The problem is probably with my web.xml:
问题可能出在我的web.xml：

Could someone tell me what's wrong?
有人能告诉我出了什么问题吗？

Try removing the @WebServletannotation from class com.sdz.tp.servlets.CreationClient. The servlet mapping can be defined either in web.xmlor using an annotation, but not both.
尝试@WebServlet从 class 中删除注释com.sdz.tp.servlets.CreationClient。servlet 映射可以在web.xml注释中定义或使用注释定义，但不能同时定义。
