[Java] JAX-WS Using Spring Framework

Step-by-step:

1. In Eclipse, new a dynamic web project, say EchoService. 
2. Provide an interface for EchoService, say EchoService.java, in a custom demo package.
   

   package demo;
   
   public interface EchoService {
       
       public String echo(String word);
       
   }

3. Provide an implementation for EchoService interface, say EchoServiceImpl.java.
   

   package demo;
   
   public class EchoServiceImpl implements EchoService {
   
       public String echo(String word) {
           return word;
       }
   
   }

4. Provide an endpoint to exporting EchoService web service. Make sure that all Spring framework JAR files and commons-logging JAR file are in the build path.
   

   package demo;
   
   import javax.jws.WebMethod;
   import javax.jws.WebParam;
   import javax.jws.WebService;
   
   import org.springframework.beans.factory.annotation.Autowired;
   
   @WebService
   (
       targetNamespace = "http://demo/", 
       serviceName="EchoService"
   )
   public class EchoServiceEndpoint {
   
       @Autowired 
       private EchoService biz;
       
       @WebMethod
       public String echo(
               @WebParam(name = "word") String word
       ) {
           return biz.echo(word);
       }
       
   }

5. Provide applicationContext.xml.
   

   <?xml version="1.0" encoding="UTF-8"?>
   
   <beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:util="http://www.springframework.org/schema/util"
       xmlns:tx="http://www.springframework.org/schema/tx" 
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="
           http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
           http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context-2.5.xsd">
   
       <context:annotation-config />
       <bean id="echoService" class="demo.EchoServiceImpl" />
   
       <bean class="org.springframework.remoting.jaxws.SimpleJaxWsServiceExporter">
           <property name="baseAddress" value="http://localhost:8888/" />
       </bean>
   
       <bean id="echoServiceEndpoint"
           class="demo.EchoServiceEndpoint">
       </bean>
   </beans>
   

6. Provide a standalone web service publisher, say Main.java.
   

   package demo;
   
   import org.springframework.context.ApplicationContext;
   import org.springframework.context.support.ClassPathXmlApplicationContext;
   
   public class Main {
   
       private static final ApplicationContext ctx = new ClassPathXmlApplicationContext(
               "demo/applicationContext.xml");
   
       public static void main(String[] args) {
           System.out.println("Start Standalone JAX-WS Server...");
       }
   
   }

7. Run as Java application (demo.Main). Please check http://localhost:8888/EchoService?wsdl.
   

Enjoy!
