Safari not allowed to open java jar files

Question

Safari not allowed to open java jar files

Hey everyone, each time I attempt to open a .jar file, I get a message say "nameoffile.jar Cannot be opened because Safari is not allowed to open Java JAR files. How do I fix this? I have the latest versions of high sierra and Java. It says the same thing if I try to open it by using Google Chrome also. I am asking on the apple site because it only started doing this when I upgraded to high sierra. However, my other os was out of date so I'd like to keep this one if possible.

Thank you

MacBook Pro, iOS 10.3.3

Browser's are restricted from opening jar files. That was the flaw that allowed exploits in Java a while back.

Install a Java Developer Kit (JDK) and open them with that.

Or, use the command line to open the jar referencing the JRE in the Internet Plug-In.

I don't have it installed, so I can't give you the full path. You would have to look into the Java Internet Plug-in to find the java executable, then use the full path to it followed by a space, then -jar, then space, then the path to the jar file.

Something like:

/Library/Internet\ Plug-Ins/jre_1.9.0/resources/java -jar ~/Downloads/jarFileName.jar

And I haven't been able to find anyone with the same problem or anything on java's site about it.

Would you mind telling me what to type in the command line? I know next to nothing about this stuff and haven't seen much to help me on the internet. The jar file is called imagine.jar
