Thanks for info Scott. It helped. Okay so since I'm using ActiveMq 3.2.1 I put the geromino-jms-spec-1.1jar in my classpath and the activemq-core.jar in there too because another error was thrown saying that it wanted a class in that jar. Anyway,
I have chainsaw up with no errors (hooray) except for an "error creating log panel" error which I don't think is from what I'm doing because I get the same error if I just start chainsaw up normally without the config file. When I run my logging test program that sends log messages to the jms server I don't seem see anything happening in Chainsaw. I would have expected a new tab to pop up with the log events. My logging test program uses the JoranConfigurator to config log4j and then just loops sending out debug messages Here is the config file the JoranC reads: <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE log4j:configuration> <log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/"; debug="true"> <appender name="jmsAppender" class="org.apache.log4j.net.JMSAppender"> <param name="ProviderURL" value="tcp://localhost:61616"/> <param name="InitialContextFactoryName" value ="org.activemq.jndi.ActiveMQInitialContextFactory"/> <param name="topicBindingName" value="MyTopic"/> <param name="topicConnectionFactoryBindingName" value="ConnectionFactory"/> <param name="LocationInfo" value="false"/> <param name="Threshold" value="DEBUG"/> </appender> <appender name="console" class="org.apache.log4j.ConsoleAppender"> <param name="Threshold" value="DEBUG"/> <layout class="org.apache.log4j.SimpleLayout"/> </appender> <root> <level value="debug"/> <appender-ref ref="jmsAppender"/> <appender-ref ref="console"/> </root> </log4j:configuration> And when I start chainsaw I use this config file. <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE log4j:configuration SYSTEM "log4j.dtd"> <log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/"; debug="true"> <plugin name="jmsReceiver" class="org.apache.log4j.net.JMSReceiver"> <param name="JndiPath" value="C:\EngineeringTools\jars\ActiveMQ\activemq-3.2.1\conf\jndi.properties "/> <param name="topicName" value="MyTopic"/> <param name="userId" value="defaultUser"/> <param name="password" value="defaultPassword"/> <param name="topicFactoryName" value="ConnectionFactory"/> <param name="Threshold" value="DEBUG"/> </plugin> <appender name="console" class="org.apache.log4j.ConsoleAppender"> <param name="Threshold" value="DEBUG"/> <layout class="org.apache.log4j.SimpleLayout"/> </appender> <root> <level value="debug"/> <appender-ref ref="console"/> </root> </log4j:configuration> Note: the chainsaw config file has an appender in it because I have another program that also gets configured with this file and I thought perhaps with this other program I could config log4j with a receiver and then using the appender print the log messages received out to the console - I don't know if that would work or not but I wanted to give it a try. Anyway, sorry flood this mailing list but I'm desperate. I'd appreciate any help or insight into what I'm messing up on. Thanks again.
