I had the same problem with ldap.jar & providerutil.jar (providers for JNDI). The problem is that due to the way Orion does its classloading mail.jar classes are loaded by an Orion classloader (via the manifest in the orion.jar) at a *lower* level than the classloader that handles orion/lib. The ways you can fix this (which are both kind of hacks IMO) are to put pop3.jar in your jre/lib/ext directory, or run orion as "java -classpath orion.jar:pop3.jar;etc com.evermind.server.ApplicationServer" To make this a little simpler I have written a shell script to include all jars in my own "lib" dir, all orion jars, etc into a CLASSPATH var, and then run Orion as above - so, you can start/stop orion w/ "orion start", "orion stop", "orion run", etc. If there is any interest I could send this script out... I think the problem is really with Orion including some of the J2EE jars as standard in the orion.jar manifest. It's a nice idea, but based on the above problem it would be easier just NOT to include them. So, to the Orion developers out there, please: 1) don't bother to include mail.jar/jndi.jar/etc (or put them in orion/lib instead of the orion.jar manifest) or 2) fix Orion classloading to work with the provider mechanisms of JavaMail and JNDI because 3) get Sun to change the provider mechanism to use different classlaoders/etc is not very likely...
