Re: How to resolve the problem with Runtime.getRuntime().exec returningEBCDIC data when running on iseries

Just as an FYI, your newline character on Windows is \n\r. You best to grab
the System.getProperty("line.separator") property for your split.

Other than that I'm not sure I could really think of a better way. This is
where it get's tricky with the "run everywhere" type of thing. Obviously the
best way on the IBM i to run a command would be with the CommandCall class,
but that won't work on Windows.

That being said, if you are already hard-coding something, you might want to
just use the CommandCall instead of the Runtime.getRuntime().exec() method.
Just a thought, not sure on the full scenario so this might not be an option
at all.

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;
bao.write(b);
result = bis.read();
}

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

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

return rs;
}

I've created a class that will use the Runtime.getRuntime().exec to

execute

a command on iseries when instantiated. Once the command is

sucessfully

executed, it then reads the Process.getInputStream() to get the

result.

I've found that reading of the Process.getInputStream() works fine if

the

class is instatiated from a PC. However, it failed to read
Process.getInputStream() data correctly when the class is instatiated

from

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

sent

back in EBCDIC encoding format and the BufferedReader is attempting to

read

it as ASCII. Well, that ain't going to work :(.

Has anyone encountered this problem before? How can I resolve this so

that

this class can be run on both iseries and PC?
