Webservice - Java Client

[Md Uddin]

Hello Everyone,

I am very new with the web services. So, please bear with me if the question is stupid.

I am trying to get a better concept about writing a Java SOAP CLIENT (I understand the SOAP Service Implementation, I think .

Seems like there are different ways of writing a JAVA soap client. For example, in the below link
Java SOAP Client

(1) Java Web Service client Without Tool (without running 'wsimport'):
=> My understanding is, when we do this, it will not generate the service stubs on client side ...
# Please correct me if I am wrong, or what is the case here

Q: In this case, how can we access the HelloWorld class? (Client code can be anywhere other than SOAP Service Implementation package)

So how can we import

import com.mkyong.ws.HelloWorld;

or call

HelloWorld hello = service.getPort(HelloWorld.class);

Am I missing any step before writing this type of client?

In this example, "HelloWorld" interface forms the web service's "contract". These contracts (which have no implementation) are packaged with your client. That is, the interface is packaged into a jar file for example, and is add to your client app's classpath. On the contrary, if you generate the stub with wsimport, the tool will read the WSDL and generates the interface for you.

Hi Amir, thank you for your reply. So, for the below Web Service client (took it from 'Java Web service up and running' book, chapter 1), I need to do the same, right? Need to add the interface jar into the client class path and then run it ....?

package ch01.ts;
import javax.xml.namespace.QName; 
import javax.xml.ws.Service; 
import java.net.URL;
class TimeClient {
    public static void main(String args[ ]) throws Exception 
    { 
        URL url = new URL("http://localhost:9876/ts?wsdl");

        // Qualified name of the service:
        // 1st arg is the service URI
        // 2nd is the service name published in the WSDL
        QName qname = new QName("http://ts.ch01/", "TimeServerImplService");
   
        // Create, in effect, a factory for the service. 
        Service service = Service.create(url, qname);

        // Extract the endpoint interface, the service "port". 
        TimeServer eif = service.getPort(TimeServer.class);

        System.out.println(eif.getTimeAsString());
        System.out.println(eif.getTimeAsElapsed()); 
    }
}

Yes. The "TimeServer" is your interface, right?
