You can sort of hack your way through this by passing data via a fake querystring. If the name of the page holding your frameset is "index.jsp", and you want a link to open your page on coffeeshops in the bottom frame, your link would look like
<a href="index.jsp?coffeeshops.jsp">click</a>
Then index.jsp would contain a script called onload that read the page's location, got the lastIndexOf "?", grabbed the substring from that index to the length of the location
string, and set that String to be the src of the bottom frame. That way your users can bookmark the page.
However, you could do it easier using the capabilities of JSP, so your link would be
<a href="index.jsp?page=coffeeshops.jsp">click</a>
and you'd just have to get the parameter "page" and write it to the page in the src of the bottom frame.
