I very much interested to learn the J2EE but I am confused that in which type of project I can use J2EE technology. I have alreay worked with servlets & jdbc but now I want to do the programming for J2EE. If I could get any sample project for J2EE, it will help me a lot to understand the J2EE technology.
Katyayani, Servlets and JDBC are actually part of J2EE--so you've already been doing J2EE projects! You may want to pull up the J2EE website and look the various specifications that are under the J2EE umbrella. It's a big topic. I don't think there are many developers that will use all of J2EE all the time. Most likely, you'll deal with subsets. But, looking at the J2EE tutorial and documentation will give you a good idea of what sort of things you can do with J2EE and why it's even necessary.
