jsp画面加载问题
一个测试画面,代码如下:

HTML code
<%@ page contentType = " text/html;charset=gb2312" %>  <html><head><title>Test Action</title><meta http-equiv="Content-Type" content="text/html; charset=gb2312"></head><%String  name = null;if (session.getAttribute("name")! = null ) name = ( String )session.getAttribute("name");String host = java.net.InetAddress.getLocalHost().toString();%><body><br><br><center>  The host is :<%=host %><br>  Your session id is :<%=session.getId() %><br>  Your session detail is :<%=session.toString() %><br>  Your session context is :<%=session.getSessionContext() %><br><br><%if (name! = null ){ out.print( " Your name is  " + name + "<br>" ); out.print( " The session is valid. " );}else{ out.print( " The session is invalid!!! " );}%><a href ="index.jsp">Return!</a></center></body><%if (session.getAttribute("name")! = null ) session.invalidate();%></html>

这个画面是从另外一个画面跳转过来的,第一个画面显示正常,这个画面报错,由于对jsp不是很了解,请大家指点一下!谢谢!

报错信息如下:
