The way I do it is to place version information in the Jar according to 
package standard and then extract it via java.lang.Package object or 
alternatively (and much more simpler) is to define some constants somewhere. 
I usually do something like

interface Constants
{
  String VERSION = "@@VERSION@@";
  String DATE = "@@DATE@@";
}

and then replace the constants during build process. See Ants build process 
for examples of that.

Ironically I just a second ago provided an example of this very thing on a
related topic.     Look back at the message with the subject "wildcards in
replace task".

Our build process involves using the <propertyfile> task to build a property
file at run-time with all of the build details, and the build version gets
set as the CVS tag used to build the deployment WAR file.   The versioning
scheme may need some refactoring, but in general we'll at least know the tag
used so that a build can be replicated precisely.
