Basic question about UIMA as service deployment

[Yamen Ajjour <ya...@gmail.com>]

Hello ,

I have a node on which I want to deploy an asynchronous analysis engine.
After running ActiveMq broker there I deployed the analysis engine on that
machine from the client as specified in the specification. Even though
everything seems to be working correclty I got the feeling that the
analysis engines are still running in my the client's JVM and not on the
node only the queue seems to be running there . Is deploying a UIMA as
service implies its execution on the computer where the broker is ?

Cheers,
Yamen

Hello Yamen, you can deploy uima-as service on a node which does not have a
broker. One of the benefits of JMS is location transparency. The broker can
run on any node in a cluster and mediates messages between client(s) and
service(s). A service connects to a broker and registers its queue. Client
which needs the service creates a connection to the same broker and sends
messages to the service queue.

The uima-as client deploy function does not exec a service process. It
actually deploys a service in the same jvm. To externalize the service use
$UIMA_HOME/bin/deployAsyncService.sh script and provide your deployment
descriptor with appropriate values for endpoint name and brokerURL. The
following is a relevant xml snippet from a deployment descriptor:

<inputQueue endpoint="<Queue Name>"  brokerURL="${defaultBrokerURL}"/>"/>
