XML : How to write xml file to AWS

Currently, I am writing xml file on local directory using XMLOutputFactory which accept OutputStream as a parameter. But Now I need to write xml file to AWS S3 without writing on local. I don't have local directory access.

But I am not getting "How I can write xml file to AWS S3?".

Here is my code which write xml in local directory.

  File file = new File(storeFilename);  DataOutputStream stream = null;  stream = new DataOutputStream(new FileOutputStream(file));  // Create new instance of XML straem writer  XMLOutputFactory inputFactory = XMLOutputFactory.newInstance();    try {      XMLStreamWriter writer = inputFactory.createXMLStreamWriter(                  graphMLOutputStream, "UTF8");        writer.writeStartDocument();      writer.writeStartElement(GRAPHML);      writer.writeAttribute(XMLNS, GRAPHML_XMLNS);     }    

I know how to put files on AWS S3 using PutObjectRequest() by giving file name or inputstream as a parameter.

  // send request to S3 to create folder  PutObjectRequest putobjreq = new PutObjectRequest(                  CAWSConstants.BUCKETNAME, file.getName(), file);              // put graphml file to aws  s3Client.putObject(putobjreq);       

But I don't know how to covert xml in to inputstream using xmlWriter. Which I can sent to PutObjectRequest.

Please give me hint or reference.
