  +    <faq title="Servlet unable to find classes for extension functions/elements">
  +    <q>My servlet cannot find classes that implement extension functions or elements.
What can I do?</q>
  +    <a>
  +    <p>If you install xalan.jar in the servlet engine's lib directory (e.g., tomcat/lib),
as opposed to the servlet's 
  +    lib directory, then the Xalan classes are loaded by a classloader that does not see
the classes in the servlet's
  +    classloader (i.e., the extension classes, if you placed them there). The Xalan classes
try to load the extension 
  +    classes using their own classloader, and that attempt fails.</p>
  +    <p>Workaround: place xalan.jar in the servlet's lib directory and NOT in the
servlet engine's lib directory. 
  +    Another workaround is to place the extension classes also in the servlet engine's lib
directory, but you
  +    generally want to avoid cluttering that directory.</p>
  +    <p>Thanks to Gunnlauger Thor Briem (gthb@dimon.is) for providing this information.
