I thought that's how I could make it work. Instead, I'm getting error on
deployment. TomEE think there are two persistence units of the same name
and litters the log with errors.
When I move persistence.xml out of the jar back into the web app, I can
deploy successfully, but the entities become invisible. And even if I
add them manually to the persistence unit, it still doesn't work.
So I'm stuck with what to do. I am using 1.6.0 Web Profile, but also
tested Plus. It's just not happening for me. And I HAVE to separate
those entities so I can pick and choose development entities over live
production entities, which are slightly different.

Hi,
I usually add entities and persistence.xml (meta-inf) in a library jar.
Then u also will have metamodels generated in the lib.
Works for me.

I've done all that you said. Here's the break-down:
* Java class library project contains JUST entity classes and session
beans for them, no persistence.xml file
* Web App is "linked" with the JAR project and is being placed into
the WEB-INF/lib directory. I've inspected and confirmed this
manually by looking the the produced war file.
The application deploys without error and the log shows the session
beans being activated. But as soon the session tries to run a named
query, I'm getting error messages. Would it help if I created a smaller
test project and posted it on Github?

Where should the persistence unit be located? Inside the jar containing the
entities, or inside the web-app?

yes but you can just put entities in a jar, add it in web-inf/lib and
list your entities in your persistence unit (or use openejb scanning

Ok, here's my real problem:
We have a project that has "almost the same" database in multiple
locations.
Basically, they are different revs of a database. E.g.: my development
database which always has the latest, a production database @ customer1,
another production database @customer2. Right now, my dev database and
the
one @ customer1 are out of sync. Fields were added in dev that are not in
that customers schema.
The web-app I'm writing will have to be deployed at customer1, but the
enties I generated (with NetBeans wizard) don't match. So what I would
like
to do is separate the entity classes and session beans for them out of
the
web app and into a dedicated library. I think that dedicated library has
to
be an ejb module because if I simply mkove them into a simple java Class
Library and add that to my web app, nothing works anymore.
Do you see my need now?

We support ears but I dont follow you when you say you want it, ear are
great only if you have multiple wars in a single app.
Jpa2 metamodel can be generated with mvn so it should be great with
netbeans.

I found that NetBeans, on deployment, copied the persistence.xml file
into
the another location. I removed the Netbeans cache from my home
directory
and it stopped doing that.
That said, a new issue arose. Apparently, the auto-generated Entity
classes are not being generated anymore (the ones that end in an
underscore).
So maybe my approach as a whole is not what should be done. I read up a
little, and what would more appropriate would be to create Java EE
Enterprise module, into which I would then create sub-projects for a
WAR
and an EJB (containing entities and session beans). These would then be
packaged to an EAR. But how to do that with Tomee and Netbeans goes
beyond
the scope of my question and Netbeans doesn't properly support Tomee
yet,
meaning I can't create such a project because it only gives my
Glassfish
as
a choice. Bummer!
But, from a Tomee perspective, does it support the concept of bundled
WAR/EJB in EARs?

But why is Tomee seeing two persistence units when there is clearly
on
one
persistence.xml ? I don't get it.

Hi everyone.
I would like some professional advice on this question. I'm using
Tomee
1.6.0 Web Profile and have a working web app developed with
NetBeans
that
contains entity classes and sessions beans to access those
entities.
The
app works fine. Now I'm trying to separate these classes into a
separate
class library, but I'm hitting the error wall.
First, thing that didn't work was that another class that still
resides
the web app can't find the named queries anymore defined in the
entity
classes. Upon reading a little about it, one suggestion was that
the
persistence.xml file should be located inside the JAR file that
contains
the entities, placed in the META-INF directory. After moving the
persistence.xml into the JAR as well, I now get the following
deployment
errors: http://pastebin.com/fBFYaGKR
First, off it now sees two persistence units??? Even though I
completely
remove the persistence.xml from the web app and placed it inside
the
JAR's
META-INF directory? Also the log seems to be littered with multiple
iterations of that error message per session bean. And it would be
nice
if
it actually told me where the "two" PUs are.
And just to clarify, after I moved the PU and the entities and
session
beans to the JAR, I added the JAR project back to the web app
project,
cleaned and rebuilt the JAR project first, then the web app. And
then
deployed the web app.
So that's where I'm at right now, and I'm dumb-founded. Anybody
know
what
the best practice here is? Or is it because I'm not using Tomee
FULL
vs
Web
Profile?
Please help. Thank you, and Happy New Year.
Kay
