eclipse开发structs 异常

elipsejuno开发struts2:

1.新建一web工程

工程右键属性添加扩展struts2jar包并不能部署到文件引用上。

2.在WebContent下的WEB-INF目录下的lib目录上导入struts2的lib下的JAR包。这样却可以部署到文件引用上。【在myEclipse上直接工程右键添加JAR包即可】

3.在WebContent下新建一个JSP首页文件：request.getContextPath()获取根目录地址；*.do映射到web.xml的<servlet>配置

<body>
<form action=" <%=request.getContextPath() %>/login.do " method="post">
         username:<input type="text" name="name" /><br>
   password:<input type="password" name="password" /><br>
   <input type="submit" value="login"><br>
   request.getContextPath()<input type="text" name="name" value=<%=request.getContextPath()%> /><br>
</form>
</body>
