login.jsp登录页面
jsp页面的验证功能还没实现好，我先忽略掉了。

<html>
<head>
<title>用户登录</title>
<scripttype="text/javascript">
functionrefresh()
{
varimg=document.getElementById("img_validation_code");
img.src="validate_code.action?"+Math.random();
}
</script>
</head>
<body>

用户名：<inputtype="text"name="username"/>
密码：<inputtype="password"name="userpwd"/>

TestSql1.java这里处理jsp发过来的参数数据库用DBUtils来处理的
packagecom.dao;
importjava.sql.SQLException;
importcom.DB.DBUtils;
importcom.opensymphony.xwork2.ActionSupport;
publicclassTestSql1extendsActionSupport
{
publicTestSql1()
{}
privateStringusername;
privateStringuserpwd;
publicStringsuccess;
publicStringgetUsername()
{
returnusername;
}
publicvoidsetUsername(Stringusername)
{
this.username=username;
}
publicStringgetPwd()
{
returnuserpwd;
}
publicvoidsetPwd(Stringuserpwd)
{
this.userpwd=userpwd;
}
publicbooleanadduser(Stringparams[])throwsSQLException
{
intresult=-1;
result=DBUtils.DBOperationUpdate("insertintot_uservalues(?,?)",params);
returnresult>0;
}
publicStringexcute()throwsSQLException
{
Stringparams[]={username,userpwd};
if(adduser(params))
{
return"success";
}
return"success";
}
}
以防万一问题可能出现在web.xml（个人觉得应该跟web.xml没什么关系）
有点多乱啊

感觉错误跟importcom.DB.DBUtils;没关系就先不贴了
下面是login.jsp提交后出现的页面，
下面是lib下的jar包
struts.xml配置应该没问题呀，而且包应该也齐了呀，实在不知道问题出在哪里了
------解决思路----------------------
404,一般都是路径错，很明显你的adduser找不到，TestSql1的mapping在哪里？
------解决思路----------------------
用struts2你不用struts2的那个filter么
