      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.
