Using log4j and SMTPAppender

[sruch]

hi all,
has anybody configured an SMTPAppender successfully?
i always get an "java.lang.NoClassDefFoundError"-error when i try to start jboss...

TIA

hi ralph
didn't try it again... but perhaps with the newest version of jboss the error disappear... :-)

I just started using the SMTPAppender under JBoss 2.4.4 and have noticed that if I deploy my application using the SMTPAppender after JBoss has started everything works fine, but if I try to start the server with the app already deployed it fails. In looking at the log I see that Log4JService is the first service started and must be occuring before the mail.jar is loaded. I'm left to wonder if this is just a configuration issue, but I have no idea what to change. I'll play with things a little and see if I can figure something out.

I looked at the configuration and found that if I change the line in jboss.conf that starts the Log4JService from:

<!-- The log4j based logging service based on the conf log4j.properties file -->



to

<!-- The log4j based logging service based on the conf log4j.properties file -->
<MLET CODE = "org.jboss.logging.Log4jService" ARCHIVE="jboss.jar,mail.jar,activation.jar,log4j.jar" CODEBASE="../../lib/ext/">

My application deploys fine and appears to work as expected. Hopefully I have not broken anything further down the line with this change.

I hope this helps...
