Windows 10: can I run a jar file using a JRE downloaded with minecraft?

Hi I have a strange question. So minecraft no longer requires that you install java to play it. How this works is it downloads a a JRE to you computer that it uses to run the game. Anyways, there is a map viewer tool that can be used to locate things in your world and it it written in java. So I was wondering if it would be possible to run it with the JRE downloaded with minecraft so I don't have to install java. You can download the tool as a jar file. Also in order to run a server you need to download the minecraft server.jar. So, can I run a jar file using the JRE downloaded with minecraft?

JRE and .jar confusion

Hello,

I was trying to open a .jar file but I only got a lading circle. I then went to Execute.jar file won't work and now I can't open the file or work
at all with java files. I reset the default program for .jar files. Is this enough to undo any damage I may have caused by following the article, or do I need to reset the location of teh jre as well? How would I do that for windows? Btw, I know how to set
it in netbeans and eclipse and can still run .java files (but not jar files) in these programs.

I hope this makes sense, but if it doesn't let me know and I'll try to re-explain this.

Thanks

Can't open .Jar file using Windows 10

 

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

Have you tried the second solution?

"Open the Settings app. Navigate to the System > Default apps.

Scroll all the way down and select Choose default apps by file type.

Locate the .jar file type and choose a default application.

This method offers limited options and you can only choose applications recognized by Windows 10. Fortunately, there’s another method that you can try. To change file associations, do the following:

Press Windows Key + X to open Win + X menu and choose Control Panel from the list.

When Control Panel opens, select Default Programs.

Click on Associate a file type or protocol with a program.

Locate the .jar file on the list and double-click it.

A list of suggested applications will appear. Click on More apps.

Scroll all the way down and choose Look for another app on this PC.

Locate the javaw.exe file. By default, the application should be located in Program Files folder. Select the application and choose it as a default for .jar files.

Optional: Some users recommend changing the parameters of javaw.exe. To do that, simply locate the file and create its shortcut. Right-click it and navigate to the Properties. Now, locate the Target file and add -jar “%1” % . Be sure to select this newly created
shortcut in Step 7.

You can also change file association by right clicking the jar file and choosing Open With > Choose another app. After doing that, follow the steps 5 to 8 from the above"
