这个问题困扰我很久了，求大侠们帮忙看看是什么原因，感激不尽！

[samking1124]

谢谢上面各位的回答，这个是eclipse内部错误， 启动时就出这个错误，不停的刷，烦死啊

[不姓贾_请叫我甄先生]

没代码，只能说是你的程序中出现了ClassCastException是类型转换错误。你检查一下程序。

[Java技术栈]

eclipse出问题了？

先换个工作区间试试吧 file>switch workplace

[colin_pxx]

是不是你哪个类里面将实例强制转换成父类了

[jiandong3471]

是不是你的eclips的设置有问题。看一下 编译设置里的相关信息呢。

[samking1124]

问题还是没有解决 ，打开几个jsp文件 error log里就不停刷这个错误，弄得机器跑不动。
求各位大侠帮帮忙吧。。。。
