Method Detail

setUrl

public void setUrl(java.lang.String url)

Set the JDBC URL to use for connecting through the Driver.

See Also:

Driver.connect(String, java.util.Properties)

getUrl

public java.lang.String getUrl()

Return the JDBC URL to use for connecting through the Driver.

setUsername

public void setUsername(java.lang.String username)

Set the JDBC username to use for connecting through the Driver.

See Also:

Driver.connect(String, java.util.Properties)

getUsername

public java.lang.String getUsername()

Return the JDBC username to use for connecting through the Driver.

setPassword

public void setPassword(java.lang.String password)

Set the JDBC password to use for connecting through the Driver.

See Also:

Driver.connect(String, java.util.Properties)

getPassword

public java.lang.String getPassword()

Return the JDBC password to use for connecting through the Driver.

setConnectionProperties

public void setConnectionProperties(java.util.Properties connectionProperties)

Specify arbitrary connection properties as key/value pairs, to be passed to the Driver.

Can also contain "user" and "password" properties. However, any "username" and "password" bean properties specified on this DataSource will override the corresponding connection properties.

See Also:

Driver.connect(String, java.util.Properties)

getConnectionProperties

public java.util.Properties getConnectionProperties()

Return the connection properties to be passed to the Driver, if any.

getConnection

public java.sql.Connection getConnection()
                                  throws java.sql.SQLException

This implementation delegates to getConnectionFromDriver, using the default username and password of this DataSource.

Throws:

java.sql.SQLException

See Also:

getConnectionFromDriver(String, String), setUsername(java.lang.String), setPassword(java.lang.String)

getConnection

public java.sql.Connection getConnection(java.lang.String username,
                                         java.lang.String password)
                                  throws java.sql.SQLException

This implementation delegates to getConnectionFromDriver, using the given username and password.

Throws:

java.sql.SQLException

See Also:

getConnectionFromDriver(String, String)

getConnectionFromDriver

protected java.sql.Connection getConnectionFromDriver(java.lang.String username,
                                                      java.lang.String password)
                                               throws java.sql.SQLException

Build properties for the Driver, including the given username and password (if any), and obtain a corresponding Connection.

Parameters:

username - the name of the user

password - the password to use

Returns:

the obtained Connection

Throws:

java.sql.SQLException - in case of failure

See Also:

Driver.connect(String, java.util.Properties)

                                                        throws java.sql.SQLException

Obtain a Connection using the given properties.

Template method to be implemented by subclasses.

Parameters:

props - the merged connection properties

Returns:

the obtained Connection

Throws:
