4 个解决方案

#1

错误标题是  HTTP ERROR 503 其实后面还有一大堆报错信息，但是看着差不多就只复制了前面一段

库里的 standard.jar和xml-apis.jar已经删了，没用到servlet-api.jar，不知道还有没有其他冲突的jar包

本地运行正常，用到了mysql数据库，然后挂到SAE上之后就用了新浪的mysql，jdbc配置应该没问题，毕竟看到mysql里的表在程序运行后已经创建了。

求高手们赐教~~不胜感激

附上dispatcher-servlet.xml

看看配置吧
userController
好像是说，实例化urlMapping 的时候，发现 userController 这个是空指。。报空指针异常。。

查下代码，是否因为没有配置好。
