Java application is not able to find JDK 1.7 on Mac (Installer created with install4j)

Question

I have created a Java application installer using install4j for Mac OS X. My application uses JDK 1.7.

I have set the JDK version in install4j properly as well.

I have also installed JDK 1.7 on Mac and when I type java -version command on console it gives me JDK 1.7.

Application also installed successfully but I am out of luck, when I try to start the application it gives me this error:

Exception in thread “main” java.lang.UnsupportedClassVersionError: a (Unsupporte d major.minor version 51.0)

The above error occurs because it uses Apple's inbuilt JDK 1.6. I want app to use JDK 1.7 which is already installed on the machine.

Edit

Now I have created installer by selecting OpenJdk in jre option. Now it is not giving me the UnsupportedClassVersionError but now application icon blinks on the dockbar and goes.

Below is the cosole log.

In the media file wizard for your Mac OS X installer, go to the "JRE" step and select "Installed OpenJDK JRE (Java 7 and higher)".

If you do this, it's not possible that the installer and the launchers use the Apple 1.6 JDK, so this must be a different problem. – Ingo Kegel May 13 '13 at 09:41
I have not installed Open JDK 1.7 I have installed Oracle JDK 1.7. – Mohit Charadva May 13 '13 at 14:07

Yes, that is effectively OpenJDK (as compared to Apple JDK). – Ingo Kegel May 13 '13 at 15:10
So, what should I do to run it on Oracle JDK 1.7 because I don't want to use Open JDK 1.7. – Mohit Charadva May 14 '13 at 06:41

When you say "OpenJDK" on Mac OS X what is effectively meant is Oracle JDK. Oracle JDK is basically the same as OpenJDK. And my answer says what you have to do to run it with Oracle JDK. – Ingo Kegel May 14 '13 at 07:19
