Class WebappUberspector

java.lang.Object
org.apache.velocity.util.introspection.UberspectImpl
org.apache.velocity.util.introspection.AbstractChainableUberspector
org.apache.velocity.tools.view.WebappUberspector
All Implemented Interfaces:
org.apache.velocity.util.introspection.ChainableUberspector, org.apache.velocity.util.introspection.Uberspect, org.apache.velocity.util.RuntimeServicesAware
public class WebappUberspector extends org.apache.velocity.util.introspection.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
