GlassFish session id when first time site is loading

Question

Here is the problem. I get the sessionId with:

request.getRequestedSessionId();

However when site is opening first time it returns null. Only starting with second visit it returns session id. But I need to know from first time. Can I get it?

Answer 1

It's null because there is no session.

Consider instead:

request.getSession(true).getId()

which will create a session if one does not exist, then provides a unique session identifier.
