JAVA on Mojave

I have been unable to resolve this from looking at other posts. Let's assume I was a proficient Windows user, and have recently made the switch to MAC, and have no clue how to navigate and do all kinds of convoluted things that were second nature to me in XP ..... so ...

I've got a network thermostat system that requires a jar file be run so I can access it. All the reading I've done so far seem to require almost programmer-like skills to make a JAR file work on a MAC ....

Is there not a SIMPLE way to allow one (or possibly two) JAR files to operate without having to get behind the guts of the Mojave OS to do so?

Thanks! And please use language that a very tired windows power user can understand... I no longer want to work for my computer.... MAC was billed as working for ME. :).

thanks!

Running jar files from inside a browser is a security risk and most modern browsers disallow it.

You can download the jar file to your mac and run it just by double-clicking.

If you don't have java installed, you will have to install it.

If you need help with that, just search for "java mac" on the web.

I would have thought that what you need is a jre (java runtime environment) and not need a full blown sdk, but that would do too.

Googling “java mac” takes you quickly to Oracle’s java site where you can download what you need (Oracle is the owner of Java since it acquired Sun some years ago).

FWIW, if you install the JDK you get JRE with it and my experience says some

.jar will work with one or the other or both. It all depends on the classes

required by the .jar application.

So, to be safe, just install the JDK and be done with it.

There is no issue running jar files. Normally all it takes is to execute them. Maybe the issie is you are familiar with XP, an antiquated OS that no one has supported for a decade or longer.

What exactly is the issue when you try to run the jar file? Maybe the thermostat system is designed for old Windows systems only.

Thanks for the reply Bob. There is an issue running jar files.... Safari says it just plain won't. Neither will Firefox. From my readings, Apple nixed jar files in their Safari browser due to some security issue and I'm just looking for a workaround.

Yes to both of your statements.... I disclosed this up front :) I am familiar with XP, AND the thermostat is was designed for that but will execute on a MAC as long as said mac can execute a jar file. So now that I've moved to MAC, it will need to support a few thousand $$ of these thermostats that I have in several buildings. I'm hoping I don't have to keep an XP machine running just for this sole purpose.

I am in the process of learning the MAC but was hoping for a non technical solution, since it's going to take me a bit of time to become as proficient in Apple as I was in XP.

Here is what the MAC says to me when I double click on the file in question"

To use the “java -jar NetX Device Discover.jar” command-line tool you need to install a JDK.

It tells me this is a Java developer's kit... is that really what I need to run this file?

Thank you
