hi,

In my RAP project, pdf file is created by iText dynamically as inputstream and displayed in browser. it can work well in IE with Adobe Reader, but Chrome gives errors as below:

rap-client.js:106 Resource interpreted as Document but transferred with MIME type application/pdf


the code snippet is:

InputStream pdfData = (InputStream) RWT.getUISession().getHttpSession().getAttribute(PrintDialog.PDF_KEY);
		//HttpServletResponse resp = RWT.getResponse();
		
		response.setContentType("application/pdf");
		response.setHeader("Cache-Control", "no-cache"); // HTTP 1.1
		//response.setHeader("Cache-Control", "max-age=0");
		response.setHeader("Content-Disposition", "inline");
		//response.setHeader("content-length", pdfData.);
		
		ByteArrayOutputStream bos = new ByteArrayOutputStream();
		int next = pdfData.read();
		while (next > -1) {
			bos.write(next);
			next = pdfData.read();
		}
		bos.flush();
		byte[] result = bos.toByteArray();

		try {
			ServletOutputStream out = response.getOutputStream();
			out.write(result);
			out.close();
		} catch (IOException e) {
			e.printStackTrace();
		}


ServiceManager manager = RWT.getServiceManager();
manager.registerServiceHandler(SERVICE_HANDLER, new PDFServiceHandler());
browser.setUrl(manager.getServiceHandlerUrl(SERVICE_HANDLER)+"&random="+RandomUtils.nextLong()+"#toolbar=1&view=FitH,top");


Thanks
