About the Platform
Marakana Tomcat Training course can be taught on both Windows and UNIX/Linux-type environments. The instructor covers both options during the training.
Marakana.com Runs on Tomcat
Marakana.com is written in Java using Spring and Hibernate frameworks. We deploy it on Apache Tomcat Application Server. Both Marakana Spark and Apache Tomcat are Java applications and thus run on Java Virtual Machine. Spark uses MySQL database for persistence. Our operating system of choice is Ubuntu Linux, for security and reliability reasons. So we practice what we teach. You will learn from real developers.
Trademarks
Apache™ and Tomcat™ are a trademark of The Apache Software Foundation. All other marks are the properties of their respective owners.
Java Meetup Organized by Marakana
Marakana team organizes and runs the San Francisco Java Meetup - an interactive group of Java developers. In our monthly meetings, we discuss Java landscape from both technology and business angles.

This is THE course to take if you need to know more about Tomcat and THE guy to teach this course is Sasa. Awesome guy, well versed and knows his stuff inside and out. Very productive and well learned base to do more with Apache/TC. Thanks Marakana and Sasa for the great time in San Francisco. OH - ask to see the dog... she's the best...
Very patient, great instructor, really knowledgeable. 'Excellent' really aplies to [the instructor]!
The course content was very useful. The material was very well structured and presentation was excellent. The instructor was very knowledgeable. Overall, this is probably the best course I have taken.

One of the best classes I have ever had. I will definitely be looking to come back again!
It was definitely a very good learning experience.
Excellent Training!
Nothing to improve. The instructor was very knowledgeable and no question was outside his ability to answer solidly and concise. Very enjoyable.
This class is like participating in a Vulcan mind meld. It is a wealth of information that you can take with you. Highly recommended!
I would highly recommend this class for any one trying to obtain tomcat skill or understand overall Middle ware application server skills. The snippets of development were helpful to understand the overall technology and how it all works together.
Awesome experience. Best training course I've ever attended.
Marakana offered us a comprehensive and knowledgeable view of Tomcat that prepared us to meet the challenges of converting our entire Application Server infrastructure to the low-cost open source solution offered by Tomcat.
This was an excellent course, I was able to put all the TOMCAT bits and pieces together. Will be better able to tune/configure TOMCAT. Thanks Marakana.
Loved the class, great experience!
We may invite the instructor come to our company and teach us.
Loved it! Great info... great instructor!
The instructor was great, well-rounded instructor, has expertise in the Tomcat and Java. This is definitely one of the best technical training course I have taken! I'd recommend this class to other Systems Admin who wants to learn more on Tomcat!
Sasa was an excellent teacher.
This was a very thorough class. I learned much more than I ever expected. Instructor knew the material inside and out and was able to answer all questions completely. The diagram of the server layout alone was worth whatever the class cost is.
The instructor has an excellent amount of knowledge. I wish I had more time to take additional classes and ask questions for fulfilling my expertise in other disciplines like apache, java, mysql, etc.
Instructor is well informed with the ideal set on figuring out things for yourself and if you really get stuck he can easily help you out in more detail.
The instructor took time out to help me address some issues that we have been having on a new Tomcat implementation, so major Kudos to the instructor.
The breath and depth of the instructor's experience and knowlege was phenominal. The course was a great experience.
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
