My company is helping the post office upgrade its mail trackin system. The application was written using a PowerBuilder front end talking to an Oracle 8i database (on Win2000). Now, we are trying to decide if we want to use Delphi or Java as our new front end. Since I am not familiar with Delphi, can anybody gives me some suggestions? Performance wise (For me, performance means that the user clicks a button, and something happens quickly), which one responds to user quickly? In this project, we don't need to be multi-platform.
