JSR 172 XML parser in WTK 2.5: problems compared to 2.2

Question

Hi,
I'm experiencing 2 problems with the WTK 2.5 JSR 172 XML parser that do not occur with:
-WTK 2.2
-Sony-Ericsson Emulator WTK2
-Sony-Ericsson devices.
They are:
- attributes.getLocalName(i) always returns an empty string
- documents with multiple roots cause a parser panic
Anyone has a hunch?
Thanks a lot,
Philippe

Answer 1

I wonder if anyone has encountered the same problem as I and has found a workaround about it. I am trying to create a UI builder that generates itself by reading an XML file.
One of the elements is a Combo Box, which should be read from the following structure:
<form>
          <combobox>
                   <value>My first value</value>
                   <value>My second value</value>
                   <value>My third value </value>
          </combobox>
</form>Then I proceed to generate a vector of UI Elements, and process the Combobox, for example, as follows:
import org.xml.sax.*;
import org.xml.sax.helpers.*;
import java.util.*;
public class UIConfHandler extends DefaultHandler{
     //For knowing to which element am I adding content
     private Stack tagStack = new Stack();
     //An interface that allows me to access content to my elements
     private UIElement element;
     //A container of the elements retrieved from the file
     private Vector envelope;
     public UIConfHandler(){
     public void startDocument() throws SAXException {
          envelope = new Vector();
     public void endDocument() throws SAXException {
     public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException{
          System.out.println("Beginning of the element");
          if(qName.equals("combobox")){
               //I just cast my element as a Combo Box element, and add specific content from within the attributes of the tag
               element = new ComboBoxElement(attributes.getValue("id"),attributes.getValue("label"),attributes.getValue("type"),"");
          else{
          //And I add the reference to which element am I currently in via the stack
          tagStack.push(qName);
     public void characters(char[] ch, int start, int length) throws SAXException{
          String chars = new String(ch, start, length).trim();
          if(chars.length() > 0){
               if((qName.equals("value"))){
                    if (element instanceof ComboBoxElement ){
                         //I add a specific value to a Vector inside my ComboBox content
                         ((ComboBoxElement) element).addElementToVector(chars);
               else{
                    System.out.println("Content with no action specified.");
     public void endElement(String uri, String localName, String qName, Attributes attributes) throws SAXException{
          System.out.println("End of the element");
          if(qName.equals("combobox")){
               //After all the values are added inside the internal vector of the element, add the element to the container
               envelope.addElement(element);
          //And remove the combobox element from the stack
          tagStack.pop();
     public Vector getEnvelope() {
          return envelope;
}Afterwards, I would use this element to create a ChoiceGroup to be viewed in a MIDlet. The problem is that the code in endElement is never called. Does somebody know what this could be?
