Hello Dawson, Contrary to spring for example, logback relative paths are relative to the current working directory and not relative to the referencing file. HTH, On 08/11/2010 3:37 PM, Dawson Mossman wrote:

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! Dawson

Thanks, so in my example below ... what would I need to use for the relative path?

Relative paths in logback follow the usual relative path conventions. For example, x.txt and ./x.txt designate the file x.txt located in the current working directory whereas .../x.txt designates the file x.txt located one directory above the current working directory, ../../x.txt designates -- well you get the idea.

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 } On 09/11/2010 4:45 AM, Thorbjørn Ravn Andersen wrote:

There is no guarantee where the current working directory is set for a web application (which is what a relative path works from).

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.

Has anyone had to do this type of thing before? If I cannot use a relative path, are there recommendations for an alternative approach?
