Last updated on MARCH 16, 2022

Applies to:

Oracle API Gateway - Version and later
Information in this document applies to any platform.


Oracle API Gateway (OAG), OAG integrated Active MQ.

After enabling OAG embedded Active MQ via
  Server Settings -> Messaging -> Embedded Active MQ -> check the Enable Embedded Active MQ Broker,
in the Messaging tab in OAG Manager, MQ is still shown as disabled: "MESSAGING IS DISABLED".

The following messages are observed in the Gateway's trace file:

[Embedded ActiveMQ Service] ERROR org.apache.cassandra.service.CassandraDaemon - Exception in thread Thread[Embedded ActiveMQ Service,5,main]
java.lang.NoSuchMethodError: org.slf4j.helpers.MessageFormatter.ArrayFormat(Ljava/lang/String;[Ljava/lang/Object;)Lorg/slf4j/helpers/FormattingTuple;
  at com.vordel.ama.AMALoggerFactory$AMATraceLogger.debug(
  at com.vordel.ama.AmaBrokerManager.start(
  at com.vordel.ama.AmaModule$



The problem shows up only if older SLF4J jars were added to the classpath.
