Apache Derby Driver Adapter

Apache Derby Driver Adapter

Jul 11, 2016

Usage

The Pax JDBC Apache Derby Driver Adapter registers a DataSourceFactory in the OSGi service registry, adapting implementation classes from the Derby Embedded Driver, which is an OSGi bundle and does not need to be wrapped.

The DataSourceFactory methods of this adapter produces objects with the following implementation classes:

  • EmbeddedDriver

  • EmbeddedDataSource40

  • EmbeddedConnectionPoolDataSource40

  • EmbeddedXADataSource

Service Properties

The Derby Driver Adapter registers its DataSourceFactory with the following service properties:

  • osgi.jdbc.driver.class = org.apache.derby.jdbc.EmbeddedDriver

  • osgi.jdbc.driver.name = derby

Method Arguments

The argument passed to createDataSource(), createConnectionPoolDataSource(), createXADataSource() supports the following properties:

  • DataSourceFactory.JDBC_DATABASE_NAME (mandatory)

  • DataSourceFactory.JDBC_USER

  • DataSourceFactory.JDBC_PASSWORD

An SQLException is thrown if a mandatory property is missing. Other properties than the ones listed above will be passed directly to the underlying JDBC driver.

createDriver()

This method returns an instance of EmbeddedDriver. Any properties passed to this method are ignored.

Obtaining a DataSourceFactory

To obtain a DataSourceFactory, use any OSGi service lookup or injection method (Declarative Services, Blueprint) of your choice and specify the following properties:

  • objectClass = org.osgi.service.jdbc.DataSourceFactory

and at least one of

  • osgi.jdbc.driver.class = org.apache.derby.jdbc.EmbeddedDriver

  • osgi.jdbc.driver.name = derby

Required Maven Artifacts

  • org.ops4j.pax.jdbc:pax-jdbc-derby

  • org.apache.derby:derby

  • org.osgi:org.osgi.enterprise:4.2.0

  • An OSGi 4.2 framework
