[OmniFaces utilities (2.0)] Get the application initialization parameter map / the application initialization parameter


[OmniFaces utilities] The getInitParameterMap() method returns the application initialization parameter map. This returns the parameter name-value pairs of all <context-param> entries in in web.xml.
[OmniFaces utilities] The getInitParameter() method returns the application initialization parameter. This returns the <param-value> of a <context-param> in web.xml associated with the given <param-name>.

Method Faces#getInitParameterMap()- get the application initialization parameter map:
See also: Faces#getContext()

Method Faces#getInitParameter()- get the application initialization parameter:
See also: Faces#getContext()
Usage:

Below you can see an example of listing the content of this map:

import org.omnifaces.util.Faces;
...
Map<String, String> initmap = Faces.getInitParameterMap();
for (Map.Entry<String, String> entry : initmap.entrySet()){
     System.out.println(entry.getKey() + "/" + entry.getValue());
}

And a possible output:

org.jboss.weld.context.ignore.forward/false
resteasy.injector.factory/org.jboss.resteasy.cdi.CdiInjectorFactory
org.jboss.weld.context.ignore.include/false
javax.faces.PROJECT_STAGE/Development
resteasy.unwrapped.exceptions/javax.ejb.EJBException
org.jboss.jbossfaces.IS_CDI/true

Or, if you know the name of the desired parameter, then you can use Faces#getInitParameter():

// e.g. Development
String stage = Faces.getInitParameter("javax.faces.PROJECT_STAGE");
