+ <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 ([EMAIL PROTECTED]) for providing
this information. </p>
