Re: Help required on log4j implementation using WebSphere 4.0

[Tom Marsh]

John:

I'm sure there are a number of ways to do it, but we've been putting 
the .properties file in the same directory as the java class file 
(com.xxx.xxx.class) and using

InputStream is = getClass().getResourceAsStream("mylog.properties");

We're using this for servlets and EJBs.

This might bite you very hard in the future. It is a bad idea to
extend Logger to support new level types. You should use the
Logger.log method instead as in:

   logger.log(Your.custom.level, "your message");

The problem stems from the fact that the logger repository might be
set by the EJB Container and not your application. In that situation
the logger instances returned by Logger.getLogger might be
incompatible with what your application expects, i.e. you will get a
NoSuchMethodException when your application accesses info+() or
info-() methods.

Have you tested your Logger subclass properly?

Yes.  Just have 
seperate FileAppenders with different tolerance levels.  Check the FAQ on 
how to limit was an appender logs.
