Hi,

Can I use JMS in a Tomcat-only environment, i.e. my web applications are all
run in Tomcat, instead of a full j2ee server?

Regards,
James

Absolutely. JMS is not J2EE. You may be confusing JMS with MessageDrivenBeans.
(MDB are part of J2EE and use JMS.)

I'm not sure that I follow your distinction. EJB does not imply J2EE, or
vice versa. My understanding is that EJB, JMS and J2SE are referenced by
J2EE, but none of them require it.

Tom, EJB are part of the J2EE api. AFAIK they can only be run in a J2EE
container.

Historically impossible as EJB predates J2EE.

Tom, I don't know about the history - but take a look at today's docs.

EJB container is one of the containers referenced by Java EE/J2EE. I
have just had a quick look through the EJB 3.0 Public Review "EJB Core
Contracts and Requirements". While EJBs are required to be provided with
a good chunk of APIs whose specifications are also referenced by Java
EE/J2EE, I see no evidence that the EJB specification mandates Java EE/J2EE.

EJB is *part of* the J2EE spec. If you use EJB's you per def. use (a
part of) J2EE. Even JDBC, though the interfaces are distributed in the
JDK, is part of the J2EE spec. To actually use jdbc, all you need is a
driver from a vendor, and a J2SE jdk. However, you're still programming
using a J2EE api.

By your definition, every J2SE/Java SE programmer is a J2EE/Java EE
programmer. Presumably C programmers are C++ programmers as well (more
or less). Very much a recruitment agent point of view. Oh and getting
back to EricF, JMS is now J2EE/Java EE.

How about ActiveMQ for JMS?

I've done it via openjms. Tomcat does _not_ come with JMS, you need to
add it.
