@Override
public String execute() throws Exception {

    ActionContext aContext = ActionContext.getContext();           


        

Answer 1

Parameters are always use a type Map. And you need to put parameter correctly, i.e.

aContext.getParameters().put("reqVar1", new String[] {"reqVar1-Value"});

and get correctly, i.e.

The better approach is to use params interceptor that is included in thedefaultStack to populate parameters from the request.
