问题可能出在我的身上web.xml：

   <?xml version="1.0" encoding="UTF-8"?>

    xmlns="http://java.sun.com/xml/ns/javaee"

    <servlet>

    <servlet-mapping>
        <servlet-name>CreationClient</servlet-name>
        <url-pattern>/CreationClient</url-pattern>
    </servlet-mapping>
    <servlet-mapping>
        <servlet-name>CreationCommande</servlet-name>
        <url-pattern>/CreationCommande</url-pattern>
    </servlet-mapping>
</web-app>

有人能告诉我出了什么问题吗？

尝试@WebServlet从 class 中删除注释com.sdz.tp.servlets.CreationClient。servlet 映射可以在注释中定义web.xml或使用注释来定义，但不能同时使用两者。
