Bryan Bende updated NIFI-2909:
------------------------------
Status: Patch Available (was: In Progress)
> Provide a framework mechanism for loading additional classpath resources
> ------------------------------------------------------------------------
>
> Key: NIFI-2909
> URL: https://issues.apache.org/jira/browse/NIFI-2909
> Project: Apache NiFi
> Issue Type: Improvement
> Reporter: Bryan Bende
> Assignee: Bryan Bende
> Fix For: 1.1.0
>
>
> We currently have several components with a property for specifying
> additional classpath resources (DBCP connection pool, scripting processors,
> JMS). Each of these components is responsible for handling this in its own
> way.
> The framework should provide a more integrated solution to make it easier for
> component developers to deal with this scenario. Some requirements that need
> to be met by this solution:
> - Multiple instances of the same component with different resources added to
> the classpath and not interfering with each other (i.e. two DBCP connection
> pools using different drivers)
> - Ability to modify the actual ClassLoader of the component to deal with
> frameworks that use Class.forName() without passing in a ClassLoader, meaning
> if a processor loads class A and class A calls Class.forName(classBName),
> then class B needs to be available in the ClassLoader that loaded the
> processor's class which in turn loaded class A
> - A component developer should be able to indicate that a given
> PropertyDescriptor represents a classpath resource and the framework should
> take care of the ClassLoader manipulation
