Passing binary information in a synchronous scenario


Hi All,

I am working on a synchronous scenario where I am sending an HTTP request to third party and I am getting back the response. My requirement is that I need to pass through this response as it is from XI, no transformation is required.

This happens twice:

1) In first case, I receive the html data which is ok

2) in second case, I receive PDF data which is getting corrupted and I cant view that pdf data after my message mapping.

I am using below code in response mapping (java mapping)....

public void transform(TransformationInput in, TransformationOutput out) throws StreamTransformationException {

try {

String sourceString = "";String line ="";

String append ="";

InputStream ins = in.getInputPayload().getInputStream();

BufferedReader br = new BufferedReader(new InputStreamReader(ins, "UTF-8"));

while ((line = br.readLine()) != null){

sourceString = sourceString + line;





catch (Exception e) {

throw new StreamTransformationException(e.getMessage());



Problem is that this code is working for case 1) when I receive HTML data but in case 2) the data gets corrupted.I think I would need to pass the response as binary data (as it is) for both the cases.

Do not forget that it is a synchronous interface so I do not have the option to bypass the IR development since I am making some transformation in the request mapping.

Can anyone suggest.
