There are three types Java based applications.
1. Stand alone application: Where the application can be run on the machine where the code is available and the application is required on minimum one main method. Developed using J2SE API
Code has to be distributed to get the output
Eg: MSOffice
2. Web Application: Where the application is residing on some container and can be access from any where either from intranet or internet depends on the container exposed and cab developed using J2SE and J2EE
Eg: Any internet based applications like Facebook
Technology: Servlets and JSPs
Framework: Struts and Spring MVC
Architecture: MVC
Requirement: Webserver which has Servlet container and JSP Container
ie WebContainer = Servlet Container + JSP Container
Limitations: Supports only HTTP based requests
3. Enterpise Application: These are superset of Webapplications and with additional functionalities like more sophisticated for Business logic where applications needed more transactions ( DB interations) and security.
Technology: Servlets, JSP and EJBs
Frame Work: Any Frame work including Struts and Spring
Architecture: MVC-n tire
Requirement: EJB Container along with WebContainer
Advantages:
1. Protocol Independent
2. Fully Distributed
3. Full fledged business logic can be implemented with out any other frame works or tools like ORM
