[logback-dev] [JIRA] Commented: (LBCLASSIC-114) add a context listener that automatically configures JMX

[Paul Nyheim (JIRA)]

Paul Nyheim commented on LBCLASSIC-114:
---------------------------------------

The suggested implementation uses ServletContext.getContextPath, which was introduced in servlet-api 2.5 which makes it unusable on any J2EE 1.4 compatible app-server (such as WebSphere 6.1). 

While logback has a dependency on servlet-api 2.5, it is still compatible with servlet-api 2.4 AFAIK.

> Setting up logback JMX for a web application requires a bit too many manual steps. It is not enough to simply add <jmxConfigurator /> to the configuration file. You should also set the context path but often you can't know that in advance. In addition you still need to write custom code to [prevent memory leaks|http://logback.qos.ch/manual/jmxConfig.html#leak]. These issues could all be addressed by a custom context listener.
