String str = "print me";
//always give the path from root. This way it almost always works.
String nameOfTextFile = "e:\\jsp\\write.txt";
try {
  PrintWriter pw = new PrintWriter(new FileOutputStream(nameOfTextFile));
  pw.println(str);
  //clean up
  pw.close();
} catch(IOException e) {
  out.println(e.getMessage());
}

源码如上，文件运行完毕之后，打开e:\\jsp\\write.txt，可以看到print me已经被写在了文件当中。该例程测试通过，如有问题，可联系我。
