in your action mapping for the controller then you just declare the
action forward for the state.


	<action-mappings>
		<!-- Browse Forum Messages -->
		<action path="/eforum/Browse"
			type="com.jcorporate.eforum.controller.Browse"
			name="browseForm"
			scope="session"
			validate="false" >
			<forward name="promptSelGroups" path="/expresso/components/eforum/jsp/groups.jsp"/>
			<forward name="promptGroupSubscribe" path="/expresso/components/eforum/jsp/subscribe.jsp"/>


The name of the forward matches the state name in the controller.
For example  "promptGroupSubscribe" is the state name, which is
in reality is the method

`protected void runPromptGroupSubscribeState( .... ) { ... }'

So all you have to do is carefully match the names.
