I then revive a message telling me it took longer than 45 seconds to start.
Thanks again and sorry for the massive console dump.

Answer 1

If you created a serverlet using the "Create Servlet" wizard rather than the "Create Class" wizard, the created servlet class may end up with a #WebServlet annotation which duplicates anything you may put in the web.xml.
Either you create a plain class and enter the mapping in the web xml, or you use the #WebServlet annotation, but not both otherwize there is a duplicate mapping (if you told Eclipse generates the deployment descriptor).

Answer 2

The servlets named [minkServlet] and [com.mink.web.minkServlet] are
both mapped to the url-pattern [/minkServlet] which is not permitted
Pretty much speak for itself.
You probably have two servlets mapped to the same url

Answer 3

It seems like the xml configuration contains two servlets with the same URL mapping as the stacktrace says "The servlets named [WrongServlet2] and [Wrong] are both mapped to the url-pattern [/Wrong] which is not permitted"
Have you looked into that?
