Look at log4j.properties to see how to configure. If you want details, view
the documentation or download log4j at
http://jakarta.apache.org/log4j/docs/index.html. Note that log4j can also
be used for standalone programs. Once you configure, where the results
show up depend on how you configure. The two most common options are
console and file. You can specify where the log files are placed. The link
above provides some sample programs. Here is a quick snippet from an EJB I
wrote:
private final Category log = Category.getInstance(getClass().getName());
public void ejbCreate() throws RemoteException, CreateException
{
if (log.isInfoEnabled())
log.info("ejbCreate() called");
}
If you read the docs, you don't need the isXXXXEnabled() call - log4j will
filter, but it saves some CPU cycles.
