Newbie - basic questions about Javabeans

Hello,
I decided to write a simple application using Javabeans  in NetBeans
IDE 6.0.
I created a frame with few buttons and fields.
I gave a name to all fields and buttons. I switched from Design to
Source and I see code like this:

jButton1 = new javax.swing.JButton();
....
jButton1.setName("b_exit");

The above code cannot be changed.

My questions:
How I should I access object I created - I don't want to use name like
jButton1 - I want to use name I assigned like b_exit.
Is there any example of building simple application using JavaBeans?
Which book do you recommend for learning Javabeans?

Thanks,

Zalek

You pretty much have to use jButton1.  You can change that name too.
Right click on the component and select "Change variable name".

This is Swing, not Javabeans.  Try to learn Swing.  I recommend
_Learning Java_ by O'Reilly, it's a good introduction to Java, including
Swing.  Once you get a handle on that, Sun's Tutorial becomes easier to
read and understand.

Mark,

My question was related to Javabeans IDE. In this IDE you build GUI
similar way as in VB or Powerbuilder - you do not use explicitly any
layout manager - IDE is doing this work for you. I created GUI, it is
displayed - my question was how to programaticly change contents of
this GUI.

No, you said "NetBeans".  I use NetBeans 6.0.1 and I'm familiar with
Matisse, the GUI builder.

JavaBeans is different from NetBeans.  JavaBeans is a spec.  NetBeans is
an IDE. Very different.

JavaBeans is an idea that never went anywhere.  All that is left of it
is the get/setter naming convention.

That is not fair, nor true.  JavaBeans events and property sheets are used
still.  By those who know of them.  For example, many IDEs use them that way
.

Thanks for all replies - maybe I didn't explained clearly what was my
problem.
I am using IDE NetBeans to create a JFrame and Java program to use
this JFrame. The problem was that IDE Netbeams created names like
JButton1, JButton2 etc, while I wanted to use "human" names like
t_name or t_user. Using properties of the objects name was not
changed, only command .setName was used.
I found that mouse right click on an object changes object name - this
is what I wanted.
Thanks,

Zalek
