Hello!
I want to write a Servlet basing on the velocity-template-engine.
Everything works fine, I have only difficultiies reading a XML file with SAX
and getting the sax-events into the velocity-context.
Could anyone give me a hint how to tell SAX to work with Velocity ?
My idea would be the following, but it does not work...
//*************************************
public class TestServlet extends VelocityServlet implements ContentHandler {
String testString;
protected Properties loadConfiguration(ServletConfig config )
throws IOException, FileNotFoundException {
//......
}
/*** SAX - Methods ***********************/
public void startDocument() throws SAXException {
// ......
}
public void startElement( String namespaceURI, String localName, String
qName, Attributes atts) throws SAXException {
// element "page" in my xml-file
if ( qName.equalsIgnoreCase( "page" )) {
// just a very simple event..
testString = "testString";
}
/*
... other possible Sax-Events
*/
public Template handleRequest( HttpServletRequest request,
HttpServletResponse response, Context ctx ) {
try {
String parserClass ="org.apache....."
TestServlet testServlet = new TestServlet();
XMLReader reader =
XMLReaderFactory.createXMLReader(parserClass);
reader.setContentHandler(testServlet);
reader.parse( "xml/test.xml");
} catch
// ..Exceptions ...
// -> THIS does not work, in the velocity-template I get for 'testString'
only $testString ...
ctx.put( "testString", testString);
//... end of velocity-servlet
/******************************/
I have no problems getting variables etc. into the velocity-context.
My problem here I think are the SAX-Events...
Thanks in advance !
Peter
