推荐答案

org.apache.jsp.getdata_005fact_jsp._jspService(getdata_005fact_jsp.java:123)

看起来您的一个JSP中有一个NullPointerException(我可以猜测页面的名称类似于fact.jsp).尝试调试您的JSP.如果您不知道，请按以下步骤操作: http://www.tutorialspoint.com/jsp/jsp_debugging.htm [^ ]

Looks like you have a NullPointerException from one of your JSPs (I can guess that the name of the page is something like fact.jsp). Try debugging your JSP. Here''s how if you don''t know: http://www.tutorialspoint.com/jsp/jsp_debugging.htm[^]
