How to initialize (session) seam context ("No active session context" problem)?

[vlax]

Hi!
I have to integrate two web apps: one is an old one and another is based on seam. It almost works, but problem is log in feature. I need to call

identity.login()

method from the (old app) jsp file. That is impossible because of the No active session context exception (thrown by

Identity.instance()

method). Is there a way to explicitly initialize seam context i.e. to trigger session context initialization before (identity) component usage?

Thanks

I'm assuming you have access to the HttpServletRequest object - if so, you can create a session context manually and retrieve the Identity instance from it directly:

Context ctx = new SessionContext( new ServletRequestSessionMap(httpServletRequest) );
Identity identity = (Identity) ctx.get(Identity.class);

Actually, that probably won't be enough to perform full authentication.  I recommend that you wrap your Seam-specific code in a ContextualHttpRequest, that way you'll get full access to all Seam contexts (and be able to authenticate).

Thanks Shane! It works now (well, most of it :)). I hope that Seam API docs will reach the same level of quality as the Seam framework itself.
