/* MySQLAdapterTest.java */ try { s_metadata = loadMetadata(ADAPTER_NAME); }  /* SQLDataTest.java*/

Properties props = SysUtil.getConfigProperties(); // sets DEFAULT_CONFIG_URL = '/' + NAMESPACE + "/default.config"

props.setProperty(XMLMetadataLoader.CONNECTIONS_URL_PROPERTY, "/nexj/" + sAdapter.toLowerCase(Locale.ENGLISH) + ".connections"); // sets the properties to postgresql.connection is hardcoded

* 2- Add PostgreSQL database to related java files: SQLSchemaMangerFactory.java: RelationalDatabaseFragment.java * 3- Create After all properties are loaded, it creates the extended PostgreSQL source connection through Connection Factory files : PostgreSQLAdapter.java: PostgreSQLSchemaManger.java

* 4===Files to Configure==='''NOTE''': Changes to these files are involved with '''1- Create Port''', which should be: 5432, and '''2- Driver package''' that should change to <code> org.postgresql.xa.PGXADataSource </code>: src:: system.dstype:: DatabaseTool.java // This file calles SQLSchemaMangerFactory.java and creates the connection:: RelationalDatabase.java // Sets the default properties for the supported drivers:: RelationalDatabaseFragment.java // Sets the custom fragment properties for the supported drivers:: Driver type and some other properties in JDBCInfo.java:: SQLSchemaManagerFactory.java // Sets the extended PostgreSQL connection for the particular adapter type: test :: AllTests.java:: default.config // change to these four files are: adapter="PostgreSQL" port="5432":: postgresql.connection : PostgreSQLAdapterTest: filestorage.javaconnections: PostgreSQLSchemaMangerTest:filestoragefragment.javaconnections-->
