Roma is an Open Source initiative to make Java application development easy. The approach is totally DDD: let's think to the domain of your application and Roma will make the rest: persistence (database), presentation (HTML + Ajax), logging, user ... [More] management, sessions, workflow, scheduler, etc. Roma is a Meta Framework namely a tool that aims to remove dependencies between your application code and frameworks and tools you use. This allows you to change the technology at zero cost without any changes to your application code. Roma is also a MDA implementation since takes its concepts and philosophy but it's totally based on POJOs without to learn other micro languages and complex standards. [Less]

easy ORM (Object Relational Mapping)We had to change the name of this project because of one of the already existing more matured project which is also called "Simple ORM"Recently there have been lots of hype about dynamic languages and frameworks ... [More] like Ruby on Rails. Many have blogged about pros and cons of RoR and such dynamic languages. The hype is so high that it made me learn (J)RoR. After some reading and some projects on RoR I learned that programmers love these languages because of its ease of use and I loved it too. Many also say that these kind of languages are "threat" to Java, after all Java is complex!! For a Java developer it is a hard thing to just start working in a whole different environment and start using whole different syntax because no-one likes learning curves. Finally I thought that isn't it possible to get this kind of ease of use and simplicity in Java, Java is a powerful language, isn't it? This is an API which is easier then usual JDBC way of retrieving and storing data, it is easier then Java persistence and and compatible with all the JDK versions. The project is created one goal, SIMPLICITY. A simple ORM model which can substantially reduce code re-writing and is built on simple java concept of inheritance, it should involve no Rocket science. This API is right now only getting tested in MySql Follow the link bellow for more detailed explanation of SORM http://sites.google.com/a/cynosuredev.com/simple-orm/Home/Documentation If you have any questions or suggestions please feel free to email me at sapanparikh18 at gmail dot com --sapan [Less]
