Tipps for building a web application

Question

I have an idea for a web application. It is fun do do it and if well done, it can earn much money.
There are two people now working on it, inlcuding me. I develop the concept, write the servlets. He is good at XHTML.
What other skills does a typical web application need?
I think we need someone with law skills. If the application comes out, it may not contain any legal weaknesses. Otherwise competitors could destroy us easily. We would have no money to defend ourselves until the application earns money.
Of course we would also need someone who is good at business laws. A company has to be founded and so on.
How many people does a medium complex web application need? And what skill sets? What are important things to consider?

Answer 1

I'd say you need someone with A LOT experience and A LOT of knowledge in existing technologies (if youre doing e 90s style e-hype startup). And have an idea noone had before, because there is A LOT of existing solutions to almost any problem sold A LOT of times from A LOT of huge companies with A LOT of money.
I dont want to destroy you motivation but i think its gotta be more than 2 Quereinsteiger to earn money with j2ee on web. If it was i'd be riding a ferrarie and not doing student assistance at university or coding web apps for t-systems.
Still.. DO IT! 'Cause its really fun to learn the stuff and j2ee is a really nice framework. But go into details of j2ee and dont start coding servlets like you would 'code' html.
