问题可能出在我的web.xml：

上

   <?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee"

    <servlet>

        <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？

尝试从课程@WebServlet中删除com.sdz.tp.servlets.CreationClient注释。 servlet映射可以在web.xml中定义，也可以使用注释定义，但不能同时定义。

java.lang.IllegalArgumentException：名为[X]和[Y]的servlet都映射到url-pattern [/ CreationClient]，这是不允许的
