源代码没有错误在j2ee sdk中部署是可以运行的，在tomcat下就有错误了,代码中用到了数据库连接，sqlserver2000。

Posted by: bluebe Posted on: 2005-05-10 22:42 放到WEB-INF下面（classes or lib）

Posted by: t1031 Posted on: 2005-05-14 14:19 我搞定了只要在每个javabean文件的最前面加上package语句就行了，如果class文件直接放在classes下面，jsp会找不到class文件的，如果在classes下面另建一个文件夹，把class文件放到里面就可以了
