Subject [jira] [Commented] (AMQ-3764) JMSAppender cannot connect to activemq using failover
Date Thu, 07 Jun 2012 07:34:23 GMT

Rodrigue Bouleau commented on AMQ-3764:
---------------------------------------

I have the same issue when I want to use the JMSAppender with the failover option.

I create a small eclipse project (see attachment) with these files:
- Log4jJMSAppenderExample.java
- log4j.xml
- log4j-jms.properties
- jndi.properties
- every jars found in ActiveMQ _lib_ directory
- log4j-1.2.16.jar found in ActiveMQ _lib/optional_ directory
- slf4j-log4j12-1.6.4.jar found in ActiveMQ _lib/optional_ directory

In debug mode, I suspend the two Threads (main & ActiveMQ Task-1).
The main thread is blocked in FailoverTransport ({{FailoverTransport.oneway:524}}).
The ActiveMQ Task-1 is blocked in the TcpTransportFactory during the instantiation of the
Logger ({{Log4jLoggerFactory.getLogger:58}})

{panel:title=Output without failover option|borderStyle=none}
{noformat}

If I remove the jar *slf4j-log4j12-1.6.4.jar* from the classpath, everything works fine and
see the output below:

{panel:title=Output with failover option and without slf4j-log4j12-1.2.6.4|borderStyle=none}
