org.apache.jasper.JasperException: Unable to compile class for JSP

An error occurred at line: -1 in the jsp file: null

告诉你的已经很明显了，你不懂英语吗？都是你的jsp文件不存在了，看是不是路径错了

[ifrancis]

不要怕抛出的异常 怕的是没抛异常

[dom72]

pls ping the jsp file.

if("archive".equals(from) ) {//?ヨ?妗ｆ?绯荤?
此句中有变量没有定义：
from：是不是写错了啊？应该是form？
楼主编译没有遇到问题?
