This course gave me a very clear understanding about setting up Tomcat, deploying applications and setting the security. I learnt the JDBC aspect of the Tomcat and I really benefitted from this training as a developer


Instructor is excellent...

Mike - Prescription

The course was well put together. Some training courses don't plan out the Labs very well but this course did a great job of setting up clean well-defined labs that stayed on-point to the topic at hand. The instructor was extremely well prepared to teach the class as well as other parallel topics outside the scope of this course.

Brett - Walt Disney Animation Studios

Nothing to improve. Sasa was very knowledgeable and no question was outside his ability to answer solidly and consise. Very enjoyable.

LaJchon - SkillSoft

Outstanding instructor. Innovative, responsive and (best of all) took great care to point out all of the pitfalls, did not rely on simply presenting correct examples. Excellent presentation style, very clear and very consciencious at the same time.

David C - Computer Sciences Corporation

I like the pace. Very fast. Before this class I had not touched the Android build. I had only created a few small apps. I felt I was able to keep up because of the organization of the class.

Tom - Intermec Technologies Corp.

Sasa was very thorough and knowledgeable about the topics we discussed.

Griffin - T-Mobile
