Java EE (Java Enterprise Edition) General Discussion

Ok i'm sure this should be an FAQ but I'v googled it and got nowhere. I'm probably being really blind.

But: I'm trying to use the Xerces parser in my program, and I am importing the following:

import org.apache.xerces.parsers.SAXParser;

for use in the following method:

        public void process(Session session) throws IOException, SAXException {
                // Create a Xerces SAXParser

                SAXParser parser = new SAXParser();
                // Content handler

                parser.setContentHandler(this);
                parser.setReaderFactory(new StreamingCharFactory());

                // save the session
                this.session = session;

                // Start the parsing..
                parser.parse(new InputSource(session.getReader()));
        }

Yet, my IDE is telling underlining the "org.apache" of the import and complaining that it cannot be resolved. I understand that I have to import the parser, ie the xml-apis.jar and xercesImpl.jar, yet where do I put them?? :s Any help to de-confuse me would be very much appreciated! :)
