Problems with JDom

Question

In my Jdom program I got the following errors during compilation. It could compile on one machine,
but it did not on another,even though I made sure the machines are set up properly:
package com.sun.java.util.collections does not exist
import com.sun.java.util.collections.*;
^
file com\sun\java\util\collections\List.class not found
outputter.output(jdomDocument, new FileOutputStream(outputfilename));
^
2 errors
Same thing with running it. I could run it on one machine, but not another:
Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/java/util/collections/Collection
at org.jdom.input.DefaultJDOMFactory.document(DefaultJDOMFactory.java)

I've a similar problem. With this code:
import org.jdom.*; // version 8 beta
import org.jdom.input.*;
public static void listChildren(org.jdom.Element current) {
java.util.List children = current.getChildren();
Iterator iterator = children.iterator();
while (iterator.hasNext()) {
Element child = (Element) iterator.next();
listChildren(child);
compiled on NetBeans 3.4, I've got this error:
incompatible types:
found : com.sun.java.util.collections.Iterator
required: java.util.Iterator
Iterator iterator = children.iterator();
????????
