Subject Re: How know when "Session is closed" after establish connections between uima-as client and ActiveMQ?
Date Tue, 18 Jul 2017 20:09:57 GMT
i just tested the snapshot build from
https://svn.apache.org/repos/asf/uima/uima-as/trunk, i continue using
8 service uima-as remote, 2 are used only for
aggregates services, and created 6 uima-as client instances in my
client application general.

Now the behavior is the follow:

After restart the broker, the first uima-as client that is consumed
(no matter which),
has a correct behavior, the instruccion to uima-as client
"BaseUIMAAsynchronousEngine_impl.connectionOpen()" return "false" and
correctly initializes the client again and process the request.

All next uima-as client to consume returns "true" to the instruccion
"BaseUIMAAsynchronousEngine_impl.connectionOpen()", send the request,
and then the uima-as service process the request but after shows lines
similar to this in the log

03:24:52.338 - 1283:
org.apache.uima.adapter.jms.activemq.JmsEndpointConnection_impl.UimaAsAsyncCallbackListener.onException():
INFO: Service:XCharsetDetector JMS unable to Deliver
CAS:46623412:15d57234659:-7fea -
Error:temp-queue://ID:nelson-XPS-8700-40232-1500405516005-1:1:5
03:24:52.338 - 1283:

INFO: Controller: XCharsetDetector Handling Release CAS Request.
Releasing CAS Reference Id: 46623412:15d57234659:-7fea


and then in my mechanism de timeout in client side, after 10 seconds
without get any notification  on onBeforeProcessCAS() metod of uima-as
client's UimaAsBaseCallbackListener y throws timeout exception.
