public class SessionPropagatorAction
extends AbstractConfigurableAction
implements ThreadSafe

This is the action used to propagate parameters into session. It simply propagates given expression to the session. If session does not exist, action fails. Additionaly it will make all propagated values available via returned Map.

 <map:act type="session-propagator">
      <paramater name="example" value="{example}">
      <paramater name="example1" value="xxx">
 </map:act>

Method Detail

configure

public void configure(Configuration conf)
               throws ConfigurationException

Description copied from class: AbstractConfigurableAction

Configures the Action. Takes the children from the Configuration and stores them them as key (configuration name) and value (configuration value) in settings.
This automates parsing of flat string-only configurations. For nested configurations, override this function in your action.

Specified by:

configure in interface Configurable

Overrides:

configure in class AbstractConfigurableAction

Throws:

ConfigurationException

act

public Map act(Redirector redirector,
               SourceResolver resolver,
               Map objectModel,
               String src,
               Parameters parameters)
        throws Exception

Main invocation routine.

Specified by:

act in interface Action

resolver - The SourceResolver in charge

objectModel - The Map with object of the calling environment which can be used to select values this controller may need (ie Request, Response).

src - A source String to the Action

parameters - The Parameters for this invocation

Returns:

Map The returned Map object with sitemap substitution values which can be used in subsequent elements attributes like src= using a xpath like expression: src="mydir/{myval}/foo" If the return value is null the processing inside the element of the sitemap will be skipped.

Throws:

Exception - Indicates something is totally wrong
