Permission error accessing keystore from Java mapping

Hi Gurus!

     Im trying to access a view from the keystore inside a java mapping, but im having the following error:

It says that user J2EE_GUEST does not have a permission, but im not configuring that user in the mapping. It is a default user that PI uses for all the access to the keystore?

What should I do in order to grant access to this user?

Ive seen many posts with this problem but they are not answered.

Thanks in advance!

Regards.
