My question is: who told you that it was impossible? The only way that Java
knows what its home directory *is* by reading the user.dir property. What you
have done is exactly right and really out to be an easier (and relatively
platform independant) way to implement the "java" task - which in this case
would NOT probably be a subclass of the exec task. Of course,
