Java Web Application & UTF-8

This is probably the best way to set encoding for all jsp pages, you should also save jsp files in UTF-8 encoding or whatever you need.

<jsp-config>
<taglib>
<taglib-uri>http://java.sun.com/portlet_2_0</taglib-uri&gt;
/WEB-INF/tld/liferay-portlet.tld
</taglib>
<jsp-property-group>
<url-pattern>*.jsp</url-pattern>
<page-encoding>UTF-8</page-encoding>
</jsp-property-group>
</jsp-config>

Google Maps Internationalization

English: Wordmark of Google Maps

Google Maps API supports internationalization of user interface and locations names. In order to add language definition to our map we have to provide additional parameter language to <script> declaration.

<script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?sensor=false&language=sl"></script>

Source:
https://developers.google.com/maps/documentation/javascript/basics

With this kind of language declaration we can define only one language (if we forget JavaScript DOM manipulation). What we need is dynamically loaded Google Maps API and Google Loader is the right choice for this kind of job. It is capable of loading several JavaScript libraries like Google Maps API, Google Data APIsGoogle Visualization API… For more information click here. Google Loader API requires <script> declaration in header of HTML  document:

<script type="text/javascript" src="https://www.google.com/jsapi"></script>

And this is an example of dinamicly loaded Goolge Maps API with provided language and callback function which builds a new map:

<script type="text/javascript" src="https://www.google.com/jsapi">  function mapsLoaded() { ... }
   google.load("maps", "3", {"callback" : mapsLoaded, "language": "sl", "other_params": "sensor=false"});
</script>

And what is wrong whit this code?

The language is never set properly. What actually works is language declaration inside other_params like this:

<script type="text/javascript" src="https://www.google.com/jsapi">  function mapsLoaded() { ... }
   google.load("maps", "3", {"callback" : mapsLoaded, "other_params": "sensor=false&language=sl"});
</script>

Do not forget sensor parameter!

Liferay on GlassFish 3.1.2 [bug]

GlassFish Logo Java http https web server

Due to bug in GlassFish 3.1.2 we are unable to upload files in Liferay 6.1 portal. The problem should be resolved in next GlassFish release. Liferay 6.1 bundle already comes with older version of GlassFish, but for manual installations we have to set up GlassFish server, database, deploy portal .war file and try upload several files, before we notice the bug.

Upgrading to Ubuntu 12.04 LTS

Ubuntu released a new version of popular OS with Long Term Support. There is a new head-up display (HUD) with even more minimalistic design, video search enhancement and updated software center.

Ubuntu Software Center now allows you to sync all installed apps with multiple computers, which can be very useful after fresh install.

Video Lens is a new video search feature. In addition to local search it also query online services like YouTube. I don’t see my self using this feature as I hardly got used to Unity.

Virtual Hard Drive resizing

VirtualBox is one of the most useful virtualization software available for free.

Creating virtual machine is easy, just a few clicks and we are able to explore new operating system. What we need to sacrifice is some processor time, RAM memory and a few GBof hard drive. These resources can be dynamically allocated, even the hard drive.

VirtualBox

Recently, I had set up a developement environment on a virtual machine running Windows 7. Hard disk has been dynamically allocated at 30 GB. I was running GlassFish server with MySQL database and Eclipse IDE. I also had installed ruby with rails framework along and Aptana Studio. As you can imagine VHD become insufficient. As I couldn’t afford to install everything from scratch again, I decided to extend virtual disk.
