Running Netbeans for Java

Question

I have a problem with running Netbeans for Java development..

When I try to run it I get

I checked the config located in <netbeans_dir>/etc/netbeans.conf and found following setting:

netbeans_jdkhome="/usr/"

So, I checked java and javac:

>>java -version
openjdk version "1.8.0_151"
OpenJDK Runtime Environment (build 1.8.0_151-8u151-b12-0ubuntu0.16.04.2-b12)
OpenJDK 64-Bit Server VM (build 25.151-b12, mixed mode)
>>whereis java
java: /usr/bin/java /usr/share/java /usr/share/man/man1/java.1.gz
>>javac -version
javac 1.8.0_151
>>whereis javac
javac: /usr/bin/javac /usr/share/man/man1/javac.1.gz

So I updated netbeans_jdkhome to /usr/bin/javac. Now, when I try to run Netbeans I get

Cannot find java. Please use the --jdkhome switch.

I also tried to reinstall Java according to this instruction but once I did and changed jdkhome to /usr/lib/jvm/java-8-openjdk I still get Cannot find java.

What should I enter to run Netbeans properly?

In NetBeans select Tools -> Java Platforms -> Add platform, and browse to the desired JDK folder. — zlakad, Mar 11 '18 at 15:30
Well, what is displayed when you select Tools -> Java Platforms (in the **NetBeans** IDE? — zlakad, Mar 11 '18 at 15:32
Normally your java installation is in `/usr/bin/jvm/` or something like that. — Olivier Grégoire, Mar 11 '18 at 15:35
It's looking for the base installation directory of the JDK. You pointed it at the singular `javac` binary — OneCricketeer, Mar 11 '18 at 15:36
@zlakad In the specified window it shows me only JRE... @cricket_007 I tried also `/usr/lib/jvm/java-8-openjdk` but it didn't help either... what value should I enter then? — Tomasz Kapłoński, Mar 11 '18 at 15:39
Can you please show `echo $JAVA_HOME`? And can you also show the contents of that directory if that variable is not empty? — OneCricketeer, Mar 11 '18 at 15:44
Well, that's the first problem. Netbeans actually looks for that variable. https://askubuntu.com/questions/175514/how-to-set-java-home-for-java — OneCricketeer, Mar 12 '18 at 06:16

Tools -> Java Platforms -> Add platform should display something like this:

Notice that Platform folder has small rectangle that indicates it can be chosen.

**export PATH=$PATH:/usr/lib/jvm/java-8-openjdk/bin** *(Note: "/usr/lib/jvm/java-8-openjdk" is symbolically used here just for demostration. You should use your path as per your installation.)* In your comment you used `/usr/lib/jvm/java-8-openjdk`... If this is the path where you installed your java, just add `/usr/lib/jvm/java-8-openjdk/bin` – zlakad Mar 11 '18 at 15:57

Ideally, you `export JAVA_HOME`, and then `export PATH=$JAVA_HOME/bin:$PATH` – OneCricketeer Mar 12 '18 at 06:16
