Hi,
I'm running Eclipse Java EE IDE for Web Developers build 20100917-0705 on a Mac and I'm getting an "80: method does not override a method from its superclass" error from an @Override of an interface. I've read that the 64 bit version runs 1.6 but this seems to be a 1.5 problem. FWIW I can do a command line build using ant build just fine so I do have 1.6 installed and running fine - how can I get Eclipse to use 1.6?
Thanks,
George

You don't have to use java 1.6 for it. You could just change the project compliance.

I do have the compliance set for 1.6 - there are no errors showing in editor or on package - no red spots. It's only when I compile using ant that I see the error. I can use ant from the command line though.

ant build from command line, click on build from Eclipse.

Rather than using ant I used javac to compile file that was causing error.

javac src/cs636/pizza/domain/PizzaSize.java -d bin/ -classpath lib/javax.persistence_2.0.1.v201006031150.jar

That came back with no errors.
