If you're working with a Servlet 2.3 implementation, and your container
automatically creates sessions for each user, then you could simply
implement and register a javax.servlet.http.HttpSessionListener. From there
your container would auto-magically notify your listener when new sessions
are created.
In reality, you're probably working with a Servlet 2.2 implementation, so
you're options are a bit more limited. One technique I would consider is
implementing a common ancestor for all of your actions which provides a
method like this:
protected void initSessionIfNecessary() {
// check for the presence of a session attribute
// if its not there, load session attributes
// you'd like to prepopulate using the
// user's credentials
}
The main penalty of this approach is ensuring all your actions call this in
their perform method. Personally, its one I can accept, because I know the
2.3 spec. will be here soon enough.
