Exclude stdout from certain Lib

[borobudur]

We are using alibrary which has some System.out.println("bla-bla") which we don't want to see on the console and in the log-file.

Is there a way how to exclude this libs output?

Lets say the lib is called org.mylib

I tried in jboss-log4j.xml with:

   <category name="org.mylib" additivity="false">
      <priority value="WARN"/>
     <appender-ref ref="CONSOLE"/>
   </category>

Try this:

  <category name="STDOUT" additivity="false">
       <priority value="WARN"/>
     <appender-ref  ref="CONSOLE"/>
   </category>

The category name is usually printed within braces, [...], in the JBoss AS log file and System.out text shows as:

2010-03-08 09:04:57,618 INFO  [STDOUT] (Thread-18) Retrieving document at ...

Better would be just to exclude this library but it's already a solution. Thanks!

Can I ask you an othere thing I'm trying to do but can't really find a good solution?

I would like to develop in debug mode but if I change to debug all the jboss debug output is shown too and the server is this slow that it doesn't really run anymore. How can I set the global to info mode and my application to debug? Thanks again!

You want your application's DEBUG level logs to appear on the CONSOLE? Or do you want them to be available in a log file?

Console

Try this:

<!-- Set the threshold of CONSOLE appender to DEBUG -->
<appender name="CONSOLE" class="org.apache.log4j.ConsoleAppender">
      ...
      <param name="Threshold" value="DEBUG"/>

      ...
   </appender>
   
   <!-- Set the log level of your app's loggers to DEBUG -->
   <category name="org.myapp">
       <priority value="DEBUG"/>
   </category>
   
   
   <!-- And set the log level of the root logger to INFO -->
   <root>
      
      <priority value="INFO"/>
      <appender-ref ref="CONSOLE"/>
      <appender-ref ref="FILE"/>
   </root>

That works, thanks!

I didn't find the concept of jboss/log4j threshold/appender to easy to understand. I made a little drawing. Perhaps it helps someone else.
