class version problem

Hi

I had re-compiled the sources of Daisy Diff open source with JDK1.5 using ant which creates a jar of the compiled classes.

However, when I checked the version of the class, it is 50 and it said I should use JDK6 or above.

Our project is supposed to work with JDK 5.

Can someone let me know how to overcome above problem

Thanks

Find the documentation for the java tool, and it has options for source and output compatibility.
 
It is sorta covered in the JavaRanch Style Guide.
