I want to display a message to the user informing them that the minimum version of Java that must be installed is the value I have set for the <minversion> element of my Java validVersion. I believe that you provide this functionality, but I just cannot figure it out from your documentation

You can specify one or more valid versions by specifying <validVersionList> for <autodetectJava>, which whould include one or more <validVersion> definitions - each defines a valid version that can be used.

For example:

<autodetectJava> <promptUser>0</promptUser> <validVersionList> <validVersion> <maxVersion>1.7</maxVersion> <minVersion>1.4</minVersion> </validVersion> </validVersionList> </autodetectJava>

This will accept any version of Java between 1.4 and 1.7, inclusive.

I understand how to setup the "validVersionList" and already am doing do. My question is not about how to specify a minimum java version, but how do a get that value ("1.4" in your example) as a variable so I can insert it into a message that I display to the user. Something like....

"No valid version of Java could be located on your system. Our application requires a minimum Java version of ${minVersion}."

Thank you for the explanation. It is not possible to retrieve what you have set in the <validVersion>. What you can do is set the minVersion variable earlier using <setInstallerVariable> and then specify <minVersion>${minVersion}</minVersion>.

That is what I figured out.
