Urgent : autoinstallion of JRE

I am developing a java applet based game portal but the problem is that the applet will not run till the JRE is installed on the client machine.

I don't want the user to manually download and then install JRE.

Is there any mechanism through which i can detect that whether the required version of JRE is installed on the client machine and if not then it can automatically download and install JRE showing the same game webpage after installation ?

Please help me as this is the only thing which is delaying the project.

Regards.
