title: JPA/Hibernate with Oracle Label Security
body: <p>I have an application built with Spring and JPA/Hibernate that is working very well, but I now have a requirement to add Oracle Label Security. This will require the creation of a proxy user assigned with certain roles in addition to the actual user. I am unclear what goes into persistence.xml and what goes in code. Also, if we want to get really fancy, I would love to know how Spring can inject the proper persistence context with the mapping of user to proxy user.</p>
  
  <p>If anyone has experience with this, any insight is appreciated.</p>
  
  <p>thanks.</p>
