Were you the one who asked this question on the users forum?  Anyway, 
I'll answer it here too.  Yes, you can.

You'd have to have something like this:

Hashtable(
	loop1  =>  Vector1 (
				Hash1(loop2  =>  Vector2)
				Hash2(loop2  =>  Vector3)
				Hash3(loop2  =>  Vector4)
			   )
	 )

Of course, Hashtable, Hash[1-3] would also have other elements.  The 
first hashtable is optional, since it is created inside the template 
anyway.

So, java would be like this:

Template t = new Template(...);

Vector v = new Vector();
for(outer_loop) {
	Hashtable h = new Hashtable();
	h.put("field1", value1);
	...

	Vector v2 = new Vector();
	for(inner_loop) {
		Hashtable h2 = new Hashtable();
		//populate h2
		v2.addElement(h2);
	}
	h.put("loop2", v2);
}

t.setParam("loop1", v);

And set any other params as you want them.
