which framework is best for me?

i have completed scjp,scwcd certification. now i want to learn framework, which is best framework for me to develop web applications ?

I'm not sure about what you mean by this

"Best" in what way?

i am sun certified web component developer and i am very comfortable in developing web applications using servlet and jsp custom tags. now i want to learn framework which is used for developing web applications, but there are spring,jsf, struts etc ,among these and other frameworks which framework will be more suitable for me for developing web applications as i am sun certified web component developer? and i dont have any idea about EJBs.

Why don't you try all those frameworks and see which one is more suitable for you? There is no such a thing as best framework.

As far as i know Freddy Wong is right.
Everything has it own importance
For eg : Struts is useful in handling larger web-applications..
It also separates the business logic from view(the html part)
Now here we can apply Spring framework for bussiness logic and JSP/JSF/Velocity for View part.

thanks Anneshwar! i am planing to learn jsf framework.can you tell me what are the prerequisites for learning jsf framework.and shoud i know about struts framework before go for jsf framework?

JSF has nothing to do with Struts; they *can* be used together but are *completely* different things. You don't need to know anything about Struts to learn JSF.

thanks David! can you tell me the best book for jsf?

Not really; I know almost nothing about JSF.

JSF is a component-based framework whereas Struts is an action-based framework. These are two different beasts.

Choice of framework should be driven by your need.

I was also very confused with so many Java frameworks available. But the more you hear about frameworks, you have more confusion. If you are student and you have free time for testing and experiment, try to run some simple hello world app in each framework. To Java frameworks with similar functionality, some are popular than others [popular means the framework have many users]. Using popular frameworks, you have greater chance to receive supports from frameworks communities and may be easy to find a job with skills you gain during using frameworks.

From my experience, those following are popular:
- For bean management: Spring, de-factor standard
- For ORM: Hibernate
- For MVC: Webwork+Velocity (now Strut2), SpringMVC. I think webwork+velocity is the best combination. It is so simple to have a view with Velocity template.

For modular design: It is very important for you as a architect from the beginning seriously think of modular design. It helps to reduce complexity of your application, leverage concurrent development.
- maven module: maven also supports modular design but I feel this is so complex.
- osgi approach: according to what documented in osgi website and forum, I think this is worth a try. Publishing a module in osgi is no more than just registering an osgi service.

thanks David! can you tell me the best book for jsf?

You can ask at the JSF forum.
