我們還是采用Tomcat作為web服務器，如果你對如何使用tomcat還不熟悉請參考相關資料。通常我們開發WAP應用程序的時候都是手寫wml腳本，其實我們可以借助java的Servlet/jsp技術開發WAP應用程序。通常我都是使用Lomboz插件在eclipse的環境下寫servlet/jsp文件的。先看下面的waptest.jsp文件和WapServlet.java文件

＜?xml version="1.0"?＞
＜!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN"
"http://www.wapforum.org/DTD/wml_1.1.xml"＞
＜%
response.setContentType("text/vnd.wap.wml");
out.println("＜wml＞");
out.println("＜card title="MobileDate"＞");
out.println(" ＜p align="center"＞");
out.println("Date and Time Service＜br/＞");
out.println("Date is: "+ new java.util.Date());
out.println("＜/p＞");
out.println("＜/card＞");
out.println("＜/wml＞");
%＞

package com.j2medev.mingjava;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class WapServlet extends HttpServlet
{

protected void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException
{

response.setContentType("text/vnd.wap.wml");

PrintWriter out = response.getWriter();

out.println("＜?xml version="1.0"?＞");
out.println("＜!DOCTYPE wml PUBLIC"-//WAPFORUM//DTD WML 1.1//EN"");
out.println(""http://www.wapforum.org/DTD/wml_1.1.xml"＞");
out.println("＜wml＞");
out.println("＜card title="MobileDate"＞");
out.println(" ＜p align="center"＞");
out.println("Date and Time Service＜br/＞");
out.println("Date is: " + new java.util.Date());
out.println("＜/p＞");
out.println("＜/card＞");
out.println("＜/wml＞");

}

protected void doPost(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException
{
doGet(request,response);
}
}

這兩個文件實現的功能是一樣的，顯示服務器當前的時間。我們的web.xml的內容如下：

＜?xml version="1.0" ?＞
＜!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd"＞
＜web-app＞
＜servlet＞
＜servlet-name＞WapServlet＜/servlet-name＞
＜servlet-calss＞com.j2medev.mingjava.WapServlet＜/servlet-class＞
＜/servlet＞
＜servlet-mapping＞
＜servlet-name＞WapServlet＜/servlet-name＞
＜url-pattern＞/wapservlet＜/url-pattern＞
＜/servlet-mapping＞
＜welcome-file-list＞
＜welcome-file＞index.jsp＜/welcome-file＞
＜/welcome-file-list＞

＜error-page＞
＜error-code＞404＜/error-code＞
＜location＞/error.jsp＜/location＞
＜/error-page＞

＜/web-app＞

使用Lomboz我們可以很方便的把這個應用程序發布到tomcat的webapps目錄，通過WinWap我們可以直接通過下面兩個URL訪問到他們

http://localhost:8088/wap/wapservlet
http://localhost:8088/wap/waptest.jsp
