10.2 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 '/*' postfix is used as a path
mapping.
• A string beginning with a '*.' prefix is used as an extension mapping.
• All other strings are used as exact matches only
•
A string containing only the '/' character indicates that servlet
specified by the mapping becomes the "default" servlet of the
application.
For example, a web.xml
file for the examples
context on the server at example.com
matches the pattern in <url-pattern>/status/*</url-pattern>
as follows:
|
http://example.com/examples/status/synopsis |
Matches |
|
http://example.com/examples/status/complete?date=today |
Matches |
|
http://example.com/examples/status |
Matches |
|
http://example.com/examples/server/status |
Does not match |
A context located at the path /examples
on the server at example.com matches the pattern in <url-pattern>*.map</url-pattern>
as follows:
|
http://example.com/examples/US/Oregon/Portland.map |
Matches |
|
http://example.com/examples/US/Washington/Seattle.map |
Matches |
|
http://example.com/examples/Paris.France.map |
Matches |
|
http://example.com/examples/US/Oregon/Portland.MAP |
Does not match, the extension is uppercase |
|
http://example.com/examples/interface/description/mail.mapi |
Does not match, the extension is mapi rather than map |
