Jboss feedback as launching xtrans.ear,

What's this Log4j repositoryselector set to JNDIRepositorySelector?

A good example of log4j.properties file

#log4j.rootLogger = DEBUG, File
log4j.rootLogger = DEBUG, Console
#Console -- Console Appender
# Pattern: level, category, message
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
#Console -- layout for Console appender
# Pattern: level, category, message
log4j.appender.Console.layout=org.apache.log4j.PatternLayout
log4j.appender.Console.layout.conversionPattern=[%-5p]: %c.%M %m%n
#File--4 File Appender
log4j.appender.File=org.apache.log4j.FileAppender
log4j.appender.File.File=./log.out
log4j.appender.File.Append=false
#File -- layout for File appender
log4j.appender.File.layout=org.apache.log4j.PatternLayout
log4j.appender.File.layout.conversionPattern=%n%d{yyyy-MM-dd,HH:mm:ss,SSS} %-5p: %c.%M%m
log4j.appender.FIle.layout.TreadPrinting=true
log4j.appender.FIle.layout.ContextPrinting=false
log4j.appender.FIle.layout.CategoryPrefixing=false

Remove Servlet.class

During starting jboss and launching xtrans-EAR-0.1.3.ear, Jboss Application Server gave ERROR

[WebappClassLoader] validateJarFile(C:\java\jboss-4.0.5.GA\server\default\.\tmp\deploy\tmp25436xtrans-EAR-0.1.3.ear-contents\xtrans-web-exp.war\WEB-INF\lib\servlet.jar) - jar not loaded. See Servlet Spec 2.3, section 9.7.2. Offending class: javax/servlet/Servlet.class

The reason:
This indicates that the SERVLET.JAR file included within xtrans-web.war is unnecessary. This is because the file can be found elsewhere in the JAVA CLASSPATH.

So I just removed it from the /web-inf/lib directory, then error msg disappear.
