The error shown in your message looks to be due only to the ap not being deployed properly, or not running at the time you made your request. OWLAPI itself wouldn't interact with the application server at that point. For issues like these, please use https://github.com/owlcs/owlapi/issues
Hi, you can download the OWL API from the Files section https://sourceforge.net/projects/owlapi/files/OWL%20API%20%28for%20OWL%202.0%29/...
