You didn't post your mappings?

Looking at:

already exists at node ...


makes me wonder if you have a duplicate mapping.

I know that the original posters may not be interested anymore but I was also getting the same error message.
In looking at the web.xml, I noticed that my servlet had multiple servlet-mapping elements for the same servlet and the url-patterns only differed by a forward slash. See the example below:
<servlet-mapping>
<servlet-name>ServletName</servlet-name>
<url-pattern>entry</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>ServletName</servlet-name>
<url-pattern>/entry</url-pattern>
</servlet-mapping>
During the startup the container saw the above entries as duplicates and threw that exception.
Hope this helps someone, someday.

I am having the same error. I do use the same url pattern twice mapping to two total different servlets. I am wondering if this is causing the problem.
Please post the solution to this topic.

In web.xml i have the below enteries but it gives the same mapping clash exception
<servlet-mapping>

<servlet-name>assigncorrectspelling</servlet-name>

<url-pattern>/assigncorrectspelling</url-pattern>

</servlet-mapping>

<servlet-mapping>

<servlet-name>assigncorrectspelling1</servlet-name>

<url-pattern>/assigncorrectspelling</url-pattern>

</servlet-mapping>



<servlet>

<servlet-name>assigncorrectspelling</servlet-name>

<display-name>assigncorrectspelling</display-name>

<jsp-file>/jsp/synonymmaintenance/assigncorrectspelling.jsp</jsp-file>

</servlet>

<servlet>

<servlet-name>assigncorrectspelling1</servlet-name>

<display-name>assigncorrectspelling</display-name>

<jsp-file>/jsp/synonymmaintenance/assigncorrectspelling.jsp</jsp-file>

</servlet>


Kindly help

I am also facing the same error . I cross verified my web.xml and it doesnt have 2 entries for the same servlet, but still it keeps giving the following error. Looks like the entry is present in some archive file within the RSA internal folder...not sure how to get rid of this
