How to convert jar file to DMG from windows Operating System

I had Developed Java Application in Windows 7.

And I had made JAR file of that application.

Now I want to convert that File into DMG format which is compatible for MAC Operating System.

Can any one Suggest me steps please?

I tried into terminal But got this errors.

I had tried to use tha JAR file to MAC OS but cant succeeded. :( — Nirav Dabhi, Mar 13 '14 at 09:00
Search for "windows create dmg" - you can put the JAR *in* an [Apply Disk Image (DMG)](http://en.wikipedia.org/wiki/Apple_Disk_Image), but if you can't run the JAR by itself, it won't run if you put it in a DMG either. — user2864740, Mar 13 '14 at 09:00
Let me guess: You tried with double-click? Try to execute it via terminal command: `java -jar yourJar.jar` — Branislav Lazic, Mar 13 '14 at 09:01
But I have exzatly no idea how to do this. I had tried to search for this already. — Nirav Dabhi, Mar 13 '14 at 09:01
Now, that's another question. At least it will work if program is correctly written. — Branislav Lazic, Mar 13 '14 at 09:14
I have whole project which contain Numbers of class files, but It successfully Run on Window OS. But it doesn't run in MAC OS. — Nirav Dabhi, Mar 13 '14 at 09:17
@NiravDabhi So fix that (learn how to correctly run the JAR on OS X), *without* worrying about a DMG. — user2864740, Mar 13 '14 at 09:26
Google `UnsupportedClassVersionError` - that normally means the class was compiled for a newer version of Java than you are attempting to run with — Nick Holt, Mar 13 '14 at 09:48
We had made the application in JDK 1.7 and the Version of MAC is JDK 1.6. Is this error cause of this? — Nirav Dabhi, Mar 13 '14 at 09:54
Yes, either upgrade your Mac or when you compile include the `-target` as described in http://docs.oracle.com/javase/7/docs/technotes/tools/windows/javac.html — Nick Holt, Mar 13 '14 at 09:58
can you tell me how to write the command prompt "-target" with example please? — Nirav Dabhi, Mar 13 '14 at 10:23

The below link explains the steps. I've also copied the answer which worked for me.

Copied from convert java app to mac installer...dmg

Use "Jar Bundler" in the XCode download from Apple Developer Connection.
