Is there a App in the repository or yum install that will do this?
I have a few Java jar files i would like to open.

The files do not seem to open with Java.Or maybe i need an updated Java version?

Thanks.

same as windoze

open a terminal
navigate to the directory where the jar file is

use the command

java -jar filename.jar

if that is not working, then a straight
java
or
java -version

in a terminal will give info

Rod, you have two options to run Java in Fedora. You can install OpenJDK (& icedtea) which is probably fine for most uses or you can install Oracle Java.

I tend to avoid Java because of the high security risk with the package. Their track record on keeping security holes plugged isn't exactly what I'd consider stellar.

Thanks guys.

A bit more

Assuming you have java installed, cant see why not

In win you might have a <something>.exe launcher

the linux equivalent might be a bash script <something>.sh

the contents might look along the lines of (example for imagej

#!bin/bash
java -Xmx512m -jar /home/user_name/ImageJ/ij.jar

and this will allocate extra memory etc.

a couple of ways you can run a bash file
sh filename.sh
or if you make it executable use 'dot-slash'
./filename.sh

Thanks Rich.
