    <p>Greetings folks.</p> <p>I have this weird problem. In the project I'm working on now, I need to upload a file to a FTP site. I have written many programs that do this before and they have worked just fine. But this particular site is giving me trouble. When I try to upload the file from the program, I get this to be specific:</p> <blockquote> <p>java.net.UnknownHostException: <a href="ftp://site.com" rel="nofollow">ftp://site.com</a></p> </blockquote> <p>However when I try to connect to the same site from within a browser (Chrome, IE) or from windows explorer, I'm able to find the site and login just fine. I tired posting a picture, but I was prevented from doing so as I'm a newbie.</p> <p>So I'm stumped now. If I could not connect from windows, then I can assume it is a FTP server issue. This happens to me only from the Java program. And I also know that my code works as I have used in numerous occasions before. Here is the code I use:</p> <pre><code> public void uploadFile(String fileName) throws Exception { FileTransferClient ftpClient = null; try { ftpClient = new FileTransferClient(); ftpClient.setRemoteHost(gv.ftpHost); ftpClient.setRemotePort(21); ftpClient.setUserName(gv.ftpUserName); ftpClient.setPassword(gv.ftpPassword); ftpClient.getAdvancedFTPSettings().setConnectMode(FTPConnectMode.PASV); ftpClient.connect(); ftpClient.uploadFile(gv.irp + fileName, fileName, WriteMode.OVERWRITE); } catch (Exception e) { throw new Exception("Error occured in uploadFile()\n" + e); } finally { if (ftpClient != null) { if (ftpClient.isConnected()) { ftpClient.disconnect(); } ftpClient = null; } } } </code></pre> <p>I use the edtFTPj library. My environment is Eclipse Helios (32 bit) on Java 1.6 (32 bit) running from a Windows 7 64 bit machine.</p> <p>Any insight on resolving this will be greatly appreciated. Thanks for your time.</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.
