Max, yes, you are right, you clarified that at the end.

On the subject of VisualVM I think there's a typo: "For explicit jmx agent connection use: -J -Djconsole.plugin.path=path to the jconsole plugin" I believe the jconsole.plugin.path is here to specify the path to the legacy jconsole plugin that you would like to import into VisualVM. You would also need to have downloaded & installed the JConsole plugin container from the VisualVM update center - see https://visualvm.dev.java.net/plugins.html Cheers, -- daniel Hi,

And if you move between providers don't just do it blindly - make sure you test it ;) Shaun,

Alex said that he never used EclipseLink so he cannot commend on that. When he referred to incompliances he did it with regards to TopLink.

TopLink Essentials is the JPA 1.0 reference implementation and EclipseLink is the JPA 2.0 reference implementation. We've had developers migrating from Hibernate to EclipseLink discover their code didn't run because EclipseLink was very spec compliant. Perhaps Alex misunderstood our lack of support for Hibernate-isms as non-spec compliance? ;-) --Shaun I find Alex Snaps’ response to your question about comparing Hibernate with TopLink or EclipseLink a little funny.

TopLink Essentials is the JPA 1.0 reference implementation and EclipseLink is the JPA 2.0 reference implementation. We’ve had developers migrating from Hibernate to EclipseLink discover their code didn’t run because EclipseLink was very spec compliant.
