Java Development Tools

Hi
I get error from xmlparserv2 in next example:

package client;

import java.io.File;
import java.io.FileInputStream;
import oracle.xml.parser.v2.DOMParser;


public class handingXML {
private static File fl_ini = new File("handlingXML.xml");


public handingXML() {

super();
}

public static void ini_t(){

DOMParser parser=new DOMParser();

try {

FileInputStream fis = new FileInputStream("C:\\JDeveloper\\mywork\\Application_XML_1\\Client\\handlingXML.xml");
parser.parse(fis);


}
catch (Exception pc) {
pc.printStackTrace();
}
}


public static void main(String[] args) {
ini_t();
}

}


The error stack looks like this
