私はブラックベリーでSAXパーサーを使用しようとしており、このチュートリアルを使用しました:
http://javarevisited.blogspot.com/2011/12/parse-read-xml-file-java-sax-parser.html#ixzz2OZJ6vB8O
これは私の構文解析クラスのコードです
import java.io.ByteArrayInputStream;
import java.io.InputStream;
import net.rim.device.api.xml.parsers.SAXParser;
import net.rim.device.api.xml.parsers.SAXParserFactory;
import org.xml.sax.Attributes;
import org.xml.sax.SAXException;
import org.xml.sax.XMLReader;
import org.xml.sax.helpers.DefaultHandler;
public class Samp extends DefaultHandler{
String url = "http://ravee.clientarea.in/exhibitr/getData.php?db_table=events";
TheVectorClass tcv ;
boolean currentElement = false;
String currentValue = "";
// private Account acct;
private String temp;
public void parsingmethod()
{
System.out.println("in parsingmethod");
SAXParserFactory spfac = SAXParserFactory.newInstance();
//Now use the parser factory to create a SAXParser object
//Create an instance of this class; it defines all the handler methods
Samp handler;
try {
SAXParser sp = spfac.newSAXParser();
handler = new Samp();
// XMLReader = new
System.out.println("url is "
+ url );
InputStream is = new ByteArrayInputStream(url.getBytes());
//Finally, tell the parser to parse the input and notify the handler
System.out.println("value of is " +is);
System.out.println("value of is " +handler);
// System.out.println(" sp.parse(is, handler) "+
// here in next line I get the error
sp.parse(is, handler);
} catch (Exception e) {
// TODO Auto-generated catch block
System.out.println("here in samp error 2");
e.printStackTrace();
System.out.println("e.gemessage 2 " +e.getMessage() );
}

}
/*
* Every time the parser encounters the beginning of a new element,
* it calls this method, which resets the string buffer
*/
public void startElement(String uri, String localName,
String qName, Attributes attributes) throws SAXException {
temp = "";
System.out.println("reached");
if (qName.equalsIgnoreCase("parameters")) {
// acct = new Account();
// acct.setType(attributes.getValue("type"));
System.out.println("val " +temp);
}
}
/*
* When the parser encounters the end of an element, it calls this method
*/
public void endElement(String uri, String localName, String qName)
throws SAXException {
if (qName.equalsIgnoreCase("nme")) {
// add it to the list
// accList.add(acct);
System.out.println("val1 " +temp);
}
else if (qName.equalsIgnoreCase("descriptin")) {
// acct.setName(temp);
System.out.println("val1 " +temp);
}
}
私のスクリーンクラスでそれを次のように呼びます
public final class HomeScreen extends MainScreen
{
/**
* Creates a new HomeScreen object
*/
Samp smp;
String elemtn;
Connection coon;
boolean currentElement = false;
String currentValue = "";
HomeScreen hm;
// Samp smp ;
TheVectorClass tcv ;
public HomeScreen()
{
// Set the displayed title of the screen
setTitle("parsing ");
final TheVectorClass tcv ;
// hm = new HomeScreen();
smp = new Samp();
try {
MainScreenUpdaterThread thread = new MainScreenUpdaterThread(this , smp);
thread.start();
System.out.println("before");
// smp.parsingmethod();
System.out.println("after");
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
System.out.println("e.get message "+e.getMessage());
}
}
}
そして私が得ているエラーは

このエラーを解決するにはどうすればよいですか?
