Course Testimonials
The course was great! However, the pace could have been slower. But I don't blame the instructor for this as the amount of material to cover was enormous... The Instructor was simply brilliant covering everything and some more in the given time.
Ideal course for a jumpstart to J2EE for experienced Java Developers... Marakana helped us get started on J2EE development in under 5 days!
Knowledge and experience and presentation skills were excellent.
Having had no prior knowledge of the J2EE spec, app servers, etc.; I found the course to be very enlightening.
An excellent course! And a pleasure to work with an instructor so well versed in the subject.
