Netbeans 6.9.1 on Ubuntu 10.10 Installation – OpenJDK problem
February 6, 2011 | 
Author I wanted to install Netbeans IDE 6.9.1 (C/C++ version, but I believe that the problem is generic) on my Ubuntu 10.10 laptop, so after downloading the latest version from netbeans.org, I tried to install it:
$ ls -l netbeans-6.9.1-ml-cpp-linux.sh -rw-r--r-- 1 ** ** 36699136 2011-02-06 00:58 netbeans-6.9.1-ml-cpp-linux.sh $ chmod +x netbeans-6.9.1-ml-cpp-linux.sh $ sudo ./netbeans-6.9.1-ml-cpp-linux.sh |
and got the following output:
Configuring the installer... Searching for JVM on the system... Extracting installation data... Running the installer wizard... null |
The installation wizard (GUI) did not appear at all.
Luckily, I “immediately” thought “hmm, I re-installed Ubuntu quite recently, did I install JRE?”
So, I checked if I had “Java” installed and checked that everything is “good”:.
$java -version java version "1.6.0_20" OpenJDK Runtime Environment (IcedTea6 1.9.5) (6b20-1.9.5-0ubuntu1) OpenJDK Client VM (build 19.0-b09, mixed mode, sharing) |
As you can see, I had OpenJDK installed..
For some reason, which I don’t know, I had already installed the Sun JDK, but not removed the OpenJDK, or at least set the java to point to the Sun version.
So, using synaptic, I unistalled OpenJDK (you can (un)install OpenJDK and Sun JDK from the Software Center also):
$java -version java version "1.6.0_22" Java(TM) SE Runtime Environment (build 1.6.0_22-b04) Java HotSpot(TM) Server VM (build 17.1-b03, mixed mode) |
And then, everything worked fine..

Actually you don’t HAVE to uninstall openJDK , you can configure which one to use by default with :
# update-alternatives –config java
and choose there.
This will update the symlink in /etc/alternatives. In ubuntu since I don’t remember when , /usr/bin/java points to /etc/alternatives/java which in return points to the actual binary .
I had lost couple of days some years back with something similar 🙂
Exactly. You are right.. The
in the post refers to this alternative (without providing the how-to do it :-O).
