title: jboss as 5.1 logback slf4j log4j
body: <p>I am using logback in a webapp on jboss 5.1. The webapp is using slf4j API. The output, though, looks like a combination of log4j and logback. The log4j message appears to be the logback output. Hence, tow timestamps, INFO and DEBUG, etc.</p>
  
  <p>2011-02-02 09:34:05,359 INFO  [STDOUT] (http-127.0.0.1-8080-2) 09:34:05.359 [http-127.0.0.1-8080-2] DEBUG com.clear.wib.servlet.Proxy - wib data available = 1783 </p>
  
  <p>How can I get the webapp to only output the logback message? Thanks!</p>
