Jerry Cwiklik updated UIMA-1140:
--------------------------------
Attachment: uimaj-as-core-UIMA-1140-patch.txt

Provided an alternate mechanism for messaging between colocated Uima As
services. Instead of using jms based queues the internal messaging is done via
java queues. The new messaging implementation uses java's TaskExecutor
framework which provides necessary synchronization and threading. Each Uima As
service uses a new UimaDispatcher component to send outbound messages and a
UimaListener component for receiving incoming messages. Each incoming message
is processed in a separate thread provided by the TaskExecutor. The number of
threads used by the TaskExecutor depends on the value of the
"inputQueueScaleout" attribute for incoming messages and the
"internalReplyQueueScaleout" attribute for outgoing messages. Both of these
attributes are configured in the deployment descriptor.
*******************************************************************************************************************************
NOTE: The default messaging mechanism is *still* JMS using internal Broker. To
enable java queue's for internal messaging use -DUseVmTransport=true system
property.
*******************************************************************************************************************************
Fixed Uima As controller code to enable support for colocated Aggregate Cas
Multiplier.
Merged Delta Cas changes
Added new 2 testcases
Added new API to the testcase base code to enable a testcase to pass exceptions
it wants to ignore. This prevents the Exceptions from being printed on the
stdout.
> Embedded broker should be eliminated

> When an async aggregate is deployed, the request/reply queues for colocated
> delegates use an embedded broker. After UIMA-1130 is complete, all reply
> queues for remote delegates will be located on the same external broker
> hosting the delegate's request queue. At that point the function of the
> colocated broker can be replace with simple Java queues.
