新建project.如下图选择，
建立好以后的目录树如图:
- 添加新的webservice 接口和实现类。
依次选择File->New->Other
如图
点击Finish.
- 双击编辑HelloWorldImpl.java
代码如下:
public class HelloWorldImpl implements IHelloWorld 
{
public String example(String message) {
return "Hello World" + message;
}
}
- 修改WebRoot->WEB-INF->web.xml如下
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<servlet>
<servlet-name>helloworld</servlet-name>
<servlet-class>oracle.j2ee.ws.StatelessJavaRpcWebService</servlet-class>
<init-param>
<param-name>class-name</param-name>
<param-value>HelloWorldImpl</param-value>
</init-param>
<init-param>
<param-name>interface-name</param-name>
<param-value>IHelloWorld</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>helloworld</servlet-name>
<url-pattern>/HelloWorld</url-pattern>
</servlet-mapping>
</web-app>
- 添加新的build.xml
内容如下:

- 到你的hello的系统目录下面去，在与build.xml同级的目录下面运行ant
- 然后再myeclipse里面刷新工程会看到多了一个dist目录，这下面就有我们需要的war文件。
- 启动oc4j,在浏览器中输入http://localhost:8888/em/
然后登录。
- 依次选择Applications->deploy->
Browse选择你的dist下面的那个war文件，然后选择next.
Application Name随便添，Context-Root填写HelloWorld
然后下一步，deploy.
- 在浏览器中输入http://localhost:7788/HelloWorld/HelloWorld
看看效果。点击 example,parma0输入 Me. 点击 Invoke，怎么样，xml成功返回了。恭喜你，第一个servlet成功了。
