> Add Connection Factory configuration properties to PublishJMS and ConsumeJMS
> processors
> ---------------------------------------------------------------------------------------
>
> Key: NIFI-7226
> URL: https://issues.apache.org/jira/browse/NIFI-7226
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Extensions
> Reporter: Peter Turcsanyi
> Assignee: Peter Turcsanyi
> Priority: Major
> Fix For: 1.12.0, 1.11.4
>
> Time Spent: 3h 10m
> Remaining Estimate: 0h
>
> Connection factories can be configured via JndiJmsConnectionFactoryProvider
> or JMSConnectionFactoryProvider controller services for PublishJMS /
> ConsumeJMS.
> However, some JMS client libraries may not work with the controller services.
> For example WebLogic JMS client throws the following exception when receiving
> a certain type of messages:
> {code:java}
> java.lang.ClassCastException:
> weblogic.diagnostics.context.DiagnosticContextImpl cannot be cast to
> weblogic.workarea.WorkContext
> {code}
> This is due to incompatible Java ClassLoader handling between the WebLogic
> JMS client library and NiFi. NiFi applies classloader isolation between its
> components. Apparently there is also classloader manipulation within the
> WebLogic client. These incompatible classloader switches lead to the
> situation that some JMS client classes are loaded by the controller service's
> classloader, while others by the WebLogic's custom classloader (which is a
> child of the processor's classloader, so it is on a different branch in the
> classloader hierarchy than the controller service).
> The issue can be eliminated by using the processor's classloader to load the
> JMS client classes instead of the controller service's. This can be achieved
> via configuring the connection factory on the processor itself.
