jdk1.5.0_01 + eclipse3.0.1 problem using enum?

the environment I'm using is jdk1.50._01 + eclipse3.0.1.

When I try to type the class in eclipse, the keyword "enum" high-light and show error messages below:

- Syntax error, insert ";" to complete FieldDeclaration

- enum cannot be resolved( or is not a valid type) for the field Test.Action

- Syntax error on token ",", delete this token.

public class Test

{

enum Action {refresh, reTurn, forward, success}

public static void main(String args[ ])

{

System.out.println(Action.refresh);

}

}

I can compile the class successful if i straight compile at JDK.

But why the eclipse can't make it(can't compile automatically)?

Thanks.
