We've installed eclipse and JRE (both 64 bit) on a 64 bit machine running WIndows Vista and are getting errors saying the claases like File, FileReader, and String cannot be resolved to a type.

Any guesses as to what is wrong?

Probably an incorrect runtime installation. Try making sure JAVA_HOME is set before starting Eclipse

Incorrect setup: more than one JRE is being used, i.e. one by the IDE and another by the compiler. Make sure you follow Eclipse installation instructions.
