服务端：
－－－－－－－－－－－－－－－－－－－
helloworld.java
public class helloworld {
public string sayhello（)
{
return "hello world! ";
}
}
改名为helloworld.jws,放到tomcat目录里。
用ie访问http://127.0.0.1:8080/axis/helloworld.jws?wsdl
可以看到xml文档。
客户端：
－－－－－－－－－－－－－－－－－－－－－－－
import org.apache.axis.client.call;
import org.apache.axis.client.service;
import javax.xml.rpc.parametermode;
public class testclient {
public static void main（string[] args) throws exception {
string endpoint = "http://127.0.0.1:8080/axis/helloworld.jws ";// 指明服务所在位置
service service = new service（); // 创建一个service实例，注意是必须的！
call call = （call) service.createcall（);// 创建call实例，也是必须的！
call.settargetendpointaddress（new java.net.url（endpoint));// 为call设置服务的位置
system.out.println（endpoint);//这里可以输出
//call.setoperationname（ "sayhello ");// 注意方法名与helloworld.java中一样！！
string res = （string)call.invoke（ "sayhello ",new object[] {});// 返回string，没有传入参数
system.out.println（res);
}
}
错误：
－－－－－－－－－－－－－－－－－－－
