- Core Java
- Java frameworks including, but not limited to, Spring and Hibernate
- Advanced Java such as J2EE, JSP, Servlets

In-person sessions are preferred, so facilitators who can deliver on-site training will be much appreciated. Prior experience in delivering Java-based tech training programs would be great.
