Does anybody know a good way to, inside a java class, check the java version? I was thinking about passing in a path to a java class that contained the java executable IE. java checkversion.class c:\program files\java\.... I'd then take this path, change to this directory and then run java -fullversion and parse the results. Does anybody have a better idea of how to go about doing this? It needs to be available for Linux, Sun etc. Thanks

This class will be run by another process that will determine which jar it will need to use. I have a jar for 1.5+ and one for 1.4
