(三) 配置struts2.0
这里使用Struts2.0。加载5个struts包，调试配置struts action并测试tomcat指向war文件夹，并通过。

- commons-fileupload-1.2.1.jar
- commons-logging-1.0.4.jar
- commons-logging-api-1.1.jar
- freemarker-2.3.13.jar
- ognl-2.6.11.jar
- struts2-core-2.1.6.jar
- xwork-2.1.2.jar

这里不赘述：
把相关配置和程序代码附上：
web.xml

struts.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC

<action name="teststruts" class="com.test.struts.StrutsTestAction">
<result name="success">teststrutstarget.jsp</result>
</action>
</package>
</struts>

StrutsTestAction.java

package com.test.struts;

import com.opensymphony.xwork2.ActionSupport;

public class StrutsTestAction extends ActionSupport{

/** serialVersionUID: long 成员描述：TODO */
private static final long serialVersionUID = 1L;

private String username;
@Override
public String execute(){
String username = getUsername();
username += " is just request!";
setUsername(username);
return SUCCESS;
}
/**
* @return the username
*/
public String getUsername() {
return username;
}
/**
* @param username the username to set
*/
public void setUsername(String username) {
this.username = username;
}
}

teststruts.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>struts test</title>
</head>

<body>
<s:form action="teststruts">
<s:textfield name="username" label="User Name"></s:textfield>
<s:submit></s:submit>
</s:form>
</body>
</html>

teststrutstarget.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>test struts target</title>
</head>

<body>
<s:property value="username"/>
</body>
</html>

测试jsp，通过，代表struts配置完毕。

OK，我们开始尝试让gwt host的调试模式直接访问tomcat。以便能够联通调试前台与后台，否则如果不能联通，那gwt的意义就会大打折扣。
