Running a .jar file inside Innosetup Installer

Hi All,
I am developing an windows installer for a software developed in java using Innosetup.
While Installation I need to check the license key for the software.
For that I have written some code and it's been packed to a .jar file.
Now I need to execute this jar file before Installing the software.
Please tell me how to do this inside innosetup script...
Is there a way to display the status returned from the .jar file during installation and prohibit the user from installation if the license key is invalid..

Thanks In Advance...

Hi anand4nk. This forum is more sys/admin than developer oriented. You may have better luck in one of the software development help forums. I'll keep this here, just in case someone with the answer comes along.

As a developer, I know that creating the installer is a large task. I do not look forward to the day that rises to the top of my to-do list.

Good luck with that.
