    <p>I have developed a small JApplet for a site. It's the first time I do such a thing, so it's probably a stupid error or misundestanding, but I can't find out what it is.</p> <p>Here is the first class called from the HTML:</p> <pre><code>public class MapGenerator extends JApplet { private static final long serialVersionUID = 1L; private int numero_immagini; private BufferedImage[] images; private int[] floors; private static final String N_IMMAGINI = "numero_immagini"; private static final String IMMAGINE = "immagine"; private static final String PIANO_IMMAGINE ="numero_piano"; public void init() { numero_immagini = Integer.parseInt(this.getParameter(N_IMMAGINI)); images = new BufferedImage[numero_immagini]; floors = new int[numero_immagini]; for(int i=0; i&lt; numero_immagini; i++) { try { URL url = new URL(this.getParameter(IMMAGINE+i)); images[i] = ImageIO.read(url); floors[i] = Integer.parseInt(this.getParameter(PIANO_IMMAGINE+i)); } catch (IOException ioe) {} } } public void start() { Editor ed = new Editor(this.getContentPane(), images, floors); this.setSize(400, 400); this.add(ed.getPanel()); Toolkit kit = this.getToolkit(); Dimension dim = kit.getScreenSize(); this.setBounds(dim.width/4, dim.height/4, dim.width/4, dim.height/4); this.setVisible(true); this.repaint(); } } </code></pre> <p>And here is the HTML:</p> <pre><code>&lt;applet code="MapGenerator.class" archive="MapGenerator.jar" width= 400 height = 200&gt; &lt;param name=numero_immagini value=1&gt; &lt;param name=immagine0 value="IMG_20111009_171138.jpg"&gt; &lt;param name=numero_piano0 value=0&gt; &lt;/applet&gt; </code></pre> <p>In Eclipse I haven't any problem at all, but when I tried with Chrome the page show only a gray box.</p> <p>Thank to all for help.</p> <p>EDIT</p> <p>The app cannot load images from the link that I pass.</p> <p>It trows, testing with a random link image</p> <pre><code>java.security.AccessControlException: access denied (java.net.SocketPermission www.hyros.net:80 connect,resolve) java.lang.NullPointerException </code></pre>

    3. COHave you checked the security options of FireFox? What about the java console, do you see any output there? By the way, the HTML is missing some tags, or do you just omit them in the post?

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).
