Java not working

I'm trying to look at the trajectory of NEO's (Near Earth Objects) at JPL website. To do so, requires Java. I have the latest version installed and it is enabled to run content in the browser (I checked with the Java control panel). I even added JPL web address to the exception list to no avail. I've tried five different web browsers and they all spit back the error. Adding the JPL web address to the exception list was the only workaround that they provided. This is so frustrating!

 

Java updates?

I got a notification on my system at boot up this morning wanting me to install a java update.

IIRC, in Win 7 it was suggested that java should not be run at all.

Is java on Win 10 safe and should I allow updates to Java?

 

Java .jar file is not downloaded as a java file.

"Reinstall or update Java Runtime Environment

If you can’t run jar files on your Windows 10 PC, you might need to reinstall Java Runtime Environment. To do that, follow these steps:

Press Windows Key + I to open the Settings app.

When the Settings app opens, go to the System section. Now, choose Apps & features from the left pane.

Locate Java from the list and choose the Uninstall option.

After doing that, navigate to Java’s website and download the latest version of the software. Once installed, check if the problem is resolved. Keep in mind that it’s not mandatory that you remove your previous Java installation, so you can skip that step and
just install the latest version on top.

Java will also automatically check for updates, and if updates are available you’ll get a notification. To update Java, simply click the notification and choose the Update option. Now follow the instructions to complete the update"
