I'm trying to install NetBeans on Linux Mint, and I'm getting the following error every time I run the installation script:
Configuring the installer... Searching for JVM on the system... Extracting installation data... Running the installer wizard... Can`t initialize UI Running in headless mode
What should I do to get it working?
Looks like Netbeans does not work properly with Openjdk. This is what I did (in Linux Mint 12):
sudo apt-get remove openjdk*
sudo apt-get install sun-java6-jdk
Then you will be able to run the .sh installer as usual.
In case anyone has this problem in the future, Netbeans doesn't like OpenJDK 6 but -- fortunately -- it works fine with OpenJDK 7 (as expected as for Java 7 OpenJDK is the reference implementation). Just make sure you remove any Java 6 packages before installation attempts. On Ubuntu and Mint one can do:
sudo apt-get purge ^openjdk-6-*
sudo apt-get install openjdk-7-jdk
It should work afterwards.
I hit this same issue on Kubuntu 12.04 LTS but needed Sun JDK 6 for a project I'm maintaining. I stumbled upon Martin Wimpress' OAB-Java script (by way of help.ubuntu.com) which creates and installs a local apt repository for Sun JDK 6. You can find the latest instructions on Martin's github site which run as follows:
cd ~/
wget https://github.com/flexiondotorg/oab-java6/raw/0.2.7/oab-java.sh \
-O oab-java.sh
chmod +x oab-java.sh
sudo ./oab-java.sh
If you want to see what this script is doing while it is running then execute the following from another shell:
tail -f ./oab-java.sh.log
Alternatively, you can clone the OAB-Java repo and kick of the script from within it:
git clone git://github.com/flexiondotorg/oab-java6.git
cd oab-java6
sudo ./oab-java.sh
Either way, once that is in place follow Jose's instructions to remove openjdk and install sun jdk:
sudo apt-get remove openjdk*
sudo apt-get install sun-java6-jdk
One final note, the script accepts a -7 argument which will create and install a local apt repository for Oracle JDK 7 should you want to go that route.
I was able to get it to work by getting into the target system using ssh -X, then making sure DISPLAY was exported. That handles the X server issues.
Change the priority of the Oracle Java executables:
export PATH=/usr/java/latest/bin:$PATH
Run the installer:
./netbeans-8.1-linux.sh
What worked for me was installing default java environment from the terminal:
sudo apt-get install default-jre
