What is the standard way to handle url-mapping for JavaServer Faces?

Question

All the tutorials I have seen seem to use *.jsf, *.faces, or /<directory_name>/* for the url-pattern in the Java Server faces servlet mapping. Is there some official sun-recommended naming convention or de-facto standard?

Answer 1

The recommended conventions are in the JSF 1.2 specification.

Section 10.1.2:

When using prefix mapping, the following mapping is recommended, but not required:

<servlet-mapping>
<servlet-name> faces-servlet-name </servlet-name>
<url-pattern>/faces/*</url-pattern>
</servlet-mapping>

When using extension mapping the following mapping is recommended, but not required:

<servlet-mapping>
<servlet-name> faces-servlet-name </servlet-name>
<url-pattern>*.faces</url-pattern>
</servlet-mapping>
