Constructor Detail

UniJDBCDataSource

public UniJDBCDataSource()
                  throws java.sql.SQLException

Allocates an empty UniJDBCDataSource object.

Throws:

java.sql.SQLException - if error is encountered while instantiating the object.

UniJDBCDataSource

public UniJDBCDataSource(UniJDBCConnectionPoolDataSource lcpds)
                  throws java.sql.SQLException

Allocates an UniJDBCDataSource object using the properties of the input ConnectionPoolDataSource.

Parameters:

lcpds - the ConnectionPoolDataSource object that contains the properties needed to make the physical connection.

Throws:

java.sql.SQLException - if error is encountered while instantiating the object.

UniJDBCConnectionPoolDataSource

Method Detail

getConnection

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

Attempts to establish a connection to the data source that this DataSource object represents.

Specified by:

getConnection in interface javax.sql.DataSource

Throws:

java.sql.SQLException - if a database-access error occurs.

getConnection

public java.sql.Connection getConnection(java.lang.String luser,
                                         java.lang.String lpassword)
                                  throws java.sql.SQLException

Attempts to establish a connection to the data source that this DataSource object represents.

Specified by:

getConnection in interface javax.sql.DataSource

Parameters:

user - the data source user on whose behalf the connection is being made.

password - the user's password.

Throws:

java.sql.SQLException - if a database-access error occurs.

getReference

public javax.naming.Reference getReference()
                                    throws javax.naming.NamingException

This method implements the Referenceable interface. Perhaps it should be called, makeReference. It is used by the naming service provider to create a reference object that embodies enough information about this datasource such that the datasource can be recreated when naming.lookup() is called. This reference is only used internally by the naming service. It is eventually bound to a user specified name (in naming.bind()) and subsequently, it is used to reconstruct the datasource when naming.lookup() is called with the given name.

Specified by:

getReference in interface javax.naming.Referenceable

Returns:

reference to the datasource.

getCPMFreeCount

public int getCPMFreeCount()

getCPDS

public UniJDBCConnectionPoolDataSource getCPDS()
