POP3 providers

[Florin Manolache]

I want to use a pop3 provider implementation (from sun) in my application on
Orion server(1.4.0). The specs said that I should put my javamail.providers file
in /META-INF directory and the pop3.jar in /lib directory, but Orion just
ignores all these and reports that there are no providers for this protocol.
What I am missing here ? Has anyone have some examples ?

Florin.
