最近在學習Java EE6 ，使用NetBean 6.8和GlassFish v3進行學習開發。對Java EE6
的感覺很不錯，它屏蔽了很多細節方面的東東，方便了開發，尤其是Annotation（註解）解脫了配置XML的煩惱。我不想說Annotation多麼
多麼好，所有的技術都有其問題域，都有其觸及不到的地方，Java ,.Net 也是如此。
1.開發JAX-WS Web Service 服務端.
a.使用NetBean 建立一個Web Application
b. 建立一個Service
package server </p><p> import javax.jws.WebService;<br /> import javax.jws.webMethod; </p><p> @WebService<br /> public class Hello {<br /> private String message = new String( "Hello, " );<br /> public void Hello() {<br /> } </p><p> @WebMethod<br /> public String sayHello(String name) {<br /> return message + name + "." ;<br /> }<br />}
服務建完後，可以用NetBean提供的測試功能對其進行測試，說實在的這個功能很實用。
測試服務地址：http://localhost:8080/helloservice/HelloService?Tester
WSDL地址:http://localhost:8080/helloservice/HelloService?WSDL
2. 開發JAX-WS Web Service 用戶端
a.用NetBean建立Web Application
b.建立Web Service 用戶端
c.建立Servlet
package client; </p><p> import java.io.IOException;<br /> import java.io.PrintWriter;<br /> import javax.servlet.ServletException;<br /> import javax.servlet.annotation.WebServlet;<br /> import javax.servlet.http.HttpServlet;<br /> import javax.servlet.http.HttpServletRequest;<br /> import javax.servlet.http.HttpServletResponse;<br /> import javax.xml.ws.WebServiceRef;<br /> import ws.Hello;<br /> import ws.HelloService; </p><p> /**<br /> *<br /> * @author rywei<br /> */<br /> @WebServlet (name= "WsClient" , urlPatterns={ "/WsClient" })<br /> public class WsClient extends HttpServlet {<br /> @WebServiceRef (wsdlLocation= "WEB-INF/wsdl/localhost_8080/StudyWeb/HelloService.wsdl" )<br /> private HelloService helloservice;<br /> /**<br /> * Processes requests for both HTTP <code>GET</code> and <code>POST</code> methods.<br /> * @param request servlet request<br /> * @param response servlet response<br /> * @throws ServletException if a servlet-specific error occurs<br /> * @throws IOException if an I/O error occurs<br /> */<br /> protected void processRequest(HttpServletRequest request, HttpServletResponse response)<br /> throws ServletException, IOException {<br /> response.setContentType("text/html;charset=UTF-8" );<br /> String s="" ;<br /> if (helloservice!= null ){<br /> Hello hello=helloservice.getHelloPort();<br /> s = hello.sayHello("RenYan Wei" );<br /> }<br /> PrintWriter out = response.getWriter(); </p><p> try { </p><p> out.println("<html>" );<br /> out.println("<head>" );<br /> out.println("<title>Servlet WsClient</title>" );<br /> out.println("</head>" );<br /> out.println("<body>" );<br /> out.println("<h1>Servlet WsClient at " + request.getContextPath () + "</h1>" );<br /> out.println("<br>" );<br /> out.println(s);<br /> out.println("</body>" );<br /> out.println("</html>" ); </p><p> } finally {<br /> out.close();<br /> }<br /> } </p><p> // <editor-fold defaultstate="collapsed" desc="HttpServlet methods. Click on the + sign on the left to edit the code."><br /> /**<br /> * Handles the HTTP <code>GET</code> method.<br /> * @param request servlet request<br /> * @param response servlet response<br /> * @throws ServletException if a servlet-specific error occurs<br /> * @throws IOException if an I/O error occurs<br /> */<br /> @Override<br /> protected void doGet(HttpServletRequest request, HttpServletResponse response)<br /> throws ServletException, IOException {<br /> processRequest(request, response);<br /> } </p><p> /**<br /> * Handles the HTTP <code>POST</code> method.<br /> * @param request servlet request<br /> * @param response servlet response<br /> * @throws ServletException if a servlet-specific error occurs<br /> * @throws IOException if an I/O error occurs<br /> */<br /> @Override<br /> protected void doPost(HttpServletRequest request, HttpServletResponse response)<br /> throws ServletException, IOException {<br /> processRequest(request, response);<br /> } </p><p> /**<br /> * Returns a short description of the servlet.<br /> * @return a String containing servlet description<br /> */<br /> @Override<br /> public String getServletInfo() {<br /> return "Short description" ;<br /> }// </editor-fold> </p><p> } </p><p>
package client;import java.io.IOException;import java.io.PrintWriter;import javax.servlet.ServletException;import javax.servlet.annotation.WebServlet;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import javax.xml.ws.WebServiceRef;import ws.Hello;import ws.HelloService;/** * * @author rywei */@WebServlet(name="WsClient", urlPatterns={"/WsClient"})public class WsClient extends HttpServlet { @WebServiceRef(wsdlLocation="WEB-INF/wsdl/localhost_8080/StudyWeb/HelloService.wsdl") private HelloService helloservice; /** * Processes requests for both HTTP <code>GET</code> and <code>POST</code> methods. * @param request servlet request * @param response servlet response * @throws ServletException if a servlet-specific error occurs * @throws IOException if an I/O error occurs */ protected void processRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { response.setContentType("text/html;charset=UTF-8"); String s=""; if (helloservice!=null){ Hello hello=helloservice.getHelloPort(); s = hello.sayHello("RenYan Wei"); } PrintWriter out = response.getWriter(); try { out.println("<html>"); out.println("<head>"); out.println("<title>Servlet WsClient</title>"); out.println("</head>"); out.println("<body>"); out.println("<h1>Servlet WsClient at " + request.getContextPath () + "</h1>"); out.println("<br>"); out.println(s); out.println("</body>"); out.println("</html>"); } finally { out.close(); } } // <editor-fold defaultstate="collapsed" desc="HttpServlet methods.

在瀏覽器內開啟http://localhost:8080/WsClient/HelloServlet 進行測試
讓人頭疼的事是GlassFish v3 內不能在同一個Web Application 同時有用戶端與服務端。我建了兩個工程，A工程
是服務端，B工程是用戶端，這時能正常運行，當我在B工程裡建個服務端，要在A工程內進行調用時，就會產生錯誤，我找了很長時間也不知道是怎麼回事，望各位大俠知道的話，歡迎分享，謝謝。
錯誤如下：
