Tomcat Logging level change
Hi,
I am changing the log level of tomcat to Level.WARNING. In this case I'm
trying to restart tomcat and see the logs, I can see the info level logs
like "INFO: Server startup in 50516 ms" .
I guess info level logs should not appear if log level set to warning.
Kindly let me know how exactly it behvaes and why am i getting info level
logs?

Did you read the documentation? The file itself is documented, somewhat,
also.
Remember that each logger can be configured differently. So, if you
configure one logger to be level=WARN, other loggers may default to
something else.

I would do this at the configuration-file level. As Konstantin points
out, webapps aren't allowed to change the logging configuration for the
server. That would be a security problem, don't you think?

Do i need to make any chnages in the logging.properties file?
I tried making everything from FINE to WARNING and also i tried adding
org.apache.catalina.level=WARNING in the logging.properties, it somehow
worked. But Is this the way it should behave or we need to make changes in
my java code as well using that LogManager etc. Could you help me?

You know, 6.0.32 is out there...

It won't work, because the LogManager implementation used by Tomcat
(see docs for details) provides isolation for different webapps (class
loaders).
You code will affect only single webapp, and will have zero effect on
anything else.

(This is like pulling teeth.) You're providing virtually no useful information here. You run the program where? As a servlet? Standalone? In some listener inside Tomcat?
If you run it outside of Tomcat, why do you think it would have any effect on what's going on inside Tomcat?

Tomcat version is 6.0.9.
Here is my snippet of code:
LogManager logManager = LogManager.getLogManager();
Enumeration<String> e = logManager.getLoggerNames();
while (e.hasMoreElements())
{
String loggername = e.nextElement();
Logger logger = logManager.getLogger(loggername);
Handler[] handlers = logger.getHandlers();
if (handlers != null && handlers.length != 0)
{
for (Handler h : handlers)
{
h.setLevel(Level.WARNING);
}
logger.setLevel(Level.WARNING);
}
}

1. If you did it correctly then yes, they should not appear. But what
exactly did you? Please be specific.
2. Exact Tomcat version, etc.

The sources are all available.
java.util.logging documentation is available from Oracle.
