我们还是采用Tomcat作为web服务器，如果你对如何使用tomcat还不熟悉请参考相关资料。通常我们开发WAP应用程序的时候都是手写wml脚本，其实我们可以借助java的Servlet/jsp技术开发WAP应用程序。通常我都是使用Lomboz插件在eclipse的环境下写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);
}
}
这两个文件实现的功能是一样的，显示服务器当前的时间。我们的web.xml的内容如下：
＜?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我们可以很方便的把这个应用程序发布到tomcat的webapps目录，通过WinWap我们可以直接通过下面两个URL访问到他们
http://localhost:8088/wap/wapservlet
http://localhost:8088/wap/waptest.jsp
