This one is pretty easy.  Just put "phpsrvlt.jar" in the
$CATALINA_HOME/lib directory, and it will be made available automatically.
Alternatively, you can put it in the /WEB-INF/lib directory of your web
application itself.

The problem under Tomcat 4 is that the element ordering is not legal, so
the XML parser that reads web.xml rejects it.  To fix this, put all the
<servlet> declarations first, followed by all the <servlet-mapping>
declarations.

The most likely explanation is that you have a servlet.jar in your
$JAVA_HOME/jre/lib/ext directory.  This interferes with the servlet.jar
file that is included with Tomcat, and causes "xxxxx is not a Servlet"
type error messages.
