[JBoss-user] [Microcontainer] - Re: How to access beans created by the bootstrap
I know this thread is now old and that I haven't post anything but my work took
me away from JBoss Microcontainer for a while But finally, I understand
what Adrian meant in his examples, and why there is no "getBean()". The whole
idea is quite simple, but given the fact that I had hard time with it, maybe
other will, so i'll explain here what i finally understood.
Basicly my question was "how can i get my bean from the bootstrap in a simple
"main' program ?" . In a small spring app, i would have done this :
| public class MyApp
| {
| public static void main(String[] args)
| {
| ...
| Component comp = context.getBean("component');
| }
| }
When i look at JBoss Container documentation and examples, i was looking for
this kind of behavior. A method to call, something where my program could
actually use the 'created bean'. And there I was wrong. As Adrian stated, the
use of a '.getBean' method ruins the all concept of IoC as it tie the program
to a specific API ( in this case Spring API).
I agreed ( and i still agree) but i didn't see how to do without it, even when
i look into the example. Then, it finally struck me ( i know, i know i'm quite
slow) : There is actually no need for my program to get beans from the
microcontainer as my program is another bean managed by the container. At the
bootstrap , the microcontainer will create my program and execute its
initialisation method ( or simply its constructor) and there the program
actually start. So there is no 'main', no need to actually get the bean for the
program. The progam is a POJO and its dependancies are resolved by the
container !
We simply launch the bootstrap instead of the program.
Now this all seems so clear, i almost feel stupid... : /
I hope that this post will help other, stuck in the same misconception... (
otherwise this post will simply be another public humiliation).
Thanks again Adrian !

[JBoss-user] [Microcontainer] - Re: How to access beans created by the bootstrap
First of all, thanks you Adrian for all your response. Sorry I didn't reply sooner. About doing a Spring facade, i believe that will be a great idea but I don"t know if I got what it's take to do it. I'm still pretty new to all this and the person(s) doing this job should be very good with both IoC Framework. However, I'll consider the challenge... anonymous wrote : I strongly discourage this usage. It defeats the whole point of IOC. I agree completly with you. The method "getBean' is, the way I see it, just a way to make test while trying the Spring framework... However, while doing my research an Spring and Hivemind, i found a lot of critics against the use of JNDI locator, which tends to tie the webApp to the locator, making portability and unit test not simple [ that is what i read,not an opinion ]. So let's say for the purpose of the exercice that we agree that Locator is not an option, how can we get back the Bean from the Microcontainer ?

[JBoss-user] [Microcontainer] - How to access beans created by the bootstrap
Hi,
I come from the Spring world ( please don't throw tomatoes to my face : ) ! ).
I read the microcontainer getting started. I can see that most features of the
spring core are reproduced here and i read the xml configurations quite easily.
However i have hard time understand just one thing.
Once I call the StandaloneBootstrap().bootstrap(), wich basicly parses the
XML file and creates the proper beans, how can I get a reference to those beans.
In the Spring framework, i add a static method such as :
ApplicationContext cxt = new
FileSystemXmlApplicationContext("config.xml");
cxt.getBean("myBean");
But i didn"t see anything like this in the 'A Guide For POJO developpers' ,
neitheir in the example... How can get back my instanciated bean ?
I hope that my question isn't too silly...
