    <p>I am trying to post files as part of POST array with Java to a remote server with this code:</p> <pre><code>public void executeMultiPartRequest(String urlString, File file, String fileName, String login, String password, String project) throws Exception { RequestConfig requestConfig = RequestConfig.custom().setConnectTimeout(30 * 1000).build(); HttpClient client = HttpClientBuilder.create().setDefaultRequestConfig(requestConfig).build(); HttpPost postRequest = new HttpPost (urlString) ; try { //Set various attributes MultipartEntity multiPartEntity = new MultipartEntity () ; multiPartEntity.addPart("login", new StringBody(login != null ? login : "")) ; multiPartEntity.addPart("password", new StringBody(password != null ? password : "")) ; multiPartEntity.addPart("project", new StringBody(project != null ? project : "")) ; multiPartEntity.addPart("fileName", new StringBody(fileName != null ? fileName : file.getName())) ; FileBody fileBody = new FileBody(file, "image/jpeg") ; //Prepare payload multiPartEntity.addPart("attachment", fileBody) ; //Set to request body postRequest.setEntity(multiPartEntity) ; //Send request HttpResponse response = client.execute(postRequest) ; //Verify response if any if (response != null) { System.out.println(response.getStatusLine().getStatusCode()); HttpEntity resEntity = response.getEntity(); System.out.println(response.getStatusLine()); if (resEntity != null) { System.out.println(EntityUtils.toString(resEntity)); } if (resEntity != null) { resEntity.consumeContent(); } client.getConnectionManager().shutdown(); } } catch (Exception ex) { System.err.println(ex); // returns null as the cause is nonexistent or unknown. System.err.println("Cause = " + ex.getCause()); } } </code></pre> <p>It all goes fine when working with <em>localhost</em> and I get my file in the post array. Yet when working with a <em>remote server</em>, <code>$_post['attachment']</code> displays as empty but the files get saved as always identical four bytes of Cyrillic text. I'm a complete newbie with Java and just trying to get this small piece to work in par with my PHP server-side stuff. Why is this happening? Can it be that the client doesn't have the time to properly send the data, or is it more likely that the server is not accepting it? The code processing the requests is similar on <em>localhost</em> and the <em>remote server</em>.</p>

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.
