java.lang.IllegalArgumentException: Invalid in servlet mapping


The URL pattern is not valid. It can either end in an asterisk or start with one (to denote a file extension mapping).

The url-pattern specification:

  • A string beginning with a ‘/’ character and ending with a ‘/*’
    suffix is used for path mapping.
  • A string beginning with a ‘*.’ prefix is used as an extension
  • A string containing only the ’/’ character indicates the “default”
    servlet of the application. In this
    case the servlet path is the request
    URI minus the context path and the
    path info is null.
  • All other strings are used for exact matches only.

See section 12.2 of the Java Servlet Specification Version 3.1 for more details.
