Hi, Setup ESB 4.8.1 + MB 2.2.0 (3 Queues namely; UC7_QueueListnerProxy, javaVendor, otherVendor)
During a demonstration we were successfully able to define the rule set in-line [2] using a Rule Mediator. But when we try to upload the contents as messageRoutingRules.xml [4] file into registry and access rule set via Registry Lookup [1] we are getting a null pointer [3]. Where can we find a sample registry rule set xml file content? Please note that in ESB documentation [1] sample.xml file content is not provided.
