The request parameters are available on the ActionContext instance, which is made available via ThreadLocal.

Code Block
Map parameters = ActionContext.getContext().getParameters();

Preferred

Ensure that servlet-config Interceptor is included in the Action's stack.
- The default stack already includes servlet-config.
Edit the Action so that it implements the ParameterAware HttpParametersAware interface.
- The ParameterAware HttpParametersAware interface expects a setParameters method. You may wish to include a companion getParameters method.
At runtime, call getParameters to obtain a Map an object representing the request parameters.

Code Block
Map parameters = this.getParameters();

Info
When the `servlet-config` Interceptor sees that an Action implements ParameterAware, it passes a Map of the request parameters to the Action's `setParameters` method.

Tip
To unit test a ParameterAware Action, create your own Map with the pertinent request parameters and call `setParameters` as part of the test's `setUp` method.
