[midPoint] adding external jars

[Ashwill, Steven L]

Hello,
In the midpoint-4.8.3 build, how do I add an external jar file? 
Currently, in the 4.4.8 build, we just add it to the WEB-INF/lib folder in the war file and midpoint can access the methods in the jar.  What steps are needed to add a folder of additional jars. It appears that PropertiesLauncher might be the solution, but I want to check to see if it is supported by this build? Is it as simple as LOADER_PATH as an Environment variable and setting it to the path of the external jars folder?

Thanks,
Steve
