The concept of drop-in JARs is supported by IoC Utils, even if the underlying IoC framework does not support it. This is the case with the default implementation framework, Google Guice, at the time of this writing.
A JAR bundled with the services implementations and interface will be picked-up by IoC Utils at startup time and the services will be passed to the underlying IoC framework upon it's initialization. More details on this topic can be found in the new implementation section. There is shown how these pluggable modules are found and passed to the IoC initializer.
