public class JPA2DataSource extends JPADataSource
Server side implementation of JPA 2.0 data source.

Supports all AdvancedCriteria criterions except "regexp" and "iregexp".

Declaring JPA 2.0 usage in persistence.xml:

     <persistence
          version="2.0"
          xmlns="http://java.sun.com/xml/ns/persistence"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
     ...
     </persistence>

Implementation is not thread-safe. Data source acquiring mechanism enshures that single instance of this class will be used in one thread only.
