Netbeans和Shell窗口之间的行为不同

Question

I wrote a small program in Java using Netbeans 8.02 (JDK8; java version 1.8.0_45). It reads an XML file (in UTF-8 encoding), finds and replaces the character "&", parses the file and signs it.

Executing this program from Netbeans it's all right. Executing the same program from windows XP shell i meet errors about the encoding of the file to be signed. Executing the same program from windows 7 shell every thing is fine.

somebody knows what cause this different behavior?

Answer 1

to minimize the distance between this different behaviors, and thus avoiding errors of BOM and charset, I solved in this way:

f = new File(PatInputFile);
String sif = readfile(PatInputFile,StandardCharsets.UTF_8);
byte[] contentInBytes = sif.replaceAll("&", "&").getBytes("UTF-8");
FileOutputStream fop =new FileOutputStream(f);
fop.write(contentInBytes);
fop.flush();
fop.close();

where

 private static String readfile(String path, Charset encoding)  throws IOException 
{
  byte[] encoded = Files.readAllBytes(Paths.get(path));
  return new String(encoded, encoding);
}

and so on parsing and signing the file "f" .
