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' - Break @ SQLManagementFactory.java Line:122
- Figure out why there is the exception (unable to lock the PostgreSQL store for the adapter - Break @ SQLDataTest.java Line:443
- 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
- The package that is being imported:
- 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
- Configure SQLSchemaManagementFactory.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
