I've been presented with a long-term project opportunity that demands the following:
a. Oracle database
b. Java JDK 1.5
c. Web Logic as the web server
d. Spring and Hibernate frameworks

Has anyone here used these before? I've coded Java before but not using these components. I've looked at them a bit and they seem fairly involved. I'm imagining (perhaps naively) that I could get up to speed on this in the 2-3 month interval before the project would begin.

Mostly, I'm wondering:
1) Is it possible to set up a development server using free (as in no money) downloads or does one have to pay license fees? I found a link to JDeveloper (which is apparently free) here but I don't really know how much development one can do without an actual server to run things on.

2) How much does it cost to set up a development server with the aformentioned parameters? The oracle software all looks pretty pricy and I can't help but wonder if they have free versions that are not for production use.

3) How much does a production server setup cost? I don't foresee traffic for this project exceeding the capabilities of a single machine but I don't even know which pieces of software I would need to buy. If it's really pricey, I might try to talk them into a LAMP stack.

Lastly, any anecdotal wisdom about this would be much appreciated--especially info about getting up to speed coding with it. The project I'm looking at is fairly small, but has e-commerce components which could prove tricky for a noob.
