I am a beginner in J2EE technologies. I am a software engineer in a reputed firm. My project requirements limit me to work in only JSPs. I want to know how real time websites are implemented in J2EE?How do they handle millions of sessions everyday? How does the architecture affect the scalability and performance of the system.How exactly clustering is implemented? I dont think I will learn all these things by just reading some books. My project doesn't allow me to explore all these areas. So I thought if I get source code of some website like TSS, it could help me a lot in implementing a real time J2EE website.

Thanks in advance.....

Look on Sun's site for the "Pet Store" app.
