Load Provider

Hi everybody.

I’m developing a plugin using smack library (using Eclipse platform) to use it under Spark Client.

The plugin installs a Provider (.class) which is listenning some extension messages.

But this plugin is loaded by spark when some messages have already arrived and I can’t process them.

How can I configure the Spark in order to load the provider before the program is started?.

I have read in the Internet that there is a file called smack.providers but I can’t find it.

Could you help me?.

Thanks you.
