public class ThreadedOracleEpsgFactory
extends ThreadedEpsgFactory

Connection to the EPSG database in Oracle database engine using a JDBC datasource. The EPSG database can be downloaded from http://www.epsg.org. It should have been imported into an Oracle database, which doesn't need to be on the local machine.

Connection parameters

The preferred way to specify connection parameters is through the JNDI interface. However, this datasource provides the following alternative as a convenience: if a "EPSG-DataSource.properties" file is found in current directory or in the user's home directory, then the following properties are fetched. Note that the default value may change in a future version if a public server becomes available.

Property Type Description Geotools Default
serverName String Oracle database server host name localhost
databaseName String Oracle database name EPSG
schema String The schema for the EPSG tables
portNumber int TCP port which the Oracle database server is listening on 1521
user String User used to make database connections GeoTools
password String Password used to make database connections GeoTools

The database version is given in the edition attribute of the authority. The Oracle database should be read only.

Just having this class accessible in the classpath, together with the registration in the META-INF/services/ directory, is sufficient to get a working EPSG authority factory backed by this database. Vendors can create a copy of this class, modify it and bundle it with their own distribution if they want to connect their users to an other database.

Constant Field Values
Constructor Detail

ThreadedOracleEpsgFactory

public ThreadedOracleEpsgFactory()
Creates a new instance of this factory.


ThreadedOracleEpsgFactory

public ThreadedOracleEpsgFactory(Hints hints)
Creates a new instance of this factory with the specified hints. The priority is set to a lower value than the FactoryOnAccess's one in order to give the priority to any "official" database installed locally by the user, when available.

Method Detail

createDataSource

protected javax.sql.DataSource createDataSource()
                                         throws java.sql.SQLException
Returns a data source for the PostgreSQL database.

Overrides:
createDataSource in class ThreadedEpsgFactory
Returns:
The EPSG data source, or null if none where found.
Throws:
java.sql.SQLException - if an error occured while creating the data source.

createBackingStore

protected AbstractAuthorityFactory createBackingStore(Hints hints)
                                               throws java.sql.SQLException
Returns the backing-store factory for Oracle syntax.

Overrides:
createBackingStore in class ThreadedEpsgFactory
Parameters:
hints - A map of hints, including the low-level factories to use for CRS creation.
Returns:
The EPSG factory using Oracle syntax.
Throws:
java.sql.SQLException - if connection to the database failed.
