Class JDBCConnection

java.lang.Object
  com.bankframe.ei.txnhandler.connector.jdbcconnector.JDBCConnection

All Implemented Interfaces:

EConnection

public class JDBCConnection

extends java.lang.Object

implements EConnection

JDBCConnection is an implementation of the interface EConnection. It represents an application-level handle that is used by a client such as EJB to access a database. The actual physical connection associated with a JDBCConnection instance is represented by a JDBCConnectionConnection instance.

A client gets a JDBCConnection instance by using the getConnection method on a JDBCConnectionFactory instance.

Field Summary

static java.lang.String

CONNECTOR_NAME

Constructor Summary

JDBCConnection()
JDBCConnection constructor without arguments.

JDBCConnection(JDBCManagedConnection jdbcmanagedconnection)
JDBCConnection constructor with a Managed Connection as an argument.

Method Summary

void	close() This method informs ManagedConnection the connection is closed from this class.
java.util.Vector	makeSQLQuery(java.sql.Connection con, java.lang.String sqlString) This method is used to do a database query
java.util.Vector	makeSQLUpdate(java.sql.Connection con, java.lang.String sqlString) This method is used to preform an database update
java.lang.Object	post(java.lang.Object obj) This method is where the request gets passed to the Database.

Constructor Detail

JDBCConnection

public JDBCConnection()

JDBCConnection constructor without arguments.

JDBCConnection

public JDBCConnection(JDBCManagedConnection jdbcmanagedconnection)

JDBCConnection constructor with a Managed Connection as an argument.

Parameters:

jdbcmanagedconnection - a JDBCManagedConnection

Method Detail

close

public void close()

This method informs ManagedConnection the connection is closed from this class. So the connector will be sent back to the pool.

Specified by:

close in interface EConnection

makeSQLQuery

                                     java.lang.String sqlString)
                              throws java.lang.Exception

This method is used to do a database query

Parameters:

con - a JDBC Connection

sqlString - a String containing the sql command

Returns:

the database response

                               throws java.lang.Exception

This method is used to preform an database update

Parameters:

con - a JDBC Connection

post

public java.lang.Object post(java.lang.Object obj)
                      throws ProcessingErrorException

This method is where the request gets passed to the Database.

Specified by:

post in interface EConnection

Parameters:

obj - An object representing a transaction that will be forwarded on to the host system by the Connector imnplementation.
