Q.) Which Design Patterns are mostly used in J2EE Projects?

[vishnu_vaka]

That varies from project to project , more commonly in web applications we use MVC (struts, jsf,springMvC, web work all are MVC variants ) in WEB layer and in DAO at Database layer , VO to transfer objects across the layer layers, Business Deligate and Facade to communicate with different layers .

Hi radhika,

There are so many design patterns which we used in a J2EE project, depending on our requirement we will be using them
Please refer the following link : Core J2EE Patterns: J2EE Patterns, Refactorings, Best Practices and Design Strategies

Let me know your questions

Thank You

The DAO pattern is not what I'm talking about, that is the way business
logic delegates the details of the data storage to the DAO. I'm
refering to what actually goes on inside the DAO. Many people who are
used to dealing with Entity Beans, treat Hibernate components exactly
the same way and there are major differences in the way the respective
entities need to be managed.
