Method Detail

initialize

public void initialize(com.stc.connector.framework.eway.ManagedConnectionCallback aCallback,
                       javax.security.auth.Subject aSubject,
                       javax.resource.spi.ConnectionRequestInfo aConfiguration,
                       com.stc.connector.management.jca.system.mbeans.MonitorDataContainer aMonitorDataContainer)
                throws javax.resource.ResourceException

Initialize the EwayConnection. Establish the connection to the external system (EIS).

Specified by:

initialize in interface com.stc.connector.framework.eway.EwayConnection

Parameters:

mcCallback - The callback object for getting services from the associated ManagedConnection.

subject - The Subject instance which holds the credentials for EIS signon.

cri - The ConnectionRequestInfo instance which can hold both EIS signon information or general connection specific information. The ConnectionRequestInfo provided will contain the union of the properties from the client connection request properties, the ResourceAdapter properties, and the ManagedConnectionFactory properties.

Throws:

javax.resource.ResourceException - upon error.

getConnection

public com.stc.connector.framework.client.AssociateableHandle getConnection(javax.security.auth.Subject subject,

Get a new instance of the connection handle (application connection). If the Subject and/or ConnectionRequestInfo contains different connection establishment information, then the Eway should reauthenticate with the EIS.

Specified by:

getConnection in interface com.stc.connector.framework.eway.EwayConnection

Parameters:

subject - The Subject instance which holds the credentials for EIS signon.

cri - The ConnectionRequestInfo instance which holds both EIS EIS signon information or general connection specific information. The ConnectionRequestInfo provided will contain the union of the properties from the client connection request properties, the ResourceAdapter properties, and the ManagedConnectionFactory properties.

Returns:

A connection handle (application connection) instance which implements the Associateable interface.

Throws:

javax.resource.ResourceException - upon error.
