Hi Tom
Thanks for pointing out the insufficiency of the code.
Since I am not doing any customizations should I consider using org.eclipse.persistence.jpa.PersistenceProvider.
Will that be a reasonable substitute?
Are there any examples / documentation available for creating Custom
Persistence Providers. Most of the documentation I could find is
about persistence.xml.
Thanks
Rohit

Hi
Rohit,
To be honest, I am surprised such a sparse implementation of
PersistenceProvider with such a sparsely populated instance of
SEPersistenceUnitInfo works. If you are implementing your own
persistence provider you will definitely have to do more work with
things like the classloader than the typical user. As an initial
step, it is probably a good idea to take a look at every property
of PersistenceUnitInfo and make sure you set it correctly.

Hi Tom
Class.forName() does not throw the same exception.
I figured out another way to ensure that the Class Loader is
picked up correctly.
SEPersistenceUnitInfo puInfo = new
SEPersistenceUnitInfo();
puInfo.setClassLoader(MyLogger.class.getClassLoader());
EntityManagerSetupImpl.predeploy() contains the following line
to merge the properties:
Map predeployProperties =
mergeMaps(extendedProperties,
persistenceUnitInfo.getProperties());
The properties member variable of SEPersistenceUnitInfo and the
actual member variables like classLoader are not in sync with
each other.
Though the setClassLoader method registers the class loader a
call to setProperties() on the SEPersistenceUnitInfo does not
populate the classLoader member variable.
As a result the realClassLoader field in
EntityManagerSetupImpl.predeploy() is null.
puInfo.setClassLoader(MyLogger.class.getClassLoader());
I am not sure whether my implementation of PersistenceProvider
is correct or not. Can you please see if I am missing something
else in MyPersistenceProvider code I sent earlier?
Thanks

My best guess about your logger is that
the string you are passing in isn't formatted correctly
(likely due to the fact that it is an inner class). To debug:
- try using a non-inner class to see if you're getting the
right loader
- Ensure you can do a Class.forName() using that string to see
if the string is correct

Hi Tom
Yes that was a slip in my test code. Sorry about that. So
the properties are inherited by default.
Other than that instead of using SessionCustomizer I am
planning to use "eclipselink.logging.logger" to configure my
CustomLogger. But I am getting Class not found exceptions.
The CustomLogger is a public static class nested inside the
main class. Any ideas what could be causing this? I don't
know what to specify in the class loader property. I tried
setting it to
System.getProperty("|java.system.class.loader|"). does not
work.

Hi Rohit,
The only call I see to setLogLevel in your example is on
line 73. It sets the log level on the clientSession. Am
I missing something?
A clientSession will have the same logger as the server
session that created it, so any logging settings should be
the same between the sessions.
SessionCustomizers don't really make sense on
ClientSession since the things you are likely to set in
them are all handled by the server session.
Is there some other setting that is causing you
problems?

Hi All
I have a small question. I have attached a sample
program to make it easy to see the problem.
I have set the LogLevel property on the ServerSesssion.
However if I do not explicitly set the LogLevel property
on the clientSession, the logs for the query execution
are not available on the console. I want a way such that
any property specified on the server session, say
SessionCustomizer, Log Level etc. is also available on
the client session automatically. Can anyone please tell
me how to do that using the sample code provided?
