Hi, I created my own appender that logging data to another ejb using JNDI. My question is, how can I add my external jar package to log4j.xml, beause when I do this: | <appender name="xxxx" class="logg.to.MyClass "> | | <layout class="org.apache.log4j.PatternLayout"> | | <param name="ConversionPattern" value="%t %d %x %-5p [%c.%M] %m%n"/> | | </layout> | </appender> | | <category name="ptk.cv.scoring"> | <priority value="INFO" /> | <appender-ref ref="xxxx"/> | </category> | I get the error: ?Could not create an Appender. Reported error follows. java.lang.ClassNotFoundException: logg.to.MyClass? I added jar with my appender class in: jboss/server/default/lib I put this appender in to log4j.xml because I have to be able change logg level dynamicly through jmx-console. I?m using jboss-4.0.5.GA and sdk_1.4.2_13. Thanks for any help. Lidon. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4032741#...
