[opencms-dev] JPA driver for 7.5.2

[Yves Glodt]

Hi!

I think there should be no simultaneous logins... But I can not be sure if
some people left a browser somewhere open with a logged session...

Good news about jpa 2.0, I will wait for that. Hopefully I can upgrade 7.5.2
by just replacing the relevant jars... :-)
