Is Container Managed Transactions possible in case of Tomcat ?
I planning to use JPA (Hibernate) in a small project that I am developing.
Now I have heard a lot about the benefits of using Container Managed
Transactions(CMT) for JPA in web apps. But most of the tutorials on the web
use either GlassFish or JBoss, so I was wondering is CMT supported by
Tomcat. Send me a link to the documentation for this if there is any.
Please note that I am going to use a datasource to connect to my database
and I am using persistence.xml(JPA style) to use Hibernate.

By container managed transactions I mean can I do the following in Tomcat
not TomEE
@PersistenceContext
EntityManager em;
Is it possible to have the entity manager injected at runtime in Tomcat
with JOTM or Atomikos?

Yes since Apache TomEE is Java EE 6 certified it can runs with any JPA
provider. As suggested you can use previous links for this. It is really
simple. Also briefly Apache TomEE 7 M1 (Java EE 7 compatible) will be
released.
As mentioned subscribe to TomEE mailing list or you can contact myself
without any problem.

TomEE supports Apache OpenJPA. What if I wanted to use Hibernate as my JPA
provider ?

Yeah in this case you should take a look at Apache TomEE which is Apache
Tomcat + Java EE and you will get all of these for free :).

If you're referring to JTA, then no. Tomcat doesn't implement that.
Tomcat only implements a subset of the JEE spec.
http://tomcat.apache.org/whichversion.html
However most of the parts of the spec that Tomcat does not implement can be
pulled in via libraries. For JTA you can use a third party implementation
with Tomcat. Atomikos, JOTM and Bitronix are ones that come to mind.
These docs are a little dated, but should get you started.
