using alternative views

[Mark Lybarger <Ma...@CBC-Companies.com>]

Is it possible to use java applets as the view portion of my TDK web app?
Know where I could find a good start on some reading material on the
subject?

Well, sort of. If you don't want to use "Java applets" but java
classes, then Turbine can help you.

If you don't configure a template service (or even if you do :-) ),
you can back every screen, layout and page with a java class which
gets called if you request a certain template. There you can put java
code to generate your output.

Try putting

modules.packages = org.apache.turbine.modules, com.yourcompany.modules

into your TR.properties and then write a class

package com.yourcompany.modules.screens;

import org.apache.turbine.modules.Screen;

public class Myscreen extends Screen
{
  public ConcreteElement doBuild(RunData data)
  {
    ConcreteElement ce = new StringElement();
    ce.addElement("Hello World");
    return ce;
  }
}

and request

...your turbine url../screen/MyScreen

which should execute the doBuild() of that class above and render
it in a (possible Template) layout.

If you don't run a template service at all (remove it from TR.props),
you might need a page class which could extend DefaultPage and maybe a
layout class (if you don't have one, the page class will render the
screen directly).

(Hm, we might want to have a default page and layout class which is
used if we don't use a template service but want to render the output
of a class.)
