Thanks for the advice. In the end, I loaded the logback config file
myself programmatically which allowed me to store and retrieve it from
where I wanted.
LoggerContext lc = (LoggerContext) LoggerFactory.getILoggerFactory();
try {
JoranConfigurator configurator = new JoranConfigurator();
configurator.setContext(lc);
// the context was probably already configured by default
configuration rules
lc.reset();
configurator.doConfigure(realPath + "/" +
this.getInitParameter("logback_filename"));
} catch (JoranException je) {
// StatusPrinter will handle this
}

There is no guarantee where the current working directory is set for a web

You can, however, ask the JVM where it got the byte code from for a given
class, by using http://www.exampledepot.com/egs/java.lang/ClassOrigin.html
// Get the location of this class
Class cls = this.getClass();
ProtectionDomain pDomain = cls.getProtectionDomain();
CodeSource cSource = pDomain.getCodeSource();
URL loc = cSource.getLocation(); // file:/c:/almanac14/examples/
(works for jar files too).
You can then make the information available to logback and refer to
${myvariable}/logback.properties.

Subject: Re: [logback-user] How to reference file one level above the web
context
Has anyone had to do this type of thing before? If I cannot use a
relative path, are there recommendations for an alternative approach?

I am trying to use the<property file="logback.properties" /> tag in
my logback.xml file to reference an external settings file. I want to
use a relative path and specify the file one level above my
application context. For example:
<web server root>/apps/myapplication/web-inf/classes/logback.xml
I want to put the logback.properties file at<web server root>/apps/.
Do you know what relative path I need to use to do this?
I've tried everything I can think of, including the following, but
they did not work:
<property file="../logback.properties" />
<property file="../../../logback.properties" />
<property file="/logback.properties" />
<property file="./logback.properties" />
Please help ... there has to be a way without using an absolute path!
