HELP Application Server PE 9 - DocumentBuilderFactoryImpl not found

i getting this error in a Servlet. The same code work fine in a stand-alone local application written in NetBeans IDE... see the code :

try{

src.getDocumentElement().normalize();

NodeList listOfJDBC = src.getDocumentElement().getElementsByTagName("query-string");

int totalJDBC = listOfJDBC.getLength();

results:

org.apache.xerces.jaxp.DocumentBuilderFactoryImpl not found

Do i have to load this library in the application ? ... in the stand-alone app i don磘 use any diferent library than the jdk 1.5 ... and works...

any one can help... this code read a xml file with the tag node <query-string>...

thank磗.. max.
