Cannot obtain wsdl service (problem in JBoss 4.2 used to wor

[burakbayramli]

I have the following code that used to work in JBoss 4.0.4GA. After port to 4.2, server complained about "context roots being different, so I added @WebContext to all web services. Now server is fine, I can see the WSDL, but I cannot connect to the server using a Java client.

@WebService
@SOAPBinding(style=Style.RPC)
public interface Calculator extends Remote
{
 @WebMethod int add(int x, int y);

 @WebMethod int subtract(int x, int y);
}

@Stateless
@WebService(name="CalculatorService",serviceName="CalculatorService",endpointInterface="org.bilgidata.kitapdemo.service.Calculator")
@WebContext(contextRoot="/ggServices")
public class CalculatorBean implements Calculator
{
 public int add(int x, int y)
 {
 System.out.println("inside add");
 return x + y;
 }

 public int subtract(int x, int y)
 {
 System.out.println("inside subtract");
 return x - y;
 }
}

public class Client
{
 public static void main(String[] args) throws Exception
 {
 URL url = new URL("http://localhost:8080/ggServices/CalculatorBean?wsdl");
 QName qname = new QName("http://localhost:8080/ggServices/CalculatorBean",
 "CalculatorService");

 ServiceFactory factory = ServiceFactory.newInstance();
 Service service = factory.createService(url, qname);

 Calculator calculator = (Calculator) service.getPort(Calculator.class);

 System.out.println("1 + 1 = " + calculator.add(1, 1));
 System.out.println("1 - 1 = " + calculator.subtract(1, 1));
 }
}

The WSDL looks like

<definitions name='CalculatorService' targetNamespace='http://service.kitapdemo.bilgidata.org/' xmlns='http://schemas.xmlsoap.org/wsdl/' xmlns:soap='http://schemas.xmlsoap.org/wsdl/soap/' xmlns:tns='http://service.kitapdemo.bilgidata.org/' xmlns:xsd='http://www.w3.org/2001/XMLSchema'>

You're using the wrong namespace when creating the qname; it should be "http://service.kitapdemo.bilgidata.org/" according to your wsdl.

That worked.. thanks.

Type http://localhost:8080/tutorial/CalculatorBean?wsdl in IE browser address bar and store this in CalculatorBean.wsdl in a folder.
Go to the folder and use wsconsume CalculatorBean.wsdl.
Now go to the generated class file ClaculatorBeanService.class file and make this to java code by java decompiler. See the code
http://bean.webservice.tutorial.jboss.org/ in new QName.

That means in you Client.java you need to place
QName qname = new QName("http://bean.webservice.tutorial.jboss.org/","CalculatorBeanService");

Now run the program.
