java.io.UTFDataFormatException

[simon]

When I try to create a file and try to parse it an error appears
this is my code:

FileWriter fw =null;
File file=null;
BufferedWriter bw=null;
String nodeName="";
String nodeval="";
System.out.println("XML String" + XMLString);
try {
double ran = Math.random();
fw= new FileWriter("content.xml");
file = new File("content.xml");
bw = new BufferedWriter(fw);
bw.write(XMLString);
bw.flush();
Document doc = docBuilder.parse(file); --

and the exception is that:

java.io.UTFDataFormatException: Invalid byte 1 of 1-byte UTF-8 sequence.

try:

fw = new OutputStreamWriter(new FileOutputStream("content.xml"),"utf-8");
