Just a few notes to this memo:
1. Someone on this list used openJMS (www.openjms.org) with Orion, and has good
success, after they positioned some Jar files, etc.
2. As far as teaching students, I have learned on Orion and Jboss/Tomcat. Orion is
free to developers and non commercial use, and Jboss/Tomcat is free (www.jboss.org).
3. Resin is good, if all you want is a JSP/servlet engine. If you want an EJB
engine, then Resin will tell you how to hook up with popular EJB engines (both
commercial and open source).
4. Large companies have the perception that the more you pay, the better the
product. You do get some nice features with paying the big money: Nice front end
tools, good documentation, and paid support. But from what people report in the lists
(Orion, Jboss, Jonas), the support is not necessary superior to knowledgeable people
answers questions via the list.
5. Apache and Tomcat are slated to use OpenEJB in the future (www.openejb.org).

While the EJB implementation is quite nice the JMS implementation is
lacking to say the least. Look in the archive for messages from me in this
regard.

The C code is the connector for Apache, etc. Resin's a Java product and
the Java source is part of the distribution.

JNDI should be fine as well. JMS, well...

This has lessened greatly with v6.0 but of course it's in BETA and only
for Win32 and Solaris.

WebSphere's a glorified servlet engine. For really exercising J2EE I'd
stay away.

I don't really remember but the startup time for Orion is so small it's
not that big a deal (at least for instruction). Startup time's nothing like
WebLogic that's for sure.
