This topic is designed for those still learning to develop web apps with Java or wanting to learn how to use a new framework.

If we were reading a book that taught any technical subject, and it didn't have examples, which would be our performance after reading it? We would have a theoretical knowledge, full of doubt, insecurity, uncertainty and other adjectives we could use to define this scenario. It is not good to learn many things without seeing examples or theory working in practice. Hence the motivation to learn by reading and seeing theoretical documentation and examples is very important for those who want to earn more knowledge in a specific subject related to software development.

If you don't know yet how to create a web application, J2EE Spider is a great tool to help you in your discoveries. You can create parts of a project and go step by step seeing examples on how to use each feature and resource you  learned when reading a book or surfing the web. After learning you'll be familiar with the technology and the tool will increase your productivity and help you on a daily basis.
