-----------------------------------
Summary: UIMA-DUCC: the WS broker health checker should create new
connection
Key: UIMA-5894
URL: https://issues.apache.org/jira/browse/UIMA-5894
Project: UIMA
Issue Type: Improvement
Components: DUCC
Reporter: Jerry Cwiklik
Assignee: Jerry Cwiklik
Fix For: 2.3.0-DUCC
Current broker health checker in the WS uses Camel's producer to send JMS pings
to itself. This producer is optimized to use Connection factory and reuse
existing connections. Although this is efficient, it does not test an important
scenario where a broker keeps serving existing connections but refuses to
accept new ones.
So to test broker viability the health checker should create new broker
connection for every ping. Spring's JmsTemplate provides such function. Modify
Camel route in WebServerConfiguration code to not publish pings. This route
should continue to run on the timer but the ping should be dispatched by new
code in WebServerStateProcessor.process().
This code will use JmsTemplate to publish WebServerStateDuccEvent to the WS
topic
