I've solved this with this not so elegant solution: As you can see, I
basically reading the data as ByteArray and does the EBCDIC coversion if
the os.name = OS/400.

private static List<String> readStdio(InputStream is) throws
Exception {

BufferedInputStream bis = new BufferedInputStream(is);
ByteArrayOutputStream bao = new ByteArrayOutputStream();
List<String> rs = null;

int result = bis.read();
while(result != -1) {
byte b = (byte)result;
result = bis.read();

String str;
if (System.getProperty("os.name").equals("OS/400"))
str = bao.toString("Cp037");
str = bao.toString();

rs = new ArrayList<String>(Arrays.asList(str.split("\n")));

return rs;

I've found that reading of the Process.getInputStream() works fine if
class is instatiated from a PC. However, it failed to read
Process.getInputStream() data correctly when the class is instatiated
iseries. I then added some codes the print the read result in hex and,

appearantly, when the class is instantiate from iseries, the result is
back in EBCDIC encoding format and the BufferedReader is attempting to
it as ASCII. Well, that ain't going to work :(.

Has anyone encountered this problem before? How can I resolve this so
this class can be run on both iseries and PC?
