    I got this error when running cayenne-1.0.6 with
    commons-collections-3.0:
    java.lang.NoSuchMethodError:
    org.apache.commons.collections.IteratorUtils.singletonIterator(Ljava/
    lang/Object;)Ljava/util/Iterator;
             at
    org.objectstyle.cayenne.map.ObjAttribute.getDbPathIterator(ObjAttribute.
    java:140)

    One more thing about common collections: I am running
    jboss-3.2.1_tomcat-4.1.24 and that version of tomcat has a version of
    commons collections from before 3.0 that overrides the one in
    cayenne-1.1M4. I upgraded to 3.0 without any problems.
