Oh, well, that works just great if you use the WebWork framework., get the CVS 'coz the Velocity
integration is hot off the press.

Simple WebWork tutorial follows.

Write code like this:
public class MyAction
  implements Action
  String someData;
  public String execute()
    someData = "World";
    return SUCCESS;

  public String getData()
    return someData;
add a controller/view mapping into like this:

and write a template (myaction.vm) like this:
Hello $data

and watch "Hello World" being generated.

That's it. Pretty straightforward. Add whatever data you want in your
Action, or use action chaining, i.e. let "myaction.success" point to
another action which can add more data to be accessible.

I'm working on the integration to make it as smooth as possible, but the
current CVS should be ok.
