It really can't compare to ,Net for ease of use and power, but Ecipse was an attempt to give it a real visual IDE (failed unfortunately) and drag it into the 21C. Rather stupid of the Eclipse developers to use a name property, but I'm sure it seemed a good idea at the time - probably because there was no other solution available.
Java will be soon moving to the elephant's graveyard of programming languages.
