[Opensource] Expresso installation problems with JBoss/Tomcat ?

[Ravishankar Bhat]

Further finding...

The error we are getting is 
	17:12:49,671 ERROR [STDERR] Expresso Configuration initializing...
	ERROR: invalid console appender config detected, console stream is looping
I have found out the following
1) The last ERROR message (Expresso Configuration initializing...) is coming from StdServlet.init() method
2) This method tries to set the ConfigManager and calls ConfigManager.config(ServletConfig) method
3) In above said method ConfigManager tries to call LogManager.setupLog()
4) At this time LogManager class is loaded and static variables are initialized
5) Since LogManager has the following static variable, we are getting the problem
    protected static Appender setupAppender = new ConsoleAppender(
                                                      new PatternLayout(),
                                                      ConsoleAppender.SYSTEM_OUT); 

I don't know how to solve the problem, but this is were we are getting the error.

Hope this helps,

Regards
Ravi

Hi All,
I wanted to find out more on this problem, but could not do much.
All I could find out are the following
1) There is a conflict of console appenders happening, when we use expresso with JBOSS
2) JBOSS has it's own console appender and adding any more console appenders will result into this problem
3) If we remove the console appender definition in expressoLogging will not solve this conflict. [So there is some class is adding the console appender directly]
4) There is only one class in expresso classes that uses ConsoleAppender of log4j and that is LogManager
5) LogManager creates this cosole appender as 
	setupAppender = new ConsoleAppender( new PatternLayout(), ConsoleAppender.SYSTEM_OUT);
	So it does not use any of the expressoLogging setups
6) LogManager has the following public method
    synchronized public static Category setupLog() {
        if (setupLog == null) {
            setupLog = Logger.getLogger("expresso.initialize");
            setupLog.setLevel(setupPriority);
            setupLog.addAppender(setupAppender);
        }

        return setupLog;
    } /* setupLog() */

7) Field Summary (JAVADOCS) of setupAppender fields states as follows,
	"Change this to get initial setup logging logged to a different location other than stdout." Author : Michael Rimov

I am sure, someone of you Expresso Gurus, can help me from here.

Looking forward for your help,

Thanks
Ravi

Maybe your snippet just didn't get pasted properly, but the 
"ConversionPattern" tag is not closed.
No other clues
