Log4j question

[Matt Givney]

Hi folks,
Great product, thanks for all your hard work!
Question about logging what the framework is doing when running an app on 
WebSphere. I have written and tested code using a simple datasource and 
running from my main method and I get the War & Peace style logging (love 
it!)

Though when I transfer the same code to a JSP, and switch my datasource from 
SIMPLE to JNDI, I don't get anything. Any ideas what I am doing wrong?

Here's a copy of my log4j properties file:
# Global logging configuration
log4j.rootLogger=DEBUG, stdout
# Console output...
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n
And here's the code from the JSP:
try
{
  SqlMapClient client = SQLMapConfig.getSqlMapInstance();
  List list = client.queryForList("getBrandCodes", null );
  if ( list.size() > 0 )
    System.out.println( "It worked!");
}catch( Exception exception ){
   exception.printStackTrace();
}
