来源：互联网发布：ie不能登录淘宝网编辑：程序博客网时间：2024/05/16 15:27

文件准备：JDK、Myeclipse8.6、tomcat6.0

1、jdk1.6和Myeclipse8.6的安装，解压tomcat

2、配置JDK的环境变量，Tomcat环境变量无需指定

系统变量→新建 JAVA_HOME 变量。变量值填写jdk的安装目录（例如 E:\Java\jdk1.7.0)

系统变量→寻找 Path 变量→编辑 %JAVA_HOME%\bin;%JAVA_HOME%\jre\bin;

系统变量→新建 CLASSPATH 变量 .;%JAVA_HOME%\lib;%JAVA_HOME%\lib\tools.jar（注意最前面有一点）

测试：cmd 输入 java -version

3、为Myeclipse8.6指定jdk1.6和Tomcat6.0的运行环境

Preferences/Java/Installed JREs/Add进行添加

Preferences/MyEclipse Enterprise Workbench/Servers/Tomcat，选择对应版本进行添加

4、新建javaweb工程测试连通性，http://localhost:8080

5、关闭html,jsp等页面的可视化编辑器

preferences-> General-> Editors -> File Associations在上方框内选择*.jsp（或*.html），在下方框内选择MyEclipse JSP Editor（或MyEclipsehtml Editor），按Default即可。

6、Servlet、Jsp模版修改（可用EditPlus修改）

Servlet修改: 找到MyEclipse安装目录下的\Common\plugins文件夹，比如：D:\MyEclipse10\Common\plugins\com.genuitec.eclipse.wizards_9.0.0.me201108091322.jar\templates\Servlet.java

模版代码：

#---------------------------------------------#
# <aw:description>Template for Servlet</aw:description>
# <aw:version>1.1</aw:version>
# <aw:date>04/05/2003</aw:date>
# <aw:author>Ferret Renaud</aw:author>
#---------------------------------------------#

<aw:import>java.io.IOException</aw:import>
<aw:import>java.io.PrintWriter</aw:import>

<aw:import>javax.servlet.ServletException</aw:import>
<aw:import>javax.servlet.http.HttpServlet</aw:import>
<aw:import>javax.servlet.http.HttpServletRequest</aw:import>
<aw:import>javax.servlet.http.HttpServletResponse</aw:import>

<aw:parentClass>javax.servlet.http.HttpServlet</aw:parentClass>

<aw:method name="doGet">
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {

}

</aw:method>

<aw:method name="doPost">

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

</aw:method>

Jsp修改：（删除部分）

D:\MyEclipse10\Common\plugins\com.genuitec.eclipse.wizards_9.0.0.me201108091322.jar\templates\jsp\jsp.vtl

#*---------------------------------------------#
# Template for a JSP
# @version: 1.2
# @author: Ferret Renaud
# @author: Jed Anderson
#---------------------------------------------#
*#<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>

<title>My JSP '$title' starting page</title>

</head>

<body>
This is my JSP page. <br>
</body>
</html>

7、数据库的安装
