1， 先生成java代码：
wsdl2java -d xmlbeans -uri C:\work\Helloworld.wsdl
有一个 HelloWorldServiceStub ，

方法
public  helloworld.GetGreetingsResponseDocument getGreetings(
helloworld.GetGreetingsDocument getGreetings0)
 throws java.rmi.RemoteException
{
....
....
}
2 我看了一下参数和返回值helloworld.GetGreetingsResponseDocument ,helloworld.GetGreetingsDocument都是interface


3我想做一个HelloClient调用stub的 getGreetings  ，怎么做？

附上wsdl：
