Property hibernate.transaction.manager_lookup_class automatically set when 
using Hibernate as the PersistenceProvider
---------------------------------------------------------------------------------------------------------------------

                 Key: OPENEJB-801
                 URL: https://issues.apache.org/jira/browse/OPENEJB-801
             Project: OpenEJB
          Issue Type: Improvement
          Components: configuration
    Affects Versions: 3.0, 3.0-beta-2, 3.0-beta-1
            Reporter: David Blevins
            Assignee: David Blevins
             Fix For: 3.0.1


Code is essentially:

                    String lookupProperty = 
"hibernate.transaction.manager_lookup_class";
                    String openejbLookupClass = 
"org.apache.openejb.hibernate.TransactionManagerLookup";
                    String className = 
persistenceUnit.properties.getProperty(lookupProperty);

                    if (className == null || 
className.startsWith("org.hibernate.transaction")){
                        persistenceUnit.properties.setProperty(lookupProperty, 
openejbLookupClass);
                        logger.debug("Adjusting 
PersistenceUnit(name="+persistenceUnit.name+") property to 
"+lookupProperty+"="+openejbLookupClass);
                    }

The result is that OpenEJB-specific configuration can be avoided when using 
OpenEJB + Hibernate.  A second benefit is that if another vendor is used in 
production, the value will automatically be reset for using OpenEJB in the test 
environment.  Ensuring the strategy starts with "org.hibernate.transaction" 
allows for a custom lookup strategy to be used and not overridden.
