Is there any way for me to execute a .jar file with JRE through the command line. I'm having an issue with the file and I wanna see if I can get any information as to what the error is. When I try to execute it with ./ it says that that it can't execute binary file. But the icon gives me the option to run with Java Runtime Environment.

You have to run it though the JRE, not directly. ie. java -jar myapp.jar
./ Is not actually a command to run a program/script/binary. It simply refers to the current directory. For example, if I have a script, myscript.sh, in my home directory;
I can either run ./myscript.sh or /home/myusername/myscript.sh
Both of those would run the script.
The reason why you couldn't just run myscript.sh is because the termnal would try to interprit it as a known command, and throw this error: myscript.sh: command not found because it isn't smart enough to know that you were trying to direct it to a file in your current dir.

As far as i know, the dote . can only be used to run shell scripts.
So you have to use java command to run .jar files
java -jar your_file_name.jar
That's it !

THANK YOU! It also inadvertently fixed the error as the script re downloaded a cache that was causing the issue! – Kody Wilson Apr 20 '16 at 18:17
