org.teiid.jdbc
Class TeiidDataSource

java.lang.Object
  org.teiid.jdbc.WrapperImpl
      org.teiid.jdbc.BaseDataSource
          org.teiid.jdbc.TeiidDataSource

All Implemented Interfaces:

Serializable, Wrapper, CommonDataSource, ConnectionPoolDataSource, DataSource, XADataSource

public class TeiidDataSource
extends BaseDataSource

The Teiid JDBC DataSource implementation class of DataSource and XADataSource.

The DataSource interface follows the JavaBean design pattern, meaning the implementation class has properties that are accessed with getter methods and set using setter methods, and where the getter and setter methods follow the JavaBean naming convention (e.g., getPropertyName() : PropertyType and setPropertyName(PropertyType) : void).

The XADataSource interface is almost identical to the DataSource interface, but rather than returning Connection instances, there are methods that return XAConnection instances that can be used with distributed transactions.

The following are the properties for this DataSource:

Property Name	Type	Description
portNumber	int	The port number where a Teiid Server is listening for requests.
serverName	String	The hostname or IP address of the Teiid Server.

If "serverName" property is not set then data source will try to create a embedded connection to the Teiid server.
