 The python wrapper uses the [[https://pypi.org/project/JPype1/|JPype]] library to directly interface with the Java code.
+For the tool,copy the GEMToolRuntime.jar from the TransSECS GEMTool project into the build folder
 For the host,copy the GEMHostRuntime.jar from the TransSECS GEMHost project into the build folder
