Answer

Since the code registers a Servlet Filter, the URL pattern must conform to the URL mappings supported by Servlets/Filters, as specified in the Servlet Specification:

12.2 Specification of Mappings

In the Web application deployment descriptor, the following syntax is used to define mappings:

• 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 mapping.

• The empty string (“”) is a special URL pattern that exactly maps to the application’s context root, i.e., requests of the form http://host:port/<context-root>/. In this case the path info is / and the servlet path and context path is empty string (““).

• 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.

So, a URL can have only one wildcard, and it must be first or last:

• /some/path/*
• *.ext
