How to solve this problem?

Question

Hi there.
I've got a sample code, including some imports, and one of them is:
import org.apache.commons.collections.EnumerationUtils;but nowhere I can't find this class.
I've already downloaded jakarta-commons collentions , copied all the java files included, tried to compile them, but without any success :-(
I also tried to add manually files: EnumerationUtils.java , EnumerationIterator.java (EnumerationUtils imports something from EnumerationIterator) and then IteratorUtils.java, what is needed, but this IteratorUtils imports 20 other files and now I really don't know what to do...

Hmm... I did what you've told me. Downloaded this zip file, extracted commons-collections-3.2.jar somwhere and now:
PATH=d:\CFusionMX7\verity\k2\_nti40\bin;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOW
S\System32\Wbem;D:\java\jdk1.5.0_06\bin;C:\Program Files\Microsoft SQL Server\80
\Tools\Binn\;D:\Sun\commons-collections-3.2.jarBut when compiling the file, there's still a problem:
--------------------Configuration: <Default>--------------------
C:\Documents and Settings\doberman\Desktop\lekser\Lekser.java:5: package org.apache.commons.collections does not exist
import org.apache.commons.collections.EnumerationUtils;

                List list = EnumerationUtils.toList(stringTokenizer);
