Mule Plugin Format
Mule instances can make use of Mule Plugins, which provide a way to extend the server behavior in an isolated way.
A Mule plugin is a 'zip' file with the following structure:
/ \- classes // plugin-specific expanded resources (e.g. logging configuration files, properties, etc |- lib // plugin-specific jars |- mule-plugin.properties // custom properties to be added to the registry instance used by the plugin (optional)
Mule Plugins must be placed in the folder

plugin.className- full qualified name of the class implementing the plugin
plugin.enabled- indicates if the plugin will be enabled/disable on Mule start
plugin.exported- list of classes, packages and resources visible to Mule Applications
loader.overrides- provides fine-grained control over class loading within a plugin.
