[OmniFaces utilities (2.0)] Get faces servlet mapping


[OmniFaces utilities] The getMapping() method determines and returns the faces servlet mapping used in the current request. If JSF is prefix mapped (e.g. /faces/*), then this returns the whole path, with a leading slash (e.g. /faces). If JSF is suffix mapped (e.g. *.xhtml), then this returns the whole extension (e.g. .xhtml).

[OmniFaces utilities] The isPrefixMapping() method returns whether the faces servlet mapping used in the current request is a prefix mapping.

Method:

For JSF, the faces servlet mapping is specified in web.xml file as below (several common cases):

·         without prefix mapping (with suffix mapping, *.xhtml)

<servlet-mapping>
 <servlet-name>Faces Servlet</servlet-name>
 <url-pattern>*.xhtml</url-pattern>
</servlet-mapping>

·         common prefix mapping (e.g. /faces/*).

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

·         un-common prefix mapping (e.g. /797b/*).

<servlet-mapping>
 <servlet-name>Faces Servlet</servlet-name>
 <url-pattern>/797b/*</url-pattern>

</servlet-mapping>

Usage:

import org.omnifaces.util.Faces;
...
String mapping = Faces.getMapping(); //e.g. prefixes: /faces, /797b
                                            suffixes: .xhtml
or,

import static org.omnifaces.util.Faces.getMapping;
...
String mapping = getMapping(); //e.g. prefixes: /faces, /797b
                                            suffixes: .xhtml

OmniFaces also comes with an OmniFaces utilities that returns true if the faces servlet mapping used in the current request is a prefix mapping. This OmniFaces utilities is named, isPrefixMapping():

Method:
Usage:

import org.omnifaces.util.Faces;
...
// e.g. for '/faces', '/797b' it returns true, while for '.xhtml' suffix, it will return false
boolean isprefix = Faces.isPrefixMapping();

or,

// e.g. for '/faces', '/797b' it returns true, while for '.xhtml' suffix, it will return false
import static org.omnifaces.util.Faces.isPrefixMapping;
...
boolean isprefix = Faces.isPrefixMapping();
