查了下Servlet.service() for servlet jsp threw exception
这个错误说可能是因为form中的method没有选 还有conn=null但是我这个页面都没有
能否看到错误在哪行?

------解决方案--------------------
java.lang.ArrayIndexOutOfBoundsException: 7
数组越界 


jsp文件出错吧？
------解决方案--------------------
这是个很明显的数组越界异常，建议LZ仔细检查一下

leftpage.jsp文件出问题了，你把其中的java代码，依次注释看看，看错误在哪。
