I tried adding a new custom module in Bahmni. I seem to be getting error whenever I try to call the services inside the new module from the existing Bahmni module. The new module has two child modules viz api and omod. I tried loading module(custom) through the admin panel, and I got following error.
HTTP Status 500 - Servlet.init() for servlet openmrs threw exception
