I assume PROTOCOL and ACCOUNT should be "PROTOCOL" and "ACCOUNT"?
If not, what are the values?

Maybe you can try the following:
Enumeration e = mysession.getAttributeNames();
while (e.hasMoreElements()) out.println(e.nextElement());
That way you can at least see what attributes are attached to your session.

One more thing.. you also need to implement the Serializable interface for any object
you want to attach to a HttpSession. I assume this Protocol class is being written by
you, so you should make sure it implements Serializable.
The logic behind it is simple, you can only send plain text in a webpage and an object
by
default is binary.
Hope this helps.
