JRE Versions

I am deploying a Java application soon, but I am running into a problem. To deploy the application I need to install the jre on the users machines for them to run the application. The problem is that I developed the application in JDK 1.4, and half of the users have jre1.1.7 installed on their machines because of some thord party software. I can not alter the version on their machines, but I need them to be able to run both the third party application and my application.

Can someone give me some ideas on how I can accomplish this?

thanks
