求助！访问JSP页面时出现HTTP Status 500错误，不知道是什么原因，希望高手指点

在从 Action类迁移到JSP页面的时候出现了如下错误，HTTP Status 500 -type Exception reportmessagedescription The server encountered an internal error () that prevented it from fulfilling this request.exceptionorg.apache.jasper.JasperException: Unable to compile class for JSPGenerated servlet error:

          if (_jspx_meth_html_hidden_2(_jspx_th_html_form_0, _jspx_page_context))后面还有很多，一般出现这样的错误是什么原因呢？？
