Method Details

getConnection

public Connection getConnection()
                         throws SQLException

Description copied from class: ClientPooledConnection

Creates a logical connection.

This is the standard API for getting a logical connection handle for a pooled connection. No "resettable" properties are passed, so user, password, and all other properties may not change.

Specified by:

getConnection in interface PooledConnection

Overrides:

getConnection in class ClientPooledConnection

Throws:

SQLException - if creating a new logical connection fails

getUnigueRmId

private static int getUnigueRmId()

getRmId

public int getRmId()

getXAResource

public XAResource getXAResource()
                         throws SQLException

Specified by:

getXAResource in interface XAConnection

Throws:

SQLException

close

public void close()
           throws SQLException

Description copied from class: ClientPooledConnection

Closes the physical connection to the data source and frees all associated resources.

Specified by:

close in interface PooledConnection

Overrides:

close in class ClientPooledConnection

Throws:

SQLException - if closing the connection causes an error. Note that this connection can still be considered closed even if an error occurs.
