Introduction

+
+

Prerequisites

+
+ +

Question: Do you know what Lifecycle in Avalon is? Ok, start reading.

-

TBD

+

If not, look at Egg and understand this concept before reading about Containers.

+ + +
+

Do I really know what a Container is?

+ +

Well, you're mostly on your own for now. We're still working + on the entire concept of container and on the various containers + that ship with avalon.

- -

TBD

+

Anyway, Tweety.java conceptually is a Container. Look at the difference between + Tweety and Egg, and you'll see that the main difference are: + +

+
    + +
  • Egg has just main(), while Main calles Tweety, ie The application (Main) uses the container (Tweety)
    • + +
  • Tweety is a Container but also a Component; this is important, because it could contain + itself hierarchically.
    • + +
+
+ + +

+ + + +
+

So you want to build your won container, huh?

+ + +

For now, I suggest you check out the sources for Tweety + (inside the jakarta-avalon-excalibur CVS module), + Plexus, + Containerkit (also inside the jakarta-avalon-excalibur + CVS module), Fortress (same CVS module) and Phoenix + (inside the jakarta-avalon-phoenix CVS module) to see + how it is done.

+ + +

Finally, take a peak at the avalon-dev mail archives or ask some + questions on that list,

TBD

+ + +

There's quite a few things different about this component compared to the BirdSong1 class. + The constructor doesn't take any arguments; those are passed in at a later point instead through + the use of parameterize(). sing() has been renamed to start(), and a stop() method has been + added. Also, logging statements have been added throughout the code. Finally, the + actual printing of the messages is handled in a separate thread.

+ + +

All the added complexity is of course not really justified for this simple demo component; it + just serves to illustrate typical evolution from an 'average' java class into a typical avalon + component.

Why tweety?

+
+

Why tweety?

+

Some people found avalon very complex to get started with. We decided a good way to fix this was to provide an implementation specifically geared at learning how avalon works: tweety.

+ +
+

Why name an avalon container 'tweety'???

+ +

"No clues in this fishy. No clues in that fishy."
+
+ One popular avalon subproject (also a container) is called Phoenix. It has quite a + lot of features (runs multiple applications, classloader management, isolation, + automagically provides management for hosted applications, etc etc etc). It is also + quite difficult to get started with at first.
+ "Phoenix" (among other things) is the name of a powerful mythological bird. Tweety + is the name of a sweet yellow canary. Some of us geeks think it is funny.

"Gimme a 'P', gimme a 'U', gimme a 'D', 'D', 'Y'."
+
+ Very unlikely. That would probably increase tweety in size and complexity, which we don't want.

+ +
+

My question is not answered. What do I do?

+
+ +

"Oh goody, goody. A surprise for me."
+
+ Start by reading the documentation provided. If your question is not answered + there, post a detailed message to the + Avalon User list. + We will try to help you out.

+ + +
+

I followed the instructions in the getting started document, but Tweety doesn't work. What do I do?

+
+ +

"Aaaah. The poor puddy tat fall down."
+ That's not supposed to happen! Please contact us through the user mailing list + (see above) with detailed information of your system configuration and what steps + you took that led to an error message, and of course the error message.

+ + +
+

Knock it off with the stupid quotes already!!!

+ +

"I did! I did taw a puddy tat!"
+
+ You can find a lot more, along with pictures, icons, sounds, animations, what + have ye, just by typing "tweety" into the google search box. Just in case you + came here looking for just that, + this site + will get you started. + In case you really can't stand it, go and read our serious documentation about + multi-dimensional separation of concerns 'n stuff!

The one feature that Tweety has as opposed to related avalon projects is that it is simple, simple, simple. Following the getting started document should get you running tweety in about 2 minutes, and developing components in 10.

- + +
+

Egg

+ +

Tweety is small and easy, but it can be made easier still.

+ +

For real starters there is Egg, that introduces you to the Lifecycle + concept. Once you understand it hatch, it's time to Chirp!

+ + +
+

Tweety

+
+ +

Then Tweety awaits you, and introduces the concept of a Container.

+ +

It can't be simpler, one concept at a time!

    -Very simple container for avalon components, written for educational purposes. -Tweety is not intended for use in production environments, though there is -nothing preventing you from using it for that purpose. -

    - -

    Goals

    -
  • be well documented
    • -
  • provide full support for the avalon framework interfaces
    • -
  • provide support for nothing else
    • -
  • use default framework implementations where possible
    • -
  • sacrifice flexibility for readable code wherever possible
    • -
  • sacrifice reusability for readable code wherever possible
    • -
  • use the most simple configuration possible
    • -
  • support only minimal metainfo (for example, no dependency mapping)
    • -
  • no security
    • -
  • minimal thread management
    • -
  • no classloader management
    • -
  • separation of engine and (mainable) embeddor
    • - -

    Use Case

    -

    An example of an avalon container for simple components, to use in -teaching avalon concepts.

    +

    Tweety is a minimalist container explicitly designed for educational purposes, and +educational purposes only.

    + + +

    In other words, if you want to learn the concepts behind avalon, and see some examples +of how to apply them, tweety is your starting point. If you need to actually write really +cool components for a production environment, look elsewhere.

    This is a stripped down and collapsed version of Tweety combined with Main. It reads the configuration file, and creates the components. Then it disposes them.

    Useful to understand what Lifecycle is, without getting yet into what a Container is; this is application+Container all in one.

    After you understand this, look at Main and Tweety.

    note: Egg does not support the contextualize(), configure() or parameterize() lifecycle stages.

    Constructor Detail

    Main

      protected Main()
    We've marked the constructor as protected to prevent instantiation. Main is not a real 'object' or 'component', but rather a container for some procedural code (inside the main() method). There is no need to create an instance of it.

    Method Detail

    main

      public static void main(String[] args)
    This method is called to invoke Tweety from the command line; It instantiates a new Tweety instance, provides the parameters to configure tweety by loading them from a file, and then runs tweety itself through its lifecycle.

    Note: we should improve this method to create a sensible context and configuration for hosted components.

    Parameters:
    args - the command line arguments. We don't use them.
