Repository did not starte due Java Deployment rule set

Dear all,

I installed a new version of java (1.7.0_67) and could not start Repository or Directory anymore.

I added the URLs of the PI sever in the white list of java panel (Tab security) with URL   http://<host>:51000/rep/  or

http://<host>:51000/

and set security level to middle, but if I would like to start the repository I got an error

that it is blocked due Deployment Rule set and that the JAR File could not be verified.

Any ideas whats going wrong? Perhaps some old configuration of my old java version left?

Regards

Chris
