j2ee versus .net development estimates

Question

This is not a request for opinions. Please only respond if you are 1) a strong j2ee/oracle developer 2) a strong .net/sql server developer, and 3) have developed nontrivial web apps in each framework.

My question is what is the relative development time for a given specification in each platform. Let's say for the sake of comparison that there is a 5 man, 3 month project in .NET, would it take more, less, or the same amount of time to develop in j2ee given j2ee developers of comparable skill?

thanks in advance - this is not a hypothetical question - we have to reestimate a .NET project in j2ee...

Answer 1

Given developers of equal talent in each respective platform, I'd say that development would take about the same amount of time. There are some things that each platform does better, but without further information, I'd say it's about the same.

Answer 2

In general, the amount of time needed to complete a project does neither depend on the technology used nor can it simply be calculated by the teams size. The main factor for a projects time are the developers: their skills, their motivation and their individuality. Some people are very effective in plain C. Others never get things done in JEE, although it only requires a fraction of code lines.

Answers to this question sonly can be subjective.
