高分请教"10.5.1 500 Internal Server Error"的问题
环境:weblogic6.1
页面在调用一个方法时出现下面错误:
Error 500--Internal Server Error
From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:
10.5.1 500 Internal Server Error
The server encountered an unexpected condition which prevented it from fulfilling the request.
控制台显示的信息如下:
saveQuestionAnswers
<2005-1-14 上午10时33分56秒> <Error> <HTTP> <[WebAppServletContext(2031205,pod,/pod)] Servlet failed with Exception
java.lang.NoSuchMethodError

请问是什么原因引起的?
说明一下,我在weblogic8.1上运行是正常的
