Even if Class.forName would work correctly there would still be a problem. We need to seperate the loading of the log4j configuration into two phases to correspond to the two phases of loading the boot classes and then loading the remaining classes for the given server configuration.

If we can make a tiny and intelligent wrapper to use instead of URLClassLoader for ServerLoader, which will use the default URLClassLoader behavior until the UCL repository is up, then switches to using it... it might work, but I am not sure what the full implications of that would be. What we really need is a way to change the system classloader... so that code that uses Class.forName() will work correctly. But I expect that changes of that happening are close to nil... --jason On Tuesday 21 May 2002 11:16 pm, Scott M Stark wrote: > Inclusion of log4j.jar in the ServerLoader bootclasspath breaks > loading of unbundled classes used by appenders such as the JavaMail > classes since the DOMConfigurator used Class.forName to load appenders, > etc. Either the class loader created by the ServerLoader needs to be a > custom > subclass that dynamcically integrates with the UCL loader repository when > available, or we need to subclass org.apache.log4j.xml.DOMConfigurator and > override the parseXXX methods to use the TCL. > > log4j: Attaching appender named [ErrorNotifications] to appender named > [ASYNCH]. > log4j: Class name: [org.apache.log4j.net.SMTPAppender] > java.lang.NoClassDefFoundError: javax/mail/Multipart > at java.lang.Class.forName0(Native Method) > at java.lang.Class.forName(Class.java:115) > at > org.apache.log4j.xml.DOMConfigurator.parseAppender(DOMConfigurator.java:159 >) at > org.apache.log4j.xml.DOMConfigurator.findAppenderByReference(DOMConfigurato >r .java:144) > at > org.apache.log4j.xml.DOMConfigurator.parseAppender(DOMConfigurator.java:196 >) at > org.apache.log4j.xml.DOMConfigurator.findAppenderByReference(DOMConfigurato >r .java:144) > at > org.apache.log4j.xml.DOMConfigurator.parseChildrenOfCategoryElement(DOMConf >i gurator.java:361) > at > org.apache.log4j.xml.DOMConfigurator.parseRoot(DOMConfigurator.java:330) > at > org.apache.log4j.xml.DOMConfigurator.parse(DOMConfigurator.java:693) > at > org.apache.log4j.xml.DOMConfigurator.doConfigure(DOMConfigurator.java:593) > at > org.apache.log4j.xml.DOMConfigurator.doConfigure(DOMConfigurator.java:545) > at > org.apache.log4j.xml.DOMConfigurator.configure(DOMConfigurator.java:615) > at > org.jboss.logging.Log4jService$URLWatchTimerTask.reconfigure(Log4jService.j >a va:488) > at > org.jboss.logging.Log4jService$URLWatchTimerTask.run(Log4jService.jav > a:437) > at java.util.TimerThread.mainLoop(Timer.java:430) > at java.util.TimerThread.run(Timer.java:380) > > xxxxxxxxxxxxxxxxxxxxxxxx > Scott Stark > Chief Technology Officer > JBoss Group, LLC > xxxxxxxxxxxxxxxxxxxxxxxx > > > _______________________________________________________________ > > Don't miss the 2002 Sprint PCS Application Developer's Conference > August 25-28 in Las Vegas -- http://devcon.sprintpcs.com/adp/index.cfm > > _______________________________________________ > Jboss-development mailing list > [EMAIL PROTECTED] > https://lists.sourceforge.net/lists/listinfo/jboss-development _______________________________________________________________ Don't miss the 2002 Sprint PCS Application Developer's Conference August 25-28 in Las Vegas -- http://devcon.sprintpcs.com/adp/index.cfm _______________________________________________ Jboss-development mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-development _______________________________________________________________ Don't miss the 2002 Sprint PCS Application Developer's Conference August 25-28 in Las Vegas -- http://devcon.sprintpcs.com/adp/index.cfm _______________________________________________ Jboss-development mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-development
