time estimate for jdbc work?

I was curious what people here thought about a time estimate for this jdbc project? With these issues - how long would the project take? (A guy I know in Seattle has this same project.)

Create a web based application using Oracle, hibernate, struts, jsp, servlets, logging, jndi. Input is two systems. One system is used to authenticate login. The other is a database that is for a shopping cart - browse cart items, update cart items, delete cart items, and change cart items. The entire system must be secure and run on WebSphere Server. The data is in a database that has four tables - and this will require several inner & outer SQL joins across the tables. The GUI needs to be user friendly and include help files.

If one guy worked on it - how long would it take? Nothing is done yet. Create written use cases, create UML, create all design & all code - with no existing models or work to start from.

My rough estimate was 3-4 months(which is 480 - 640 hours).

???

thanks,
Keith

Keith,
It depends. The answer could vary widely based on how much experince the person doing the work has and if they have done this kind of thing before. It also depends on whether the environment was ready. Also, it would depend on how much of the (detailed) requirements were known in advance - subject to change.

thanks for your response. Here is more info.

YES - the guy has experience doing this - but is new to Hibernate & struts.

YES - the environment is ready.

YES - the requirements are completed and are in writing.

Do you think my estimate 2-3 months is valid?

thanks,
Keith

Keith,
I've never used Hibernate, but I think the rest of it is doable in 3-4 months (your initial estimate.) It's nice that the requirements are frozen and in writing. That should make things easier.

OK!

This is all very interesting. I was curious what people here had to say about reasonable time estimates. My own personal opinion was 3-4 months.

But actually, I had a piece of information that I withheld => What happened is that he was given 3-4 days to do it - and when he couldn't get it done in 3-4 days he was fired.

Life is very harsh for Java developers these days.
