String Index out bound exception : 34

[Sanjeev]

dear gurus

i m reading XML file in the form of string.

below is the code.

private void parseDocument(String receivedMessage) {
//get a factory
SAXParserFactory spf = SAXParserFactory.newInstance();
try {
//get a new instance of parser
SAXParser sp = spf.newSAXParser();

//parse the file and also register this class for call backs
sp.parse(new InputSource(new
ByteArrayInputStream(receivedMessage.getBytes())), this);

}catch(SAXException se) {
}catch(ParserConfigurationException pce) {
}catch (IOException ie) {
}
}

In this code i m getting error on line started with "sp.parse(..."

could any one help why i m getting this error..

thanking in advance
