用cxf封装了一个应用程序，用了struts2，想部署到tomcat中，出了问题10

首先我把server端和client端都写成应用程序（就是有main函数的那种），server端代码
AnsysServer.java

package cn.edu.sjtu;
import javax.xml.ws.Endpoint;
public class AnsysServer {

protected AnsysServer() throws Exception {
System.out.println("Starting Server");
Object implementor = new cn.edu.sjtu.AnsysImpl();
String address = "http://localhost:9090/AnsysPort";
Endpoint.publish(address, implementor);
}

public static void main(String args[]) throws Exception {
new AnsysServer();
System.out.println("Server ready...");

Thread.sleep(5 * 60 * 1000);
System.out.println("Server exiting");
System.exit(0);
}
}

client端代码：
AnsysClient.java

package cn.edu.sjtu;
import javax.xml.namespace.QName;
import javax.xml.ws.Service;
import javax.xml.ws.soap.SOAPBinding;
public class AnsysClient {

public static void main(String[] args) throws Exception {
QName serviceName = new QName("http://sjtu.edu.cn/", "AnsysService");
QName portName = new QName("http://sjtu.edu.cn/", "AnsysPort");

Service service = Service.create(serviceName);
service.addPort(portName, SOAPBinding.SOAP11HTTP_BINDING,"http://localhost:9090/AnsysPort");
cn.edu.sjtu.Ansys client = service.getPort(portName,cn.edu.sjtu.Ansys.class);
//Ansys client = new AnsysImpl();
// Insert code to invoke methods on the client here
client.init();
client.run();
}
}

还有个实现类AnsysImpl.java
代码不贴了，很长。

先运行AnsysServer.java，再运行AnsysClient.java，可以正常运行封装的应用程序Ansys90.exe。

我想做成这样，AnsysServer.java不变（仍然有main函数），然后打开浏览器，访问一个页面，点击页面中一个
按钮来启动client，AnsysClient.java改成这样：
package cn.edu.sjtu;
import javax.xml.namespace.QName;
import javax.xml.ws.Service;
import javax.xml.ws.soap.SOAPBinding;

public class AnsysClient {

public String execute() throws Exception {
QName serviceName = new QName("http://sjtu.edu.cn/", "AnsysService");
QName portName = new QName("http://sjtu.edu.cn/", "AnsysPort");

Service service = Service.create(serviceName);
service.addPort(portName, SOAPBinding.SOAP11HTTP_BINDING,"http://localhost:9090/AnsysPort");
cn.edu.sjtu.Ansys client = service.getPort(portName,cn.edu.sjtu.Ansys.class);
//Ansys client = new AnsysImpl();
// Insert code to invoke methods on the client here
client.init();
return client.run();
}
}
用了struts2，点了页面上一个按钮，执行action，也就是类AnsysClient中的execute方法，
struts.xml配置文件
<%@ page contentType="text/html; charset=GBK" language="java"%>
<%@taglib uri="/struts-tags" prefix="s"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=GBK"/>
<title></title>
<s:head/>

</head>
<body>
<h3></h3>
<s:form action="startClient">
<s:submit name="startClient" value="启动客户端" />

</s:form>
</body>
</html>

点了按钮后，有这样的错误：
Servlet.service() for servlet default threw exception
java.lang.NullPointerException
at com.sun.xml.internal.ws.client.WSServiceDelegate.getPortModel(WSServiceDelegate.java:570)
at com.sun.xml.internal.ws.client.WSServiceDelegate.getPort(WSServiceDelegate.java:273)

......

exception

javax.servlet.ServletException
org.apache.struts2.dispatcher.Dispatcher.serviceAction(Dispatcher.java:515)
org.apache.struts2.dispatcher.FilterDispatcher.doFilter(FilterDispatcher.java:419)

问一下是什么原因？AnsysClient.java中cn.edu.sjtu.Ansys client = service.getPort(portName,cn.edu.sjtu.Ansys.class);这一行代码有什么问题了？

从stack trace 来看你没有用CXF，用的是Sun 的JAXWS RI。
Servlet.service() for servlet default threw exception
java.lang.NullPointerException
