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.

The
SqlServer persistence unit is trying to call a stored procedure. In
fact that's all I use it for.
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?

In my application I have two seperate JPA utility projects one for DB2

listed
in the persistence.xml
<mapping-file>META-INF/cps-orm.xml</mapping-file>
and
<mapping-file>META-INF/sql-orm.xml</mapping-file>
Running on Websphere 6.1.0.23 with EJB3 Feature Pack installed.
Anything I can do to fix this?
