Integration

Hi,

We had a requirement to invoke a unix shell script from B2B callout implemented class. Here is the code in implementation class:

public void execute(CalloutContext context,List input,List output)
throws CalloutDomainException, CalloutSystemException {
try {

CalloutMessage cmIn = (CalloutMessage)input.get(0);
FileOutputStream fos = null;
String inputFile = "/home/orasoad/digitalsign/input/test.txt";
String outputFile = "/home/orasoad/digitalsign/output/test.txt.gpg";
File outFile = new File(inputFile);
String str =cmIn.getBodyAsString();
fos = new FileOutputStream(outFile);
Writer out = new OutputStreamWriter(fos);
out.write(str);
out.close();
String shellFile = "/home/orasoad/digitalsign/dg.sh";
String cmd[] = new String[] { shellFile, inputFile, outputFile };
Runtime rt = Runtime.getRuntime();
Process pr = rt.exec(cmd);
int i = pr.waitFor();
BufferedReader br = new BufferedReader(new InputStreamReader(pr.getInputStream()));
StringBuffer sb = new StringBuffer();
String line;
while ((line = br.readLine()) != null) {
sb.append(line);
}

CalloutMessage cmOut = new CalloutMessage(sb.toString());
output.add(cmOut);

} catch (Exception e) {
throw new CalloutDomainException(e);
}
}


We were able to execute the unix shell script from standalone java class with same code. But some how it is not working as expected while invoking the B2B java callout.

Is it possible to invoke unix shell script from B2B callout?

Please give inputs.

Regards,
