关于jsp+tomcat7.0的问题

fstao 2012-12-28 05:46:30

我已经配置好了tomcat7.0，在ie里录入：http://localhost:8080/，出来是正常的界面，说明配置没有问题了。由于我把tomcat7.0是用安装程序，安装在c盘的，如“C:\Program Files\Apache Software Foundation\Tomcat 7.0”，我在webapps里增加了文件夹：myapp,在mayapp文件夹下增加WEB-INF的文件夹，在WEB-INF下增加一个文件“web.xml”，代码如下：

<?xml version="1.0" encoding="gb2312"?>

<web-app>

<display-name>My Web Application</display-name>

<description>

A application for test

</description>

</web-app>

我又在myapp的目录下增加一个"index.jsp"，代码如下：

<html>

<body>

<center>Now time is: <%=new java.util.date()%></center>

</body>

</html>

我重启了tompcat7.0，我在ie地址录入：http://localhost:8080/myapp/index.jsp，回车出现错误：

HTTP Status 500 - Unable to compile class for JSP:

messageUnable to compile class for JSP:

请问是什么问题？如何解决？
