How can I enable for-each loop in Creator update 1?

I try to use for-each loop, but I got error message from compiler is

" for-each loops are not supported in -source 1.4. (try -source 1.5 to enable for-each loops)"

How can I switch my source to 1.5.. I am using jdk 1.5. Confusing.

Thanks .

Richard
