URI is not hierarchical - Java

There are some problems when running the build jar of your project compare to running it in an IDE, when resources such as images is called within the build jar, usually we just use getClass#getResource("path/of/the/image.jpg") in the IDE, and when you build the project and execute the jar the "URI is not hierarchical" is thrown. One way to fix this is retrieve it as a resource-stream like.

InputStream dx = this.getClass().getResourceAsStream("/com/sample/images/default_image.png");

Image sm = ImageIO.read(dx).getScaledInstance(width, height, Image.SCALE_SMOOTH);

You can then us the Image in any component.

Catch ConstraintViolationException in Hibernate and get the Error message

I am developing a Java desktop app and I'm using Hibernate on it. In the documentation of Session#save() it only returns Serializable and I have to get a response object when it throws an exception during save call. Heres what I did.

I enclose it with a try catch, and when it receives an exception just get the ConstraintViolationException#getMessage(1) object of it. You can directly return the Object or encapsulate it with your custom object.

Options Menu won't show in ICS(Ice Cream Sandwich)

I am developing an application in android and decided to code at the options menu, to add some preferences/settings. As I want to see the output of my code, I notice that the options menu isn't showing, no matter how I override the onCreateOptionsMenu(..), and decided to hit google. This link gives the ANSWER.

You must change the targetSdkVersion to <= 10 in the manifest.xml, and run the code again, and successfully the options menu showed.

Access Denied for phpmyadmin in XAMPP 1.8.1 - Ubuntu

I installed the XAMPP 1.8.1 for linux in my ubuntu and ran http://localhost/phpmyadmin, and suddenly it gives an error Access Denied! Really in my localhost? yeah!

The Fix:

1. Navigate to the file "httpd-xampp.conf" mine is "/opt/lampp/etc/extra/httpd-xampp.conf"
2. Add "Require all granted" to this block of code
   

   #
   
       AllowOverride AuthConfig Limit
       Order allow,deny
       Allow from all
   
   #
   

3. The result will be
   

   #
   
       AllowOverride AuthConfig Limit
       Order allow,deny
       Allow from all
       Require all granted
   
   #
   

4. Then restart your lampp
   

   #
   sudo /opt/lampp/lampp restart
   #
   

Manual Install Eclipse - Ubuntu

I'm tired of searching in the internet on how to manually install eclipse. I am not using the Ubuntu Software Center to download eclipse because I want the Eclipse Helios to be installed.

1. Download the Eclipse Helios. You can download any package you want. I downloaded the eclipse-jee-helios-linux-gtk.tar.gz 
2. Extract and copy it to the /opt directory
   

   
   sudo tar -vxzf eclipse-SDK-3.7-linux-gtk-x86_64.tar.gz -C /opt
   cd /opt
   sudo chown -R root:root eclipse
   sudo chmod -R +r eclipse
   
   

3. You can also change the root:root to user:user
4. Create an executable
   

   sudo touch /usr/bin/eclipse
   sudo chmod 755 /usr/bin/eclipse
   sudo gedit /usr/bin/eclipse

5. Paste this to gedit and save
   

   #!/bin/sh
   #export MOZILLA_FIVE_HOME="/usr/lib/mozilla/"
   export ECLIPSE_HOME="/opt/eclipse"
   
   $ECLIPSE_HOME/eclipse $*
   

6. Create a shortcut
   

   sudo gedit /usr/share/applications/eclipse.desktop
   

7. Paste to gedit
   

   [Desktop Entry]
   Encoding=UTF-8
   Name=Eclipse
   Comment=Eclipse IDE
   Exec=eclipse
   Icon=/opt/eclipse/icon.xpm
   Terminal=false
   Type=Application
   Categories=GNOME;Application;Development;
   StartupNotify=true
   

8. And launch Eclipse for the first time
   

   sudo eclipse/eclipse -clean
