Thanks Alan, I modified log4j.properties under both conf/ and lib/, but 
starting Taverna still gives the same warnings.  As long as those warnings do 
not have significant meaning to me, I won't bother to disable them for now.


I attached the modified log4j.properties,
#log4j.rootLogger=WARN, CONSOLE

log4j.rootLogger=ERROR, CONSOLE
log4j.logger.net.sf.taverna.t2=ERROR

#log4j.logger.net.sf.taverna.t2=INFO
#log4j.logger.net.sf.taverna.t2.ui=DEBUG

#log4j.logger.org.apache.commons.httpclient=ERROR

# Default output to console
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%-5p %d{ISO8601} (%c:%L) - %m%n
