    <p>I m making a <code>java rmi based application</code> where i pass and receive an ImageIcon object from the server... (the image is stored in a separate URL in server)</p> <p><strong>The function involves the following....</strong></p> <pre><code> 1. Getting the image from the server at first....(on button press A) 2. Replacing it with a image file in the client[optional]....(on button press B) 3. Remove the image with a default image[optional]....(on button press C) 4. Sending it back to the Server....................(On button press D)..... </code></pre> <p><strong>Here the image is displayed in a</strong><code>jlabel</code> <strong>called</strong><code>img_label</code></p> <p>The codes i've used are as follows.....</p> <p><strong>Variables used</strong></p> <pre><code> java.awt.Image img; javax.swing.ImageIcon CurrentImageIcon; javax.swing.ImageIcon DefaultImageIcon; // CurrentImageIcon contains the image to be displayed in the img_label.... // img is used for copying as well for scaling...... // DefaultImageIcon holds the default Image...... </code></pre> <p><strong>On Button Press A</strong></p> <pre><code> img = temp.getImage(); CurrentImageIcon = new ImageIcon(img); // Assuming temp holds the ImageIcon taken from the server....... img=img.getScaledInstance(83,85 , Image.SCALE_DEFAULT); img_label.setIcon(new ImageIcon(img)); img_label.revalidate(); img_label.repaint(); </code></pre> <p><strong>On Button Press B</strong></p> <pre><code> String url_text = jTextField.getText(); // taking the url frm the field..... CurrentImageIcon = new ImageIcon(url_text); img=CurrentImageIcon.getImage(); img=img.getScaledInstance(83,85 , Image.SCALE_DEFAULT); img_label.setIcon(new ImageIcon(img)); img_label.revalidate(); img_label.repaint(); </code></pre> <p><strong>On Button Press C</strong></p> <pre><code> img = DefaultImageIcon.getImage(); CurrentImageIcon = new ImageIcon(img); img=img.getScaledInstance(83,85 , Image.SCALE_DEFAULT); img_label.setIcon(new ImageIcon(img)); img_label.revalidate(); img_label.repaint(); </code></pre> <p><strong>On Button Press D</strong></p> <pre><code> // ImagetoSend is an ImageIcon to be sent to the Server..... ImagetoSend = CurrentImageIcon; CurrentImageIcon = null; </code></pre> <p>Now the problem i m getting is a weird one...... <strong>The image is getting embedded as i wanted on repainting when i click this button........</strong></p> <p><code>But when i download the recently uploaded image next time on Button press A....it is displayed either magnified or reduced to size even though i included the getScaledInstance method....</code> like this...</p> <p><img src="https://i.stack.imgur.com/4LMKG.png" alt="When i click the image. It embedds correctly"> <img src="https://i.stack.imgur.com/8Ibn8.png" alt="enter image description here"></p> <p>The image i am handling is a jpg image.... I even checked the image at Server directory.....No size change has occured on that file which was uploaded from client to server. But the change is observed when it is downloaded and embedded to the jlabel... <strong><em>Can Anyone help me to sort out this issue...??</em></strong></p>

    1. COFor better help sooner, post an [SSCCE](http://sscce.org). I tried to understand your question, but honestly I am completely confused as to what you are doing and what the problem is (maybe that's just me since 3 people up-voted your question).

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.
