    <p>I want to display a PDF file in browser. I have the path to the pdf in JS and I am making a call to grab the PDF as a servlet from java. Here's what I have so far:</p> <p>JavaScript:</p> <pre><code>RequestManager.getJSON(Config.server + "getPDF.json?pdfPath=" + this.pathToPdfFile, (function(data){ $("#" + this.divId).append('&lt;object id="' + this.pdfObjectId + '" data="' + data + '" type="application/pdf" width="600" height="800"&gt;&lt;/object&gt;'); ResizeManager.addResizeHandler(this.pdfObjectId, this.divId, -10, -10); }).bind(this)); </code></pre> <p>Java:</p> <pre><code>@RequestMapping("/getPDF") public void pdfPathToServlet(Model model, HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { String pdfPath = request.getParameter("pdfPath"); if (pdfPath == null || pdfPath.equals("")) throw new ServletException("Invalid or non-existent file parameter in UrlServlet servlet."); if (pdfPath.indexOf(".pdf") == -1) pdfPath += ".pdf"; File pdf = new File(pdfPath); String pdfName = pdfPath.substring(pdfPath.lastIndexOf("/") + 1, pdfPath.length()); logger.debug(pdfName); ServletOutputStream stream = null; BufferedInputStream buf = null; try { stream = response.getOutputStream(); response.setContentType("application/pdf"); response.setHeader("Content-Disposition", "inline; filename='" + pdfName + "'"); FileInputStream input = new FileInputStream(pdf); response.setContentLength((int) pdf.length()); buf = new BufferedInputStream(input); int readBytes = 0; while ((readBytes = buf.read()) != -1) stream.write(readBytes); } catch (IOException ioe) { throw new ServletException(ioe.getMessage()); } finally { if (stream != null) stream.close(); if (buf != null) buf.close(); } } </code></pre> <p>My problem is that this is showing the <em>binary output</em> in my browser as text.</p> <p>I'm not sure what I am doing incorrectly. I have tried changing the header to be attachment instead of inline, but that showed the same thing. I believe I want inline though, as I wish to show it in browser and not download it.</p>

    1. COWhy is your url ending with `.json` when you return `application/pdf`?

    2. CO@Michael-O Honestly, I had put it in out of habit. The way the application is written there is one URL that the whole application runs under. It never actually changes. The .json is just normally used to prevent the page from actually redirecting to another URL that doesn't actually hold anything.

    3. COThat's not a servlet at all. That's a Spring MVC controller action.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
