Using the correct JDK or changing default in Netbeans on Linux OS

Question

Disclaimer: I am new to Java, new to Linux, and new to Netbeans - apologies for any over/under explanation - please ask and I will add/remove info.

I have a model written in Java in Netbeans 8.2 that has been successfully running in NetBeans 8.2 on Mac OS. This version of NetBeans was downloaded with JDK8u171 (JDK/Java package).

All components of the model have successfully transferred through FTP (filezilla) to a remote Linux machine.

The Linux machine has a copy of Netbeans 8.2 and has java/1.8.0-oracle (and 1.6.0 and 1.7.0), and has java/1.8.0-openjdk (similarly, 1.6.0 and 1.7.0 also).

I am assuming that 1.8.0-oracle is the equivalent of JDK8u171 but I may well be wrong.

When I load netbeans using

module load java/1.8.0-oracle
module load netbeans
netbeans

The program opens (via remote desktop - x2goclient), and I can search for the project and open it.

Once open, I see:

'myprojectitle (broken)' in the project window on the left of the NetBeans GUI

right click -> resolve problems

...opens a screen saying

'The JDK is missing and is required to run some NetBeans modules Please use the --jdkhome command line option to specify a JDK installation or see http://wiki.netbeans.org/FaqRunningOnJre for more information.'

Does this mean I am using the wrong jdk/java package?

Or is the jdk package configured incorrectly in Netbeans, if so how can I reconfigure?

Any help would be greatly appreciated.

The solution to this was found at The JDK is missing and is required to run some NetBeans modules

Whereby, java/1.8.0_171 needed to be installed and then netbeans needed to be opened as follows:

netbeans --jdkhome /path/java/1.8.0_171

Apologies for a repeat, but hopefully this answer can either redirect or offer a solution
