$(<Windchill>)/lib/servlet.jar
$(<Windchill>)/codebase/WEB-INF/lib/ieWeb.jar
$(<Windchill>)/codebase/WEB-INF/lib/ie3rdpartylibs.jar
where <Windchill> is the Info*Engine installation directory.
or
Extract the contents of $(<Windchill>)/ieconnector/ie.rar into a directory and add all JAR files found there to your CLASSPATH.
