Constructor Detail

LDAPApplicationConnection

public LDAPApplicationConnection(com.stc.connector.framework.eway.ManagedConnectionCallback mcCallback)

Creates a new instance of LDAPApplicationConnection.

Parameters:

mcCallback - The ManagedConnectionCallback for getting services from ManagedConnection.

Method Detail

close

public void close()
           throws com.stc.connector.appconn.common.ApplicationConnectionException

Closes the application connection handle. Once the close method is called, using the application created from the application connection must be forbidden and must result in an ApplicationConnectionException. The association between an application connection and the application is implementation specific.

Specified by:

close in interface com.stc.connector.appconn.common.ApplicationConnection

Throws:

com.stc.connector.appconn.common.ApplicationConnectionException - upon error.

createApplication

public java.lang.Object createApplication(java.lang.String appName)
                                   throws com.stc.connector.appconn.common.ApplicationException

Creates an Application from the Application Connection. The application is an API which can be used to interact with the underlying EIS. The application API must be invalidated once the close method is called on the Application Connection. If null is passed for the application name, then the default application will be created. Otherwise, the application name will be used to create the appropriate connection.

Specified by:

createApplication in interface com.stc.connector.appconn.common.ApplicationConnection

Parameters:

appName - The name of the application to create.

Returns:

A java.lang.Object representing the EIS specific application component to interact with the EIS.

Throws:

com.stc.connector.appconn.common.ApplicationException - upon error.

createOutputHandler

public com.stc.connector.appconn.common.OutputHandler createOutputHandler()
                                                                   throws com.stc.connector.appconn.common.ApplicationException

Creates an OutputHandler for "sending" data to the EIS. If the eWay does not support an OutputHandler, then it should return null for its implementation of this method.

Specified by:

createOutputHandler in interface com.stc.connector.appconn.common.ApplicationConnection

Returns:

The eWay specific OutputHandler for handling "sending" data to the external system or null if the eWay does not have an OutputHandler.

Throws:

com.stc.connector.appconn.common.ApplicationException - upon error.

invalidateConnection

public void invalidateConnection()
                          throws javax.resource.ResourceException

This is called by the ManagedConnection to invalidate the connection handle.

Specified by:

invalidateConnection in interface com.stc.connector.framework.client.AssociateableHandle

Throws:

javax.resource.ResourceException - upon error.

reassociateConnection

public void reassociateConnection(com.stc.connector.framework.eway.ManagedConnectionCallback mc)
                           throws javax.resource.ResourceException

This is called by the ManagedConnection to associate the connection handle to the ManagedConnection. The implementation should disassociate the associated ManagedConnection and associate itself to the ManagedConnection passed in as the argument.

Specified by:

reassociateConnection in interface com.stc.connector.framework.client.AssociateableHandle

Parameters:

mc - The ManagedConnection instance with which the connection handle will associate.

Throws:

javax.resource.ResourceException - upon error.

checkIfClosed

protected boolean checkIfClosed()

Check whether the Connection instance was already closed (if close was previously called).

Returns:

true if already closed, false otherwise.

getEwayConnection

protected LDAPEwayConnection getEwayConnection()

Get the ManagedConnection associated with this application connection.

Returns:

The ManagedConnection instance associated with this application connection.
