JAX-Ws Based Spring Webservices W/o Arguments

Here we are going to create a JAX-Ws based webservices in spring that simply return a message without taking any arguments.

GreetingServiceInter.java
-------------------------
package com.satya;

public interface GreetingServiceInter {
    public String sayHello();
}


GreetingService.java
------------------------
package com.satya;
    
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import javax.jws.soap.SOAPBinding.ParameterStyle;
import org.springframework.stereotype.Service;

@SOAPBinding(parameterStyle=ParameterStyle.BARE)
@WebService(serviceName="GreetingService")
@Service("greetingService")
public class GreetingService implements GreetingServiceInter
{
 public String sayHello()
 {
  return "Hello from Greeting Service";
 }
}
ServiceExposer.java
-----------------------
package com.satya;
import org.springframework.context.support.*;
public class ServiceExposer {
    public static void main(String[] args)
    {
        FileSystemXmlApplicationContext ctx=new FileSystemXmlApplicationContext("MyCfg.xml");
        System.out.println("Service Exposed Successfully ");
    }
}

MyCfg.xml

<bean class="org.springframework.remoting.jaxws.SimpleJaxWsServiceExporter">
                   <property name="baseAddress" value="http://localhost:1234/" />
</bean>
 </beans>



Note:-Run ClientExposer.java to expose your GreetingService.java (sayHello()) as WebService
This set up will use Java WebServer(jdk1.6+ supported),to expose the webservice.
Here we have decided to expose the webservice at port no 1234,

To view WSDL
                             http://localhost:1234/GreetingService?WSDL
