Nancy-- The only way to pass data from Javascript (to my knowledge) is through a URL or post etc. Maybe variations exist such as using hidden fields on forms etc -- however, these all revolve around opening a HTML/JSP page with query / post data.
If your data already exists in the Java world, then you can simply access the session data as pointed out by Paul in his previous post.

In the first case the session is the safest way (because the data is managed on the server, no client can directly "touch" it). 2. Use SSL. It's unsafe even if you make your own socket connections. "They" :) still might get it. Anyway, using the session you can choose to delete the data at any time (simply invalidating the session). The session's purpose is the use in pages like you described.
