Hi

I downloaded the last stable beta version. I installed ant. When compiling with ant I had 100 errors... It is errors cannot resolv symbol. I know how to program in java. but the cause is in the import that are not resonizer.ex

import com.sun.java.util.collection.Array;
are not found

WHen I program I import this class that way
import java.util.collection.Array;
My computer don't reconise com.sun
what can I do to don't need to change the import in the class?
Making an link form com.son to java? I didn't find where to put it
