NexJ Express Connecting to PostgreSQL

PostgreSQL Adapter for NexJ - Create Test Environment

1- Setup the postgresql-connection

• TODOs

Create and Configure the work/ws/core/test/nexj/postgresql.config

for now, the contents of default.config is changed to postgresql specifications instead of mysql

walk-through lines from 214-218 in SQLManagementConnectionFactory.java

Walk-through properties and see what exactly is needed to be authorized to connect to 'test' database

Make sure the model connects to the PostgreSQL using user 'test'

• Done

Configure the work/ws/core/test/nexj/postgresql.connection

Load the driver from RelationalDatabaseFragment.java

The package that is being imported: org.postgresql.xa.PGXADataSource

Load metadata from the particular driver

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

   /* SQLDataTest.java */
   protected static Metadata loadMetadata(String sAdapter)
   {
      Properties props = SysUtil.getConfigProperties();  // sets DEFAULT_CONFIG_URL = '/' + NAMESPACE + "/default.config"
      props = new Properties(props);
      props.setProperty(XMLMetadataLoader.CONNECTIONS_URL_PROPERTY, "/nexj/" + sAdapter.toLowerCase(Locale.ENGLISH) + ".connections");  // sets the properties to postgresql.connection

Configure system.dstype

Configure DatabaseTools.java // This file calles SQLSchemaMangerFactory.java and creates the connection

Configure RelationalDatabase.java SQLRAConnectionFactory.java

Configure Driver type and some other properties in JDBCInfo.java

2- Add PostgreSQL adapter type to related java files

SQLSchemaMangerFactory.java

3- Create a PostgreSQL database through some scripts

postgresql_setup.sql

4- Create the extended PostgreSQL source files

PostgreSQLAdapter.java

PostgreSQLSchemaManger.java

5- Create the extended PostgreSQL test files

PostgreSQLAdapterTest.java

PostgreSQLSchemaMangerTest.java
