2 Minute Video: Groovy Makes Java Better
The first of several screencasts I am planning in relation to Groovy:
PS: When I said "on our dialog", I should have said "on our Groovy class".

Why do you have to call toString() on what is returned from the getText() call (in Java)?

I wish we could have Jython support in NetBeans IDE: If you've jython installed on your machine, try following:
<pre>
ijazfx@mypc:~$ jython
Jython 2.2.1 on java1.6.0_07
Type "copyright", "credits" or "license" for more information.
>>> from java.awt import *
>>> from javax.swing import *
>>> frame1 = JFrame('Hello World', size = (400, 200))
>>> frame1.visible = True
>>> frame1.move(300, 100)
>>> frame1.dispose()
</pre>
I think jython is shorter than Groovy to write java programs, plus is completely dynamic.

Mario,
DisplayProvider#getText() will have the return type of java.lang.Object, because the field 'text' is not typed (defined with "def" and not a solid class).

Great Demo... and great sound quality! What did you use for recording it?
cu tomorrow in Poznan!

That's so cool!
Go groovy & NetBeans!

Chris,
I still don't think you need the call to toString(). Right?

I would expect Groovy and Jython to be similar length:
import javax.swing.*
new JFrame(title:'Hello World', size:[400, 200], visible:true).with {
move(300, 100)
dispose()
}

I love the Groovy Support in Netbeans :) Makes Java fun again...

This was pretty cool.
Definitely looking forward to checking out groovy now.

Jython is cool and make things very simple but I liked Groovy with the SwingBuilder, Griffon and now this support on Netbeans is pretty neat.

While the groovy-java demo works fine in 6.5, when using 6.7 I get a "can not find symbol" error for the groovy class in the java code. Is there some additional configuration needed for 6.7 that is not needed in 6.5?

That's a known bug, I am afraid. It should still run successfully though. The first patch to 6.7 (once it comes out) should resolve this issue.
