    <p>HTML file uploads use by default <a href="http://www.faqs.org/rfcs/rfc2388.html" rel="nofollow noreferrer">the <code>multipart/form-data</code> request encoding</a> (this is in order to be able to upload multiple files and/or to mix normal input field values in <strong>one</strong> request). You're however not parsing and extracting the individual form data parts from the request body, instead you're reading and writing the <em>entire</em> request body plain unmodified to a file. </p> <pre><code>is = request.getInputStream(); fos = new FileOutputStream(new File(realPath + "/" + filename), false); IOUtils.copy(is, fos); </code></pre> <p>This is indeed not ever going to work. That you said that it works in FF/Chrome is beyond me. Perhaps you're misinterpreting the results or do not have tested it in those browsers with binary files at all.</p> <p>You need to use <a href="http://commons.apache.org/fileupload" rel="nofollow noreferrer">Apache Commons FileUpload</a> to extract the parts from a <code>multipart/form-data</code> request. Or, when you're already on Servlet 3.0, you could also use the Servlet API provided <a href="http://download.oracle.com/javaee/6/api/javax/servlet/http/HttpServletRequest.html#getParts%28%29" rel="nofollow noreferrer"><code>HttpServletRequest#getParts()</code></a> method.</p> <h3>See also:</h3> <ul> <li><a href="https://stackoverflow.com/questions/2422468/how-to-upload-files-in-jsp-servlet/2424824#2424824">How to upload files to server using JSP/Servlet?</a></li> <li><a href="https://stackoverflow.com/questions/7114087/html5-file-upload-to-java-servlet">HTML5 File Upload to Java Servlet</a></li> </ul> <hr> <p><strong>Unrelated</strong> to the concrete problem, you've another problem with the code posted so far. You're storing uploaded files in the web content of the expanded WAR. This is far from a solid permanent storage location. Everytime when you redeploy a new WAR, all those files will get lost. You'd need to backup them everytime which is plain clumsy and error prone. Rather store them in a fixed location outside the expanded WAR folder.</p> <h3>See also:</h3> <ul> <li><a href="https://stackoverflow.com/questions/7274517/java-ee-best-way-to-get-real-path-to-uploaded-files">Java EE - Best way to get real path to uploaded files?</a></li> </ul>

    1. COThank you for answer. I dont quite understand what you mean by why the way i do it should not work. I got the OctetStreamReader.java from valums homepage together with the whole package and only modified it a little:[link](http://valums.com/ajax-upload/) Also i tried using Apache Commons FileUpload and it worked fine when i submitted the picture together with the form using: <input type="file" name="file" /> <input type="submit" /> But it did not work with the Ajax Uploader and i kinda need a dynamic pic upload before submitting the whole form. Thats why i tried to go back to this

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).
