Learning Java 6 (1) WebServices (1) Server

Java 6 was released. One of the new features that attracted me was the native support for WebServices. I would like to share my learning experience with you here.
The following describes the simplest WebServices: Package org. hermit. Study. JDK;

Import javax. JWS. webmethod;
Import javax. JWS. WebService;
Import javax. JWS. Soap. soapbinding;

@ WebService (targetnamespace = "http://jdk.study.hermit.org/client ")
@ Soapbinding (style = soapbinding. style. RPC)
Public class Hello {
@ Webmethod
Public String sayhello (string name ){
Return "Hello:" + name;
}
}

How can it be concise? Many of my friends still need to execute "wsgen-CP. <path>" in the command line"
Services written in this way can save the above steps.

Targetnamespace = "http://jdk.study.hermit.org/client" specifies the class path that the client stores after obtaining the server service. Note that http: // jdk.study.hermit.org/clientwill be placed under org.hermit.study.jdk.client.
The following is the release service: Package org. hermit. Study. JDK;

Import javax. xml. ws. endpoint;

Public class startservice ...{
Public static void main (string [] ARGs )...{
Endpoint. Publish ("http: // localhost: 8080/helloservice", new Hello ());
}
}

It's more concise. Just a word.
Http: // localhost: 8080/helloservice refers to the published address.

Run startservice... and enter http: // localhost: 8080/helloservice in the development browser? WSDL
