jsp语句出错,equals的用法!请指点,谢谢!

if (request.getParameter("RadioGroup1").equals("add"))请高人指点！出错信息不在这语句，但注释后程序正常！

我今天在别的机器上试过了,我的程序没有问题啊!应该是我的tomcat有问题了,我将出错码贴出来了,请大家帮下小弟!
源码:
出错码:

.....后面由于字数所限贴不出来了

你最好把程序的其他部分也贴上来，好让我帮你自习分析下，光看这句是看不出错误的。

你好！ 改成这个试下String(request.getParameter("RadioGroup1")) 我的回答你还满意吗~~
