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?

Odd, it may not be this lines causing the hang though, it could be
anything the occurs in between. Try using a Java profiler such as
JProfiler to determine where the bottleneck is.

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

In my application I have two seperate JPA utility projects one for DB2
and the other for SQL Server. The each have their own Mapping file
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?
