Context: I am implementing JMS messaging, having a javax.jms.MessageListener implementing class (MDB) consume messages that are dispatched from a an ActiveMQ-provided JMS queue on an eexternal broker. In weblogic, this queue is configured as part of a 'JMS Foreign Server': A 'foreign' destination in WLS alongside a ‘foreign’ connection factory as part of a JMS Foreign Server definition which is (the only) part of a WLS JMS module. The foreign connection factory configured uses as 'JNDI Initial Context Factory' the 'org.apache.activemq.jndi.ActiveMQInitialContextFactory' and it uses as the JNDI Connection URL 'tcp://localhost:31313?trace=true', the adress of the broker. Furthermore the flag 'xa=true' is set on connection factory, because we're working in a Java EE container context.
Generally this JMS communication works, but because of some recurring acknowledgment issues i would need logging from the ActiveMQ *client* classes. On the broker logging is set up correctly already using the 'loggingBrokerPlugin'. My question is: How do i enable activemq-client's logging for activemq's components used in the Weblogic Foreign Server definition? Done so far: I have added the following classes to weblogic server instance's classpath, as required for JMS Foreign Server operation (see 'Reference' at bottom): - activemq-client-5.15.2.jar - hawtbuf-1.11.jar - slf4j-api-1.7.21.jar - jndi.properties (contains local <> remote JNDI mappings) I also added the following to weblogic server instance's classpath, as we are using log4j generally as logging backend. - slf4j-log4j12-1.7.21.jar - log4j-1.2.17.jar - log4j.properties (log4j config file) In log4j.properties I added this line and corresponding 'AMQ' (file) appender: log4j.logger.org.apache.activemq=debug, AMQ -> However, still no logfile is created for AMQ appender. Meanwhile in the server instance logfile by weblogic, I do see the JMS managed objects (connection factory, destinations) being constructed and registered in JNDI, and messages are consumed and acknowledged. But i haven't got the logging from ActiveMQ's own classes on the actual handling of messages thru the client. What am i missing or doing wrong? Is a log4j backend library (as i added in) required here? I hope someone can help me with some hints for this on the combo of ActiveMQ (5.15+) and WLS (12.1+). Thank you in advance, Patrick Reference: The following thread was important for us, for defining ActiveMQ-specific Foreign Server definition (instead of resource adapter) and registering ‘foreign’ queue and XA-transacted connection factory into local WLS instance’s JNDI for reference from MDB: https://community.oracle.com/thread/3903705 Following also has relevant principles for Weblogic as ActiveMQ client setup, but describes a JMS Bridge instead of JMS Foreign Server: https://fcosfc.wordpress.com/2015/06/11/setting-up-a-jms-bridge-between-weblogic-and-activemq/ -- Sent from: http://activemq.2283324.n4.nabble.com/ActiveMQ-User-f2341805.html
