No Java 6 on Mac OS X Leopard
This picture says it all!
If you're thinking about upgrading to Leopard and you do Java
development on your Mac (at least try to), don't bother. I
searched for hours trying to find Java 6 on Leopard and it just isn't
there. I did install some documentation pack but I can't even
find it after I installed. Honestly, I only bought the
Leopard upgrade for Java 6. There's really nothing else that
is noticably worth it so far. My fan control stopped working.
I have about a 1 year old Macbook Pro "17 with the core duo.
So now I have a hot Mac again.
Things actually
seem more sluggish than before. I already had to restart
Finder which I NEVER had to do on Tiger. All in all, as a
Java developer, I might have to move off the Mac OS X platform.
This hardware is just too expensive to boot into some
inferior OS like Windows.

Well now is your chance to get that question answered.
I will be involved in a
Sun
Developers Network "Ask the Experts" starting October 22,
2007.
Brian
Leonard, a fellow NetBeans Evangelist, as well as

NetBeans 6.0: Making Me a KeyBoard Junkie
I was recently at a conference giving a demo for the new NetBeans 6.0
editor features. In preparing for the demo and actually doing
it, I realized that reducing keystrokes is huge for
developers. I've been so accustomed to broken IDEs
where I had to cursor and mouse around that I didn't realize how much
NetBeans 6.0 editing has improved until I was in the middle of this
demo. I actually got a rush hitting the "Enter" key and
seeing smart code completion save me lots of keystrokes. I'm
becoming a keyboard junkie (no sneering from the emacs crowd) so now
I'm looking for more keystroke saving key bindings. A great
resource to get started on Java editor enhancments in NetBeans 6.0 is
the
Java
Editor User's Guide on the NetBeans public Wiki.
Two keystroke and mouse saving features I recently found
useful are
AST (Abstract
Syntax Tree) selection and
Next/Previous Tab.
The
AST (Abstract Syntax
Tree) keymap
is listed in the "Tools->Options" (Preferences on
Mac OS X) under the "Keymap" heading. The actual setting is
"Other->Select Next Element/Select Previous Element".
This lets you select things like a keyword, a line, and a
block of code. The default key mapping is "
Alt-Shift-PERIOD" (
Ctrl-Shift-PERIOD on
Mac OS X) to select more and "
Alt-Shift-COMMA"
(
Ctrl-Shift-COMMA
on Mac OS X) to select less.
I found out about
Next/Previous Tab in
Gregg
Sporar's blog. But I couldn't get this to work so I
did some investigation. On Mac OS X the default key binding
to do a Next Tab is "
Meta-PAGE_DOWN".
To get this to work you need to press "
Meta-Fn-PAGE".
Pressing three keys at once really doesn't save me much so I
remapped this to "
Meta-DOWN"
and "Meta-UP". Note that you will have to "Remove" these key
mappings from the "Other->Insertion Point to End of Document"
and "Other->Insertion Point to Beginning of Document".
Above all, trying hitting the "Enter" key when you're doing code
completion and you'll be amazed at just how smart the code completion
really is. Happy keyboarding!
