Hi Theuns,

I'm on Feisty Fawn (7.04). I'm forwarding this to nbusers, hope you're
subscribed to it.

Not having seen the rest of the conversation, may I ask what exactly the
problem is? Another reappearance of [1]? I have been using NetBeans (6.x) on
Ubuntu versions ranging from 6.10 to (now) 8.04 so maybe I could provide
some assistance...

Cheers,
Kristian

HI
Yes I looks like the one [1].
Is this a ubuntu issue?
Is there work arounds for it?

I am not sure about this, to be honest: I remember conversations on nbusers
where people reported combo boxes to be merely unusable thanks to this. In
my case however, this never really happened, the only thing I noticed were
combo boxes broken in Swing applications using the GTK LaF (which is what
will per default happen if you use a recent JDK and the stock Ubuntu (Gnome)
desktop). In my case however...

- ... this used to be at the very best a "cosmetic" issue with no real
impact on usability of the application,

- ... this also seemed to depend upon the theme used for the Gnome UI, worse
in some, better in others.

Maybe however this also is due to the fact I never really used JDK installed
from the Ubuntu repositories but still do keep Java downloaded from
java.sun.com and installed to /opt/ like I did for the last ten years, so I
am also always running the "latest" JDK update. In your case, though, I
would first see whether switching the Gnome visual appearance / theme does
change anything about this - obviously some GTK engines don't go that well
with GTK LaF, and maybe the default Ubuntu "Human" theme is amongst them.
Afterwards, I'd possibly try to see whether or not using a JDK newer than
the one provided by your Ubuntu installation might address this issue (maybe
using the pre-release JDK 6u10 builds?). Feel free however to get back with
any questions that might arise here; maybe we can provide you with some more
hints on that...

Cheers & good luck,
Kristian

HI Kristian

I have java 6 update 6 on my machine at the moment , I am busy getting Java 6 update 7 , and the beta 10 version to see if there is any improvement.

My java is installed by the synaptic package manager under /usr/lib/jvm/
or must it be under the opt/ folder?

cheers

For what I have seen now, there are at the very least some performance
improvements in beta10 that make dealing with it surely worth it, even
you're likely to stumble across one bug or the other (after all it's in
beta... ;) ).

Actually it doesn't matter. :) For the packages installed via synaptic,
/usr/lib is perfectly fine. If you manually install a JDK using the
installer i.e. from java.sun.com, you should put it to /opt per convention
as this is the place where "third-party" software more or less generally is
supposed to be installed. The only thing then is to keep your environment
variables (most notably $PATH and $JAVA_HOME) set up right, more or less
something like this

export PATH=/opt/java/bin:$PATH

in my case to "override" the distro-installed JDK. As far as this is
concerned: I have yet to find out what's the difference between Ubuntu
shipped JDK and a "stock" java.sun.com JDK, but there are at least two
differences make me fall back to the java.sun.com one:

- In some VMWare ESX installation of Ubuntu Hardy, I installed Glassfish and
JDK off the Ubuntu archives and had rather strange exceptions being thrown,
totally failing to start glassfish. Googled around a while without really
finding a solution, eventually replaced both glassfish and JDK by bits
installed using the "non-Ubuntu" packages and never saw that issue again.

- Installing a JDK on Ubuntu is likely to make the package manager install a
whole load of dependencies caused by the visual components in the JDK, so
doing an "apt-get install sun-java6-*" all of a sudden might fill up your
server drive with a lot of xorg-* stuff which you wouldn't really need but
which is required by the java packages because you _could_ want to use it.
Installing a simple JDK knowing you'll not use any UI (ControlPanel,
JConsole, ...) on the headless server anyhow is an easier way here.

So, cutting it short: In case of any JDK problems using a
repository-installed JDK, I'd go for a java.sun.com JDK first, trying to see
whether the problems disappear then. And don't forget about playing around
with the GNOME themes, of course, in your special case. ;)

Cheers,
Kristian

Ubuntu uses the /etc/alternatives construct (aptly described as "an impenetrable forest of symlinks") to determine which version of java (and other executables) is used when working from the command line.  Install the galternatives package to get a GUI admin tool to change the default settings.  This will help ensure that you are using the same version of java if you run you app outside of NetBeans.

Based on info that I found researching this on the Internet, I believe that you need beta 10 or higher.
