<div class="note"><span class="notetitle">Note:</span> IBM Toolbox
for Java provides
a second set of classes, called the <a href="resources.htm#resources">resource
classes</a>, for working with iSeries objects and lists. The resource
classes present a generic framework and consistent programming interface for
working with various iSeries objects and lists. After reading about the
classes in the <a href="javadoc/com/ibm/as400/access/package-summary.html#NAVBAR_TOP">access package</a> and the <a href="javadoc/com/ibm/as400/resource/package-summary.html#NAVBAR_TOP">resource package</a>, you can choose the object that works
