Re: HttpSessionListener methods not called

Hi CodeSurfer, I know your question is a little ages, anyway I'm facing exactly the same problem. Were you able to solve it? How?

Thanks.

Hi mP,

I disagree with your statement that I am doing too much for the
embedded Tomcat. My server code is very simple: all I am having
problems with is instantiating the database object at the right point
in time. What is so difficult about that? Since I am - in my opinion -
not doing too much, the simple question remains why the
HttpSessionListener methods are never called. If this is a result of
hosted mode than I am forced to use an external server but maybe it is
a bug in which case it would be nice it it is solved so I can continue
to debug both client and server mode (for me as a GWT beginner that
would be a great boon). If it is something I am doing wrong, it would
be nice to know how to correct it, for the same reasons.
