Adding new libraries in SmartFoxServer 2X is a breeze. No messing around with the classpath is required: all we need to do is deploy the .jar file(s) in the proper directory and restart the server.

There are two folders that we recommend to use:

{SFS2XRoot}/extensions/{the-extension-name}.
This is where we will typically deploy our main Extension .jar file. The jar file should contain only our Java code without the external dependencies, if any. The reason why the dependencies should be deployed separately is that if they are shared, they will be loaded once for all Extensions that use them.

{SFS2XRoot}/extensions/__lib__/
This folder is recommended for libraries that will be shared by multiple Extensions in your system. For example the “Google Collections” jar, or the Hibernate jar, etc. Do not add your Extension jar to this folder, because the AdminTool won’t ba able to detect it when you setup the Zone/Room configuration.
