<faq title="ClassCastException using Xerces">
- <q>Why do I get ClassCastException when I use Xerces and WebSphere Application
Server (WAS)?
- </q>

-Xerces uses the <code>ObjectFactory</code> class to load some classes dynamically,
e.g. the parser configuration. The <code>ObjectFactory</code> finds the specified
implementation class by querying the system property, reading
<code>META-INF/services/factoryId</code> file or using a fallback classname. After the
implementation is found, the <code>ObjectFactory</code> tries to load the file using
the context classloader and if it is null, the <code>ObjectFactory</code> uses the
system classloader.

-<p>
-If you run Xerces in an environment, such as WAS, that has multiple classloaders
you may get ClassCastExceptions thrown from Xerces because different classloaders
might get involved in loading Xerces classes. For example, ClassCastExceptions may
occur when utility EAR classes that use Xerces load Xerces classes from WAR modules.
