Hibernate version: 3.01
Container: Tomcat 5.5.9

I've removed jta.jar and now Hibernate is complaining ClassNotFoundException: javax/transaction/SystemException. I'm trying to understand why it is looking up JTA in the first place when my configuration says it should do otherwise. Here is the verbose log I see on startup:

Do you see anything in the log that would indicate why it is looking up JTA in the first place? According to hibernate/lib/readme.txt, jta.jar is optional if you run inside a container.

Thank you,
Gili

Is this because Tomcat counts as a "non-managed environment"? The readme says:

runtime, required for standalone operation (outside application server)

which is why I am expecting it to be optional, even under Tomcat. If this isn't the case I can file a bug against the documentation to explicitly refer to Tomcat.

Gili

Tomcat is not an application server. Please don't file bugs.

At the very least I'd like to file a documentation RFE so we explicitly say "Tomcat is not an application server" somewhere. I just did a text search through out online doc and we never seem to make this discuss this at all.

That paragraph I quoted for you out of Hibernate in Action is very well written. Is it possible for us to paraphrase it in the online doc?

Gili

hibernate doco doesn't have to tell you about the differences between tomcat and JBoss AS,Weblo,Websphere, you have to know what you are using, no?

Right, except that I don't consider "Tomcat is not an application server" to be common knowledge and when readme.txt says jta.jar is optional if you're running inside one, I assumed I was fine without it.

Are you telling me I am the first person to ever confuse Tomcat for an application server? :) I don't see much harm adding a small paragraph to the documentation. If it was good enough for Hibernate in Action it should be good enough for our online documentation. We already have an entire chapter dedicated to Tomcat; why not add this paragraph there?

Gili

There _is_ a whole chapter about Tomcat in the reference documentation!

Absolutely, but you will note that:

1) It does not list jta.jar as one of the dependencies, even though it is required.
2) It does not explicitly explain out that Tomcat is not a full-fledged application server but rather a servlet container which is a subset thereof.

I know this is all obvious stuff to Hibernate veterans such as yourself, but it is the first time I ever heard of it and I've been doing servlet development for a long while now. I don't mean to push, I'm only trying to help future users so they don't run into the same problems I did and hopefully help you guys as well because they won't come running to you with questions.

Because its not a requirement in some Tomcat versions. I don't intent to document Tomcat in the Hibernate reference.
