Calling all Mac OSX Users?

Question

I'm looking for feedback on a small Java program that I've written...It's just a "fantasy game dice roller", but I would like to make sure that it is capable of running on Apple systems. I've got it working just fine on Windows and Linux, but the one person I have testing for me on Mac has had no luck...I just wanted to narrow it down to an issue with her computer or my programming... You can download the app: http://www.thoughtsandrambles.com/downloads/DiceRoller_Extreme.zip

It's nothing fancy, or even useful, but if you could just let me know if the darned thing *runs* on your Mac, I'd appreciate it. It requires that you have the lastest Java Runtime installed.

Answer 1

it's you.



the zip has a jar and the source.. the jar doesn't open!

Answer 2

everything I have is the latest Java, iTunes, system updates etc.



Can you give me a brief run down on what you are using to launch it or how you are supposed to execute it so that it runs ?



Do I go into terminal or what exactly ?



Found a tutorial on google and this is what I have done in the terminal :



shanes-powerbook-g4-12:~ shane$ mkdir dice

shanes-powerbook-g4-12:~ shane$ cd dice

shanes-powerbook-g4-12:~/dice shane$ java -jar DiceRoller_Extreme.jar

I created the directory and since I only had the Jar file I could not do the rest so I executed the jar file using that command in the tutorial.

I did tech help for iPhones for fairly much 2 years, and there are a pair of issues that spring to strategies whilst people communicate approximately evaluating those issues First, I ought to declare that i've got in no way messed with Linux, yet can communicate living house windows vs. OSX with some readability. the 1st component i will say is that the two do ninety 5% of the comparable stuff, yet they carry out a little of it in a critically diverse way. this is greater approximately taking a various direction to the comparable trip spot particularly than some commonly happening distinction in what they'd do. the version between living house windows and Mac is approximately understand-how the approach of their respective creators, discovering how their pass charts are diverse particularly than having diverse expectancies of what the two laptop must be waiting to do. there may well be something that one does that the different in basic terms won't or does not ever seem waiting to do as nicely, yet maximum folk of the certainly projects will nonetheless accomplish what you like executed (writing a rfile, updating the gadget's utility, surfing the internet, etc.) it fairly is why maximum folk of people who inform you one is palms down some distance stronger to the different, are commonly crammed with crap. till your conversing approximately one in all those narrowly defined areas, the two gets executed fairly much something you like, this is in basic terms the way it is going approximately doing it. actual, Apple seems to be fairly much proof against virus assaults and those subjects, yet you will pay probable one million/2 of what you will for an identical living house windows gadget then you definately will a mac, and with a non-mac gadget you are able to customize your gadget on your needs and desires way greater desirable than you are able to with a mac the two could be great on your desires, and the two have downfalls in diverse areas, yet for ninety+% of people they'd do high-quality with the two, and this is in basic terms a rely of non-public selection and/or familiarity.
