Jerry Cwiklik reopened UIMA-1288: --------------------------------- Assignee: Jerry Cwiklik (was: Tong Fin) When Uima AS starts up it prints: >>> Setting defaultBrokerURL to:tcp://localhost:61616 even though the brokerURL attribute references a different broker. > Need a Better Approach For Specifying UIMA AS Broker URL in Deployment > Descriptor > --------------------------------------------------------------------------------- > > Key: UIMA-1288 > URL: https://issues.apache.org/jira/browse/UIMA-1288 > Project: UIMA > Issue Type: Improvement > Components: Async Scaleout > Reporter: Jerry Cwiklik > Assignee: Jerry Cwiklik > Fix For: 2.3AS > > > Each UIMA AS deployment descriptor requires at least one Broker URL for the > connection factory. Instead of hard coding the URL, perhaps a placeholder for > it should be used. At runtime, the placeholder could be resolved to the > actual URL by Spring resolver component. The value could come from either an > external file or from an environment. The new approach should accommodate > specifying more than one placeholder, since an aggregate may have delegates > whose queues are managed by a different broker. The new approach would > simplify deployment of UIMA AS services, especially during testing. > A placeholder syntax could be inherited from Spring, where it looks like > ${placeholder-name}. > dd2spring would need to change to handle a placeholder notation in addition > to supporting hard coded broker URL that we use now. A new bean must be added > to the generated xml. It will be : > <bean > class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> > <property name="systemPropertiesModeName" > value="SYSTEM_PROPERTIES_MODE_OVERRIDE"/> > </bean> > > This bean is setup to resolve placeholders using system variables, like > -Dplaceholder-name=placeholder-value -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
