run ant deploy,the webservice will be deployed in your web container.

browser:? http://127.0.0.1:8080/jaxWsTest/services/WebServiceSample?wsdl
if you see the wsdl file means the webservice is deployed successfully

3. client side:
??? There are many ways to access webservice,for instance.
??? I.? WSDL2Java generated Client
??? II. JAX-WS Proxy
? ? III. JAX-WS Dispatch APIs
??? To make it simple,we use Proxy to invoke webservice
? ? WebServiceClient.java

 
package?jax.ws.test.client;

import?java.net.MalformedURLException;

import?java.net.URL;

import?javax.xml.namespace.QName;

import?javax.xml.ws.Service;

import?jax.ws.test.WebServiceSample;

public?class?WebServiceClient?{

????public?static?void?main(String[]?args)?throws?MalformedURLException?{

????????URL?wsdlURL?=?new?URL("http://127.0.0.1:8080/jaxWsTest/services/WebServiceSample?wsdl");

????????QName?SERVICE_NAME?=?new?QName("http://test.ws.jax/",?"WebServiceSampleImplService");
????????Service?service?=?Service.create(wsdlURL,?SERVICE_NAME);

????????WebServiceSample?client?=?service.getPort(WebServiceSample.class);

????????String?result?=?client.say("kaven");????

????????System.out.println("Response?from?server?:?"+result);
????}
}

?? 4. Advanced Tech
??? ??? I. Configure the client invoking ConnectionTimeout and ReceiveTimeout

 
 ????????Client?client?=?(Client)?ClientProxy.getClient(port);
????????HTTPConduit?http?=?(HTTPConduit)?client.getConduit();

????????HTTPClientPolicy?httpClientPolicy?=?new?HTTPClientPolicy();
????????httpClientPolicy.setConnectionTimeout(300);? // set ConnectionTimeout

????????httpClientPolicy.setAllowChunking(false);
????????httpClientPolicy.setReceiveTimeout(3200);? // set ReceiveTimeout
????????http.setClient(httpClientPolicy);

??? ???more info refer to :http://cwiki.apache.org/CXF20DOC/client-http-transport-including-ssl-support.html
??
??? ??? II.? 那么多的jar包，是不是很晕呢，刚才花了几个小时，终于找到了Java客户端调用CXF Web-Service最小Jar包子集。
??? ?? ? ??? ?

?????? ? ? ? ? ??? ?? ??? ???? 图中所示的都是必要的，缺一不可，如果是standalone那么jboss下的两个必要的，如果在Jboss container中，可以不要 ??? ????? ??? ?? ? ??? III. Asynchronous WebService Calling ???
