RepositoryException

getDataSource

public DataSource getDataSource(String logicalName)
                         throws RepositoryException

Retrieves a configured data source by logical name.

Parameters:

logicalName - the name of the DataSource

Returns:

a DataSource

Throws:

RepositoryException - if there is no DataSource with the given name

getDataBaseType

public String getDataBaseType(String logicalName)
                       throws RepositoryException

Parameters:

logicalName - the name of the DataSource

Returns:

the configured database type

Throws:

RepositoryException - if there is no DataSource with the given name

getDataSource

public DataSource getDataSource(String driver,
 String url,
 String user,
 String password)
                         throws RepositoryException,
SQLException

Retrieve a DataSource for the specified properties. This can be a JNDI Data Source as well. To do that, the driver class name must reference a javax.naming.Context class (for example javax.naming.InitialContext), and the URL must be the JNDI URL (for example java:comp/env/jdbc/Test).

Parameters:

driver - the JDBC driver or the Context class

url - the database URL

user - the user name

password - the password

Returns:

the DataSource

unwrap

public static Connection unwrap(Connection con)
                         throws SQLException

Needed for pre-10R2 Oracle blob support....:( This method actually assumes that we are using commons DBCP 1.2.2.

Parameters:

con - the commons-DBCP DelegatingConnection to unwrap

Returns:

the unwrapped connection

Throws:

SQLException
