Action and Pull Service

[John Davis <jo...@bellsouth.net>]

Within a VelocityAction class I am trying to dynamically load classes that implement an interface with an execute() method. How do I utilize the pull service so that I can access session and request scope data within these classes? 
For example:

public interface LoadClass
{
    public void execute();
}

public class LoadClassImpl implements LoadClass
{
   public LoadClass(){}
   public void execute()
   {
      // how do I access session and request data in this method
   }
}

public class MyAction extends VelocityAction
{
   public void doPerform(RunData data, Context context) throws Exception
   {
      LoadClass c = (LoadClass) Class.forName("LoadClassImpl").newInstance();
      c.execute();
   }


Any help would be appreciated.

How about:

public interface LoadClass
{
  public void execute(RunData data, Context context);
}

or:

  public void setContext(RunData data, Context context);

then call execute() after having setContext().

If you can't modify the LoadClass interface, must only guess would be
some kind of thread-context ... but that's out of my range of
experience. It's only a guess.
