I have it figured out. I was referring to the wrong PU
when I switched to using @PersistenceContext.
Thanks
Kevin,
Looks like CpUser has not been loaded
into the session for the SQLServer PU, check your persistence.xml that should be
referencing the following class - verify that you have a <class>com.gmrc.jpa.domain.CpUser</class> inside - "all"
entities must be listed now if you are overriding exclude-unlisted-classes on
the container.
Exception
Description: Missing descriptor for [class
com.gmrc.jpa.domain.CpUser].
thank
you

OK, I was able to add that element and it did seem to help
out with the slowing down of the load time after each restart. But I am
having a new issue.
I have 2 different JPA jars defined with in my
project. One has a persistence unit that points to a Websphere
datasource using DB2 database running on iSeries, and the other is Websphere
datasource pointing to a SQLServer database. Looks like if I just hit
the DB2 database, everything works like it should. But when I try and
use the sqlserver persistence units I get an error.

Kevin,
Very good you will be
able to use both dynamic (default) and static weaving.
For your reference here is part of a tutorial and a previous eclipselink-users
discussion on the exclude-unlisted-classes element.
An example of EE
usage of the exclude-unlisted-classes element.

Yes, I am on WAS 6.1 with the EJB3 feature pack. I
will give that setting a try next. Thanks
Kevin,
Hi, there are several
solutions, A fellow developer Tom reminded me of some settings you may
use.
If you would like to keep your configuration
as-is. Try adding
<exclude-unlisted-classes>true</exclude-unlisted-classes> to
your persistence.xml - in an EE environment this defaults to false (it
is true in an SE environment). You will need to specify all your
entities in persistence.xml if you modify this
flag.
Also what version of WebSphere are you
running? 6.1 with the ejb3 fixpack / 7 or something pre 6.1 (IE no
JEE5 support).
If you are running a version less than
6.1 then dynamic weaving will not be available
anyway.
thank you

Doing that sounds like a maintenance nightmare
for me. We have 10+ developers, 4 different test environments, and
keeping them all in synch outside of deploying it in an EAR is
problematic. I verified that I do not have any of these eclipselink
jar files located in anything other than the eclipselink.jar itself.
Any ideas on what would change between starts and stops of the
server? Initially it starts up very quickly, and degrades after each
server restart.
Khasket,
Hi, try removing
eclipselink.jar entirely from your EAR (I assume you only have 1 EAR
containing multiple WARs), and create a shared library in WebSphere to see
if this solves your issue. Before you add a shared-library, you may
verify your EAR is clean by making sure you get a provider not found
exception when you try to run EclipseLink JPA without an eclipselink.jar
library defined - as a check.
However, the fact that
you are getting classes in your WAR is odd. Verify after you remove
eclipselink.jar that there are no "org.eclipse.persistence" classes in
your expanded EAR/EJB/WAR jars and also in the deployed expanded versions
on the server - as the following class should not be in your WAR.
\LineCPP\WebContent\WEB-INF\classes\org\eclipse\persistence\internal\expressions\QueryKeyExpression.class
thank you

Khaskett,
Hi, just my small observation, but it looks like you may be
including the EclipseLink jar classes in your WAR. Since we will search
for entities in all the classes/* files, this may be the cause of your
slowdown because you are doing a predeploy() on 100's of extra classes
unrelated to your application.
It does this for all files in the persistence.xml even some eclipselink
files
\LineCPP\WebContent\WEB-INF\classes\org\eclipse\persistence\internal\expressions\QueryKeyExpression.class
I would recommend that you install EclipseLink as a shared library
that would be available to all your web projects at the higher websphere
server classpath level as a library.
See the following screen capture for WebLogic 6.1 that details how
to do this on the admin console by creating a shared library to
$server\lib\eclipselink.jar, depending on how high you want it, you may
need to deploy it to alternatively to $server\lib\ext\eclipselink.jar
http://wiki.eclipse.org/EclipseLink/Examples/JPA/WebSphere_Web_Tutorial#EclipseLink_JAR_location
If you require a separate eclipselink.jar to be in the specific war
classpath of each application then I would move it up to a lib directory
off of WebContent outside of the JPA search path.
hope this helps, thank you

The odd thing about that is it is the process is looking for this file -
\LineCPP\WebContent\WEB-INF\classes\com\gmrc\jpa\domain\CpUserroleId.class
But LineCPP is my WebProject
and the CpUserroleId.class is in my JPA project
\CpsJPA\bin\com\gmrc\jpa\domain\CpUserroleId.class
It does this for all files in the persistence.xml even some eclipselink
files
\LineCPP\WebContent\WEB-INF\classes\org\eclipse\persistence\internal\expressions\QueryKeyExpression.class
I have 9 different WebProjects and I think it searches through all of
them.
Any ideas on whats going on here?

It seems to hang for several minutes on these two lines -

Running on Websphere 6.1.0.23 with EJB3 Feature Pack installed.
Anything I can do to fix this?
