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.
