Someone else might need to answer about log4j.
For Resin's configuration, there was a bug/confusion introduced in
3.0.21. You'll probably need to have two separate configuration
items: a <log> and a <logger>. The <log> is equivalent to a
java.util.logging.Handler. The logger is equivalent to
java.util.logging.Logger. With 3.0.21, the level doesn't
automatically configure the logger's level (this is a mistake.)
So you might need something like:
<resin xmlns="...">
<log name="" level="finer" path="log/debug.log" timestamp="[%H:%M:%
S.%s] "/>
<logger name="" level="info"/>
<logger name="com.foo.mypackage" level="finer"/>
You can have different logging levels in each web-app. Just add the
<logger> with the appropriate level in each one.
<web-app xmlns="...">
<logger name="com.foo.mypackage" level="finer"/>
...
<web-app xmlns="..."
<logger name="com.foo.otherpackage" level="finest"/>
(The whole environment/logging level is tricky internally, so if you
don't see appropriate behavior when setting the level in a resin-
web.xml it is possible there would be a Resin bug.)
You can test the logging with the following jsp
test.jsp
<%@ page import="java.util.logging.*" %>
<%
Logger log = Logger.getLogger("com.foo.mypackage.Test");
log.info("info-level test");
log.fine("fine-level test");
log.warning("warning-level test");
%>
