[news.eclipse.rt.eclipselink] Re: Eclipselink without connection pool

[Thomas Haskes <t.haskes@xxxxxxx>]

Thank you, but unfortunately this doesn't work for me either, when I do
this, I get a "No suitable Driver found" error. I'm using el in an OSGI
environment and have set the PERSISTENCEUNITPROPERTIES.CLASSLOADER
property. Without setting the user name in the emProperties (means using
the standard user which is defined on the factoryproperties) it works.

Any idea whay that happens?

As there is no property for setting the classloader at the
entitymanager, I really don't have a clue why this is happening.
