Create translation web services in java?

  1. Create XML base with words?
  2. When a client requires a particular word in the translation, the service checks for the word in its XML-based If there is a word, service as an output to the client broadcast a translated word. If the word does not exist in the XML file, the service broadcasts adequate message. Because testing in an XML file you need to add a few words.
  3. Client benefits described service by calling the method translate, three string parameters. Example: translate(”butterfly”, ”english”, ”russian”);

SAXParser:

public class Main {

/**
 * @param args the command line arguments
 */
public static void main(String[] args) throws ParserConfigurationException, SAXException, IOException {
    SAXParserFactory spf = SAXParserFactory.newInstance();
    SAXParser sp = spf.newSAXParser();
    sp.parse ("words.xml", new MySaxHandler());
}
}

Handler:

class MySaxHandler extends DefaultHandler {
private String actualNodeName;

@Override
public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException {
    this.actualNodeName = qName;
}

@Override
public void characters(char[] ch, int start, int length) throws SAXException {
    if(!actualNodeName.equals("bs"))
        return;
    String nodeValue = new String(ch,start,length);

    if (!nodeValue.trim().equals(""))
        System.out.println (nodeValue);
}
}
