSDL via the URL eg localhost:8080/service/helloservice?wsdl
4. use the URL with wsimport.bat to generate client classes for example: wsimport http://localhost:8080/service/helloservice?Wsdl
5. I use those classes in my client app to call the service

The problem is that is the service is deployed on an app server running on port other than 8080, the communication between client and service never happens. I am trying to know what is the best way to create stubs that does not have server and port hardcoded in the stub used by the client.

Answer 1

Your client can set the end-point in the service "port" at runtime via the BindingProvider interface.

Consider the JAX-WS client in this JAX-WS tutorial . Another way to write this code would be:

HelloService service = new HelloService();
Hello port = service.getHelloPort();
BindingProvider bindingProvider = (BindingProvider) port;
bindingProvider.getRequestContext().put(
      BindingProvider.ENDPOINT_ADDRESS_PROPERTY,
      "http://foo:8086/HelloWhatever");
String response = port.sayHello(name);

Caveat: I haven't downloaded the tutorial code and tested this code against it.

I faced the same issue, and it was terrible coz once the code is moved to production it always looked for the hardcoded WSDL location ie Windows C:........etc

I have gone thru various post and pages to find the answer however all was failing then found myself a way by looking at the Service Class generated by JAX-WS imports.

I had to override the JAX-WS WSDL location implementation in my calling class like this.

URL baseUrl;
URL wsdlURL = null;
baseUrl = <your Services>.class.getResource(".");
try {
    wsdlURL = new URL(baseUrl, "http://<your path>?wsdl");
    } catch (MalformedURLException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
}

<your Services> yourServices = new <your Services(wsdlURL,new QName("your namespace", "<your service name>"));
System.out.println(Services.getWSDLDocumentLocation());
YourInterface YourInterfacePort =  yourServices.getServicePort();
BindingProvider bindingProvider = (BindingProvider)YourInterfacePort;
bindingProvider.getRequestContext().put(
          BindingProvider.ENDPOINT_ADDRESS_PROPERTY,      url);

YourInterfacePort.methods();
