All Implemented Interfaces:

ConfigurableComponent, ControllerService, JMSConnectionFactoryProviderDefinition

@Tags(value={"jms","jndi","messaging","integration","queue","topic","publish","subscribe"})
 @CapabilityDescription(value="Provides a service to lookup an existing JMS ConnectionFactory using the Java Naming and Directory Interface (JNDI).")
 @DynamicProperty(description="In order to perform a JNDI Lookup, an Initial Context must be established. When this is done, an Environment can be established for the context. Any dynamic/user-defined property that is added to this Controller Service will be added as an Environment configuration/variable to this Context.",
