Hello all, I read on this page http://en.wikibooks.org/wiki/Java_Persistence/Advanced_Topics#Filters, some thing about filters. My understanding is that it creates multiple view for the database. I need to implement row level security depending on the user reading the data. I know this can be in done in the DAOs. But since this is going to be done in many places I am searching for a better option. Another option is to do it in Aspect Oriented way. For a moment I though about extending the EntityManager, and do what I need there. Still I believe using filters the way it's described, is a cleaner approach for what I am doing and if I understand it correctly.
Another option is http://jpasecurity.sourceforge.net/. My first question is, does openjpa has something similar ? The second question, I didn't find anything about these data filters in the specs. Which makes me conclude that it can not be done in a vendor neutral way. Am I missing something ? If anyone had experience with similar situation, please share. Thank you.
