Netbeans install error: The specified jdk folder does not contain jdk

Solution 1:

Got the solution. As openjdk documentation says I installed openjdk using

sudo apt-get install openjdk-7-jre

But it's not complete installation. After that I used this command

sudo apt-get install openjdk-7-jdk

It installs several extra packages. After that netbeans find jdk automatically and normal installation completed smoothly...

You need to set the JAVA_HOME path.

Open /etc/profile with you favorite text editor, ie

gksudo gedit /etc/profile

Navigate to the end of the file and add these contents

JAVA_HOME=/usr/lib/jvm/java-7-openjdk-i386
PATH=$PATH:$HOME/bin:$JAVA_HOME/bin
export JAVA_HOME
export JAVA_BIN
export PATH

Reload your system wide PATH /etc/profile with

. /etc/profile

As an option, you can run the installer with the --javahome option pointing to the /usr/lib/jvm/java-7-openjdk-i386 path as such

netbeans-installer.sh --javahome /usr/lib/jvm/java-7-openjdk-i386

this will force the installer to use that path for the Java version you desire.
