This is basically what global_vars in the perl version of HTML::Template 
does.  As of now, it's not possible in the java version, and my initial 
intent was not to support it, but it seems like there are people who 
would want it in, so the next version would most likely have global_vars 
support.

For now, you'll have to use a workaround, and add sessionID to each of 
your loop elements.  Something like this:

Vector v = Newsmanager.getNews();
for(Enumeration e = v.elements(); e.hasMoreElements();) {
	Hashtable h = e.nextElement();
	h.put("sessionID", sessionID);
}

I'll add support for it in the next version, and you're welcome to see 
if you can too.
