Class WebappUberspector

java.lang.Object

AbstractChainableUberspector

org.apache.velocity.tools.view.WebappUberspector

public class WebappUberspector
extends AbstractChainableUberspector

This custom uberspector allows getAttribute() and setAttribute() as standard getters and setters for the "request","session" and "application" keys.

It allows VTL statements like:

 #set($session.foo = 'youpi')
 session parameter 'foo' has value: $session.foo
 

This uberspector requires Velocity 1.6+ ; to use it, you must specify org.apache.velocity.tools.view.WebappUberspector as the last uberspector to the runtime.introspector.uberspect property in you velocity.properties file.

For instance:

runtime.introspector.uberspect = org.apache.velocity.util.introspection.UberspectImpl,org.apache.velocity.tools.view.WebappUberspector
