::
<source lang=java>
props.setProperty(XMLMetadataLoader.CONNECTIONS_URL_PROPERTY, "/nexj/" + sAdapter.toLowerCase(Locale.ENGLISH) + ".connections"); // sets the properties to postgresql.connection
</source>
: After all properties are loaded, it creates the connection through Connection Factory files.
* 2- Add PostgreSQL adapter type ===Files to related java filesConfigure==='''NOTE''': SQLSchemaMangerFactory.javaChanges to these files are involved with '''1-Port''', which should be: RelationalDatabaseFragment.java:: The 5432, and '''2- Driver package ''' that is being imported: should change to <code> org.postgresql.jdbc3xa.Jdbc3.SimpleDataSource PGXADataSource </code>* 3- Create a PostgreSQL database through some scripts: src: postgresql_setup: system.sqldstype:: DatabaseTool.java // This file calles SQLSchemaMangerFactory.java and creates the connection* 4- Create :: RelationalDatabase.java // Sets the default properties for the extended PostgreSQL source files supported drivers: PostgreSQLAdapter: RelationalDatabaseFragment.java// Sets the custom fragment properties for the supported drivers: PostgreSQLSchemaManger: Driver type and some other properties in JDBCInfo.java:: SQLSchemaManagerFactory.java // Sets the connection for the particular adapter type* 5- Create the extended PostgreSQL : test :: AllTests.java:: default.config // change to these four files are: adapter="PostgreSQL" port="5432": PostgreSQLAdapterTest: postgresql.connection :: filestorage.javaconnections: PostgreSQLSchemaMangerTest:filestoragefragment.javaconnections-->
