Java EE Server Technology
When Java came up in the 1990ies I was very happy to leave C++ behind me and I have preferred Java Implementations wherever possible. The Java Platform, Enterprise Edition (Java EE or JEE) increases developer productivity and meets enterprise demands.
Please check out the JEE White Paper to get the picture.
And as JEE is widely accepted and Java was just awarded 'Programming Language of the Year 2015' (TIOBE Index) there are endless Third Party Modules that fit seemless to any JEE Application.
The Process is Community driven and you can rely on stability of the complete Development Lifecycle. Development, Testing and Deployment have become so mature that the complete Lifecycle can be automated with Tools like Maven, JUnit, Arquillian, Jenkins (Continuous Integration and Release) and many more (to come).
If I can create a JEE Module for you it will be delivered with its own Maven pom.xml file for Building and Testing the Module in the dedicated environment. The Module should be easy to integrate in your development and release chain.
