Re: [xmlblaster] Problem with broken XMLBlaster connections

[Marcel Ruff <mr at marcelruff.info>]

Dear David,

it seems the client was away some time and the server decided
to destroy the session. And this failed to be done properly.

When later the session reconnects it enters a stale session.

The xmlBlaster you are using is about 5 years old (v1.6.2),
is it possible to upgrade to v2.1?
In this case you would also need to upgrade java to 1.5 or above (I would recommend the newest v1.7x)

I'm on holiday for a week, I hope the issue is not too urgent if you consider
to remain with v1.6.2 ...

thank you
Marcel
