          This is used to create a message endpoint.
 MessageEndpoint createEndpoint(XAResource xaResource, long timeout)
          This is used to create a message endpoint.
 boolean isDeliveryTransacted(java.lang.reflect.Method method)
          This is used to find out whether message deliveries to a target method on a message listener interface that is implemented by a message endpoint will be transacted or not.
 

Method Detail

createEndpoint

MessageEndpoint createEndpoint(XAResource xaResource)
                               throws UnavailableException
This is used to create a message endpoint. The message endpoint is expected to implement the correct message listener type.

Parameters:
xaResource - an optional XAResource instance used to get transaction notifications when the message delivery is transacted.
Returns:
a message endpoint instance.
Throws:
UnavailableException - indicates a transient failure in creating a message endpoint. Subsequent attempts to create a message endpoint might succeed.

createEndpoint

MessageEndpoint createEndpoint(XAResource xaResource,
                               long timeout)
                               throws UnavailableException
This is used to create a message endpoint. The message endpoint is expected to implement the correct message listener type.

Parameters:
xaResource - an optional XAResource instance used to get transaction notifications when the message delivery is transacted.
timeout - an optional value used to specify the time duration (in milliseconds) within which the message endpoint needs to be created by the MessageEndpointFactory. Otherwise, the MessageEndpointFactory rejects the creation of the MessageEndpoint with an UnavailableException. Note, this does not offer real-time guarantees.
Returns:
a message endpoint instance.
Throws:
UnavailableException - indicates a transient failure in creating a message endpoint. Subsequent attempts to create a message endpoint might succeed.

isDeliveryTransacted

boolean isDeliveryTransacted(java.lang.reflect.Method method)
                             throws java.lang.NoSuchMethodException
This is used to find out whether message deliveries to a target method on a message listener interface that is implemented by a message endpoint will be transacted or not. The message endpoint may indicate its transacted delivery preferences (at a per method level) through its deployment descriptor. The message delivery preferences must not change during the lifetime of a message endpoint.

Parameters:
method - description of a target method. This information about the intended target method allows an application server to find out whether the target method call will be transacted or not.
Returns:
true, if message endpoint requires transacted message delivery.
Throws:
java.lang.NoSuchMethodException - indicates that the specified method does not exist on the target endpoint.
