Framework chosen

Nowadays, many IT organizations have applied different combinations of Java technologies to write new applications in and migrating existing applications in Java environment. However, one major aspect of Java is its enormous variety and breadth. There is no one way to create a system. In fact, there are many options we can choose between probably hundreds of combinations of Java technologies in JEE environment: JSP, Servlet, Spring Framework, JSF, Oracle ADF, Tapestry, etc. Nobody can state exactly which one is the best for the application development. I would like to state that vendors like Oracle (Oracle ADF technologies) and SpringSource (Spring Framework) create Java EE–compliant products by implementing the Java EE specifications.

Java Enterprise Edition (Java EE) is a set of standards and specifications (called a platform) that defines the environment for running software written using the Java language. Java EE (formerly called "J2EE") is created and maintained by Sun Microsystems, but anyone may suggest and work on enhancements using the Java Community Process.
