Re: [eclipselink-users] Slow load time
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.

files
\LineCPP\WebContent\WEB-INF\classes\org\eclipse\persistence\internal\expressions\QueryKeyExpression.class
</quote>

    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.

When I start up the server for the first time the load time is very

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?
