[logback-user] auto context name creation

Hi, i switched to logback because it sounds promising. I have an web appplication (Tomcat6) which can be deployed more than once. In the FAQ i've read this to get a context-based logging. <env-entry> <description>JNDI logging context for this app</description> <env-entry-name>logback/context-name</env-entry-name> <env-entry-type>java.lang.String</env-entry-type> <env-entry-value>ContextApp-A</env-entry-value> </env-entry> Is it possible to auto-create a different "ContextApp-A" value? Reason: I want to deploy nearly the same WAR under different names at the same time. Example: myApp22012008.war and myApp23012008.war Cheers, Ingo
