LWUIT4IO (v1.5) ConnectionRequest's readResponse() Issue - Nokia SDK 2.0 - java-me

Question

I have been porting an existing J2ME mobile app, that allows users to view archived news videos, to the latest Nokia SDK 2.0 platform for Series 40 full-touch devices.
I am using both the LWUIT and LWUIT4IO technologies for the UI and Network functionalities of the application respectively.
The app has been tested to work on the S40 5th Edition SDK platform emulator. Extending LWUIT4IO's ConnectionRequest class and utilizing LWUIT's XMLParser, the app can successfully send a HTTP request and get the expected response data from a web service that basically returns an XML-formatted type of feed (containing necessary metadata for the video) (Here's the URL of the web service: http://nokiamusic.myxph.com/nokianewsfeed.aspx?format=3gp)
But for some reason, this is not the case when trying to run the app on the latest Nokia SDK 2.0 platform. It throws a java.lang.NullPointerException upon trying to parse (XMLParser.parse()) the InputStream response of the web service. When I trace the Network Traffic Monitor of the emulator of the corresponding Request sent and Response received - 0 bytes were returned as content despite a successful response status 200. Apparently the XMLParser object has nothing to parse in the first place.
I am hoping that you can somehow shed light on this issue or share any related resolutions, or help me further refine the problem.
Posted below is the code of the SegmentService class (a sub-class of LWUIT's ConnectionRequest) that connects to the webservice and processes the XML response:
public class SegmentService extends ConnectionRequest implements ParserCallback {
private Vector segments;
private Video segment;
public SegmentService(String backend) {
String slash = backend.endsWith("/") ? "" : "/";
setPost(false);
setUrl(backend + slash + "nokianewsfeed.aspx");
addArgument("format", "3gp");
}
public void setDateFilter(String date) {
System.out.println(date);
addArgument("date", date);
}
private Video getCurrent() {
if (segment == null) {
segment = new Video();
}
return segment;
}
protected void readResponse(InputStream input) throws IOException {
InputStreamReader i = new InputStreamReader(input, "UTF-8");
XMLParser xmlparser = new XMLParser();
System.out.println("Parsing the xml...");
Element element = xmlparser.parse(i);
System.out.println("Root " + element.getTagName());
int max = element.getNumChildren();
System.out.println("Number of children: " + max);
segments = new Vector();
for (int c = 0; c < max; c++) {
Element e = element.getChildAt(c);
System.out.println("segment " + c);
int len = e.getNumChildren();
System.out.println("Number of children: " + len);
for (int d=0; d<len; d++) {
Element s = e.getChildAt(d);
String property = s.getTagName();
System.out.println("key: " + property);
String value = (s.getNumChildren()>0) ? s.getChildAt(0).getText() : null;
System.out.println("value: " + value);
if (property.equals("title")) {
getCurrent().setTitle(value);
} else if (property.equals("description")) {
getCurrent().setDescription(value);
} else if (property.equals("videourl")) {
getCurrent().setVideoUrl(value);
} else if (property.equals("thumburl")) {
getCurrent().setThumbUrl(value);
} else if (property.equals("adurl")) {
getCurrent().setAdUrl(value);
} else if (property.equals("publishdate")) {
getCurrent().setPublishDate(value);
} else if (property.equals("category")) {
getCurrent().setCategory(value);
} else if (property.equals("weburl")) {
getCurrent().setWebUrl(value);
} else if (property.equals("thumburl2")) {
getCurrent().setThumb210(value);
} else if (property.equals("thumburl4")) {
getCurrent().setThumb40(value);
}
}
if (segment != null) {
segments.addElement(segment);
segment = null;
}
}
fireResponseListener(new NetworkEvent(this, segments));
}
public boolean parsingError(int errorId, String tag, String attribute, String value, String description) {
System.out.println(errorId);
System.out.println(tag);
System.out.println(value);
System.out.println(description);
return true;
}
}
