Netbeans Look and Feel Problem

Nov 4

Posted by admin in Java, Netbeans | Comments off

How to fix Netbeans 7.4 (in my case) problems with Linux Mint Cinnamon:

Download JGoodies Looks and JGoodies Common and extract zip files somewhere.

Change your <NETBEANS-FOLDER>/etc/netbeans.conf by adding “–cp:p /home/ehurmuzov/java/jgoodies/jgoodies-looks-2.5.3/jgoodies-looks-2.5.3.jar –cp:p /home/ehurmuzov/java/jgoodies/jgoodies-common-1.6.0/jgoodies-common-1.6.0.jar  –laf com.jgoodies.looks.plastic.Plastic3DLookAndFeel” to the netbeans_default_options line:

netbeans_default_options=”-J-client -J-Xss2m -J-Xms32m -J-XX:PermSize=32m -J-Dapple.laf.useScreenMenuBar=true -J-Dapple.awt.graphics.UseQuartz=true -J-Dsun.java2d.noddraw=true -J-Dsun.java2d.dpiaware=true -J-Dsun.zip.disableMemoryMapping=true –cp:p /home/ehurmuzov/java/jgoodies/jgoodies-looks-2.5.3/jgoodies-looks-2.5.3.jar –cp:p /home/ehurmuzov/java/jgoodies/jgoodies-common-1.6.0/jgoodies-common-1.6.0.jar  –laf com.jgoodies.looks.plastic.Plastic3DLookAndFeel”

Here is the result:

Before:

nb-before-menu

 

After:

nb-after-menu

 

Much better, isn’t it?

Get Geo Location from Image File

Nov 11

Posted by admin in Java, Software | Comments off

 

public static GeoLocation getMetadata(String filename) {
    GeoLocation gl = null;

    try {
        File file = new File(filename);
        Metadata metadata = ImageMetadataReader.readMetadata(file);

        for (Directory directory : metadata.getDirectories()) {
            if (directory instanceof GpsDirectory) {
                GpsDirectory gpsd = (GpsDirectory)directory;
                gl = gpsd.getGeoLocation();
            }
        }

    } catch (ImageProcessingException | IOException ex) {
        Logger.getLogger(ImageHelper.class.getName()).log(Level.SEVERE, null, ex);
    }
    return gl;
}

 

Very simple.
The example uses metadata extractor in Java.

JSF 2.0 Composite Components #1

Nov 27

Starting with something very easy – label. We’ll make it bold to separate from input/output text.

Usual directories in the web project:


<Web Pages>
<Web Pages>/WEB-INF
<Web Pages>/resources
<Web Pages>/resources/css
<Web Pages>/resources/images
<Web Pages>/resources/realsoft

In bold is the directory where I’ll put my custom components. Choose a suitable for you name. Below is label.xhtml file:

<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

  <cc:attribute name="value" required="true" />
  <cc:attribute name="for" required="false" />

<!-- IMPLEMENTATION -->
