Question

How can I set my java jar application to use jre 6 instead of jre 7?
I’m doing this because there are some compatibility issue with the libraries I’m using if the application use jre 7.

Edit:
The application will come with its own installers (using advanced installer) that have a jre6 installer. But I don’t know how to trace the installation folder of the jre6.
How can I trace it and make the jar file use the jre6?

Answer 1

When running your application using java.exe, you could provide the absolute path to a Java 1.6 installation. Something like:

absolute_path_to_java6_dir/bin/java -jar yourRunnableJar.jar

or

absolute_path_to_java6_dir/bin/java -cp .;yourJar.jar;otherJarFiles className
