Hi I tried to run (for a project) some class of this code on Eclipse. In particular i copied RegisterEnrollUser.java and all import that it needs ( CAClient.java - CAEnrollment.java - Config.java - Util.java - UserContext.java that i rename UserImpl.java and other class). Now i change caUrl with my IP address with :7054 port and i disabled the firewall of that port. Now if i run the code i get the following error and i don't know what can i do for fix it:
