All Implemented Interfaces:
Interceptor

This interceptor populates the action with the static parameters defined in the action configuration. If the action implements Parameterizable , a map of the static parameters will be also be passed directly to the action.

Parameters are typically defined with <param> elements within xwork.xml.

Interceptor parameters:

None

Extending the interceptor:

There are no extension points to this interceptor.

Example code:


<action name="someAction" class="com.examples.SomeAction">
<interceptor-ref name="staticParams">
<param name="parse">true</param>
</interceptor-ref>
<result name="success">good_result.ftl</result>
</action>
