Roberto Cortez commented on OPENJPA-2554:
-----------------------------------------

To support the Schema Generation specified in JPA 2.1:

Add relevant properties to 
<b>org.apache.openjpa.jdbc.conf.JDBCConfigurationImpl</b>:

{code:java}
        public IntValue databaseAction;
        ...
        databaseAction = 
addInt("javax.persistence.schema-generation.database.action");
        aliases = new String[] {
            "none", String.valueOf(SchemaGeneration.NONE),
            "create", String.valueOf(SchemaGeneration.CREATE),
            "drop-and-create", String.valueOf(SchemaGeneration.DROP_AND_CREATE),
            "drop", String.valueOf(SchemaGeneration.DROP)
        };
        databaseAction.setAliases(aliases);
        databaseAction.setDefault(aliases[0]);
        databaseAction.setAliasListComprehensive(true);
{code}

And map the new properties to a SchemaTool command in 
org.apache.openjpa.jdbc.kernel.JDBCBrokerFactory like this:

{code:java}
    private void schemaGenerationToSynchronizeMappings(JDBCConfiguration conf) {
        if (conf.getDatabaseAction() != null) {
            if (conf.getDatabaseActionConstant() == 
SchemaGeneration.DROP_AND_CREATE) {
                
conf.setSynchronizeMappings("buildSchema(ForeignKeys=true,SchemaAction='drop,add')");
            }
        }
    }
{code}

Am I following the right path here? Any others suggestions? SchemaTool is 
probably going to need a way to execute SQL scripts.
