Interface MovingAverageJDBCHome

All Superinterfaces:

EJBHome, Remote

public interface MovingAverageJDBCHome

extends EJBHome

Home interface of the MovingAverageJDBC Enterprise JavaBean. Use this interface to establish a JDBC connection to your database, by specifying the following when invoking the creation methods:

• Driver Name

  The name of the driver distributed by your DBMS vendor. For example, if you wish to connect to Oracle9i the driver name you will use will be "oracle.jdbc.driver.OracleDriver".

• URL

  The url is database vendor specific as well and will describe the name of the server, the database port number and maybe a service name. Under Oracle9i the URL you would use would have the following format:

  jdbc:oracle:thin:@servername:1521:service

• Username and Password

  The username and password are in most cases indispensable when connecting to any database.

• Properties

  This variable may be left null in most cases. It should be used in order to transfer properties additional to username and password.

This home interfaces defines every method from the MovingAverageHome home interface with either one input/output database connection or two different input and output database connections. It also provides a create method which uses your Application Server DataSource Connection Pools as defined at deployment time. Every connection is defined as described above.

Method Summary

MovingAverageJDBC	create() Creates a MovingAverageJDBC bean that encapsulates a MovingAverage instance and allows you to invoke SQL queries on every of its methods using its internal jdbc/MovingAverageInputDB and jdbc/MovingAverageOutputDB DataSource references.
MovingAverageJDBC	create(String driverName, String url, String user, String password, Properties info) Creates a MovingAverageJDBC bean that encapsulates a corresponding MovingAverage component.
MovingAverageJDBC	create(String inputDriverName, String inputURL, String inputUser, String inputPassword, Properties inputInfo, String outputDriverName, String outputURL, String outputUser, String outputPassword, Properties outputInfo) Creates a MovingAverageJDBC bean that encapsulates a corresponding MovingAverage component.

Method Detail

create

public MovingAverageJDBC create()
                         throws SQLException,
                                CreateException,
                                RemoteException

Creates a MovingAverageJDBC bean that encapsulates a MovingAverage instance and allows you to invoke SQL queries on every of its methods using its internal jdbc/MovingAverageInputDB and jdbc/MovingAverageOutputDB DataSource references. This method does not require JDBC Connection properties as it relies on the Input and Output JDBC DataSource references configured at deployment time.

Notice that this creation method has the same parameters as the creation method from the MovingAverage component.

Parameters:

inputDriverName - The name of the driver used for the input connection.

inputURL - The URL that describes the input connection address.

inputUser - The input connection username.

inputPassword - The input connection password.

inputInfo - Additional input connection properties, null for none.

outputDriverName - The name of the driver used for the output connection.

outputURL - The URL that describes the input connection address.

outputUser - The output connection username.

outputPassword - The output connection password.

outputInfo - Additional output connection properties, leave null for none.
