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

During installation of Netbeans 7.3 I got this message

the specified jdk folder does not contain jdk

I have openjdk 7 installed on my system using apt-get. I tried to specify the path to /usr/lib/jvm/java-7-openjdk-i386 and also tried to /usr/lib/jvm/java-7-openjdk-i386/bin but nothing works. What should I do?

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.

for me it works. I installed Netbeans 8 and it ask me to join the jd path.

I used the first answer:

sudo apt-get install openjdk-7-jdk

than

sh netbeans-8.0-linux.sh (suppose I'm in the /home/MYNAME/Download/ where I downloaded .sh file)
