public interface ResourceAdapter
|Modifier and Type||Method and Description|
This is called during the activation of a message endpoint.
This is called when a message endpoint is deactivated.
This method is called by the application server during crash recovery.
This is called when a resource adapter instance is bootstrapped.
This is called when a resource adapter instance is undeployed or during application server shutdown.
void start(BootstrapContext ctx) throws ResourceAdapterInternalException
During this method call a ResourceAdapter JavaBean is responsible for initializing the resource adapter instance. Any exception thrown during this method call causes the application server to abort the bootstrap procedure for this specific resource adapter instance.
ctx- a bootstrap context containing references to useful facilities that could be used by a resource adapter instance.
ResourceAdapterInternalException- indicates bootstrap failure. The resource adapter instance is unusable and must be discarded.
During this method call, a ResourceAdapter JavaBean is responsible for performing an orderly shutdown of the resource adapter instance. Any exception thrown by this method call does not alter the processing of the application server shutdown or resource adapter undeployment that caused this method call. The application server may log the exception information for error reporting purposes.
void endpointActivation(MessageEndpointFactory endpointFactory, ActivationSpec spec) throws ResourceException
Endpoint activation is deemed successful only when this method completes successfully without throwing any exceptions.
void endpointDeactivation(MessageEndpointFactory endpointFactory, ActivationSpec spec)
Any exception thrown by this method is ignored. After this method call, the endpoint is deemed inactive.
endpointFactory- a message endpoint factory instance.
spec- an activation spec JavaBean instance.
XAResource getXAResources(ActivationSpec specs) throws ResourceException
ActivationSpecJavaBeans and returns an array of
XAResourceobjects each of which represents a unique resource manager. The resource adapter may return null if it does not implement the
XAResourceinterface. Otherwise, it must return an array of
XAResourceobjects, each of which represents a unique resource manager that was used by the endpoint applications. The application server uses the
XAResourceobjects to query each resource manager for a list of in-doubt transactions. It then completes each pending transaction by sending the commit decision to the participating resource managers.
specs- an array of
ActivationSpecJavaBeans each of which corresponds to an deployed endpoint application that was active prior to the system crash.
XAResourceobjects each of which represents a unique resource manager.
ResourceException- generic exception if operation fails due to an error condition.
