java.lang.IllegalArgumentException: The servlets named [X] and [Y] are both mapped to the url-pattern [/CreationClient] which is not permitted

Question

I can not start Tomcat: Server Tomcat v7.0 Server at localhost failed to start.

Caused by: java.lang.IllegalArgumentException: The servlets named [CreationClient] and [com.sdz.tp.servlets.CreationClient] are both mapped to the url-pattern [/CreationClient] which is not permitted

The problem is probably with my web.xml:

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

Could someone tell me what's wrong?

Try removing the @WebServlet annotation from class com.sdz.tp.servlets.CreationClient. The servlet mapping can be defined either in web.xml or using an annotation, but not both.

Thanks. I have tried but now i have an error 404! – user3161023 Jan 04 '14 at 23:23
Then it's a different problem. I suggest you ask a new question with the details, e.g. which URL you are calling. – David Levesque Jan 04 '14 at 23:39
How can i join an zip of my project please? – user3161023 Jan 04 '14 at 23:52
You can't. You should include the parts of your code that are significant to the problem in the question text. See also http://sscce.org/ – David Levesque Jan 04 '14 at 23:57
+1 for right ans dude :) – Kishan Bheemajiyani May 22 '14 at 19:30
This error usually occurs in case of wrong XML file. Either its web.xml or context.xml. – ManojP Dec 16 '14 at 13:36
