Caused by: java.lang.NullPointerException

是不是services.xml没配service？

[abcatai555]

cd.toc.Test.main(Test.java:435)
cd.toc.Test类中435行出现空指针异常，你应该用到转发器了吧，就是把客户端请求转发到服务端，转发器取到值了吗？

[xinleicn]

是不是包的问题。

谢谢 我是个新人
刚刚接手 webservice

[jackiepeng]

还是不这么明白

你请求服务端的地址可以请求到吗？
http://请求ip/工程名/web.xml中配置的名称/webservice配置文件中配置的名称?wsdl

如果在地址栏中写这个可以请求到，那说明是你客户端请求不对。
下边是客户端写法
String endpoint = "http://localhost:8090/FAP/service/UserService";
org.apache.axis.client.Service service = new org.apache.axis.client.Service();
org.apache.axis.client.Call call = (org.apache.axis.client.Call) service.createCall();
call.addParameter("name", org.apache.axis.encoding.XMLType.XSD_STRING,
javax.xml.rpc.ParameterMode.IN);
---这句是要指定你传的参数名要跟他那边需要的参数名称一样
call.setReturnType(org.apache.axis.encoding.XMLType.XSD_STRING);
---------这句是指定你参数的类型
call.setTargetEndpointAddress(new java.net.URL(endpoint));
call.setOperationName("方法名");
String res=(String)call.invoke(new Object[]{"参数","参数"});

call.setUseSOAPAction(true);
System.out.print(res);
