I come to think that Mnesia is more integral than it looks at first glance. Even though it 'feels' like too big for being the standard way of state handling, without its transactions something is missing. Ets are not sufficient. The abolition of locks and synchs may simply requiring for transactions in common state handling or it's merely a truncation of applicability where shared state is part of the requirements? “I’ve used processes to encapsulate state (active queries, specifically) where I didn’t really need to.

I am working on something in the same domain, only instead of external auth I am working on a custom auth module and am working on developing a custom IQ handler for ejabberd for my client. Seems like a some weird problems with my IQ handler not being called although I have taken care to register my iq handler via 'process_local_iq' in the start/2 method of my module. also, my module does get loaded by ejabberd. quite weird and lack of documentation for ejabberd is a big problem as well. Seems like not a lot of knowledge about IQ handlers exists out their. SG Richard,
Interesting article. I am working on something in the same domain, only instead of external auth I am working on a custom auth module and am working on developing a custom IQ handler for ejabberd for my client.
Seems like a some weird problems with my IQ handler not being called although I have taken care to register my iq handler via ‘process_local_iq’ in the start/2 method of my module. also, my module does get loaded by ejabberd. quite weird and lack of documentation for ejabberd is a big problem as well.
Seems like not a lot of knowledge about IQ handlers exists out their.

I'm pretty sure the switch made it to the most recent release tarball, but if not you should pull from apache SVN -Todd Hey RJ,
