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

Somehow System.getProperty("line.separator") doesn't work. Not sure why
yet.

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?
