First make sure you really have JDK installed on your system, by typing the following in a terminal:
If you already have it, what should be expected since you installed Netbeans, then probably you haven't set it in the Java Platform Manager in Netbeans. In order to do it just open Netbeans and navigate to Tools -> Java Platforms -> Add Platform... button and specify the path to your JDK folder.Code:dpkg --list | grep -i jdk

Now that you have a confirmation for JDK, you just have to point the Java Platform in Netbeans to your openJDK location like I posted previously.
If you don't know its location (/usr/lib/jvm/ usually) just type at a terminal window:
Code:whereis java

java: /usr/bin/java /usr/bin/X11/java /usr/share/java /usr/share/man/man1/java.1.gz
Also do I have to uninstall openJDK?
By the looks of it your JDK location is at /usr/lib/jvm/ that's the location you have to add to Java Platforms in your Netbeans.
No, if you uninstall it you won't be able to develop in Java since it's the JDK that contains the collection of the Java programming tools.

How to set it in netbeans I'm not getting any option to set it in NB 7.2.1
Open Netbeans and navigate to Tools -> Java Platforms, click the Add Platform... button and specify the path to your JDK folder.
Another way is to edit the netbeans.conf file and change 'netbeans_jdkhome=' value according to your JDK location. Something like this:
Code:netbeans_jdkhome="path/to/your/JDK/location"

There is no option for Java Platforms in tools, there is just Tools --> Options/ Plugins .
And how to edit the file?
