There's a task for running a command (in the command line interpreter
of the local system); it's <exec> or something like that.  It takes 
elements for specifying environment variables for the invocation of the 
command ("<env>" maybe?).  

Use such a task to run Ant (that is, something like "ant sometarget")
would be the command to execute.  Use environment-variable subelements
to set "JAVA_HOME" to the appropriate value for target "sometarger".
