Can I get stream for uploaded file in struts 2?

I try request.getInputStream() but when i read that stream, it does nothing.

I did it in servlet but not able to in struts2 action class.

ServletFileUpload upload = new ServletFileUpload();

		// Parse the request
		try {
			FileItemIterator iter = upload.getItemIterator(request);

			while (iter.hasNext()) {
			    FileItemStream item = iter.next();
			    String name = item.getFieldName();
			    InputStream stream = item.openStream();
			    if (item.isFormField()) {
			        System.out.println("Form field " + name + " with value "
			            + Streams.asString(stream) + " detected.");
			    } else {
			        System.out.println("File field " + name + " with file name "
			            + item.getName() + " detected.");
			        
			        //int s=-1;
			        //while((s=stream.read())!=-1){
			        //	System.out.print((char)s);
			        //}
			        // Process the input stream
			       
			    }
			}
		} catch (FileUploadException e2) {
			// TODO Auto-generated catch block
			e2.printStackTrace();
		} catch (IOException e2) {
			// TODO Auto-generated catch block
			e2.printStackTrace();
		}
	}
