work

In my stupidity innocence I just hoped that deploying the application on the new JBoss (from 4.2.2-GA to 5.1.0-GA) should be just a simple matter of changing paths in ant. Here are some problems I encountered and was able to fix. application.xml The format of this file has changed from: <?xml version="1.0" encoding="UTF-8"?> <application xmlns="http://java.sun.com/xml/ns/j2ee" version="1.4" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com /xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/application_1_4.xsd"> <display-name>My application</display-name> <description>My server interface</description> ... to <?xml version="1.0" encoding="UTF-8"?> <application xmlns="http://java....

Logout messages If you are opening a terminal to a different server or do a su in a terminal then on logout you will be required to enter your password in order to confirm the logout action. Since the polkit-gnome-authorization does not work with the new polkit version which ships with ubuntu and the polkit-auth command does not seems to work either I’ve found after some research that the solution resides in editing the /usr/share/polkit-1/actions/org....

Since my migration to thunderbird I did not had many things to complain but one of the remaining things was the date format. I am expecting to have something like DD/MM/YY or at least DD MMM YYYY. I did not imagined this could be something else than configuration somewhere. Or not… After some digging I found out there is no way to configure the date string but the only way to change the date is to change the locale the application is using....

This ubuntu installation was the bit of fun expected after a few tiresome weeks so I grabbed the cd while still hot and started the installation. As usual the install went smoothly except the fact that I probably mistyped my usual password so I had to modify the /etc/shadow afterward to log in. I was not expecting many changes but there are some graphical changes, the gdm seemed changed and after login I was greeted with a “DISK HAS MANY BAD BLOCKS” message since now there is a tool (palimpsest) which reads the S....

This is a very short example I managed to do in not a very long time which does the following things: opens an openoffice draw document modifies a field exports it as ps (using print to file) Ah, and it does that from an external python program. The setup In order to run a python script you need: to set the python path to include the uno lib and start a ooffice server...

Facand de curand ordine pe aici am dat peste harta blogosferei si am incercat sa-mi confirm raspunsurile la 2 intrebari: cum a evoluat numarul de posturi? cat de mult se vorbeste in ele despre biciclete? Rezultatul: Bloguri si biciclete 2008 - 2009 Explicatii Primul grafic reprezinta numarul de posturi pe saptamana pentru toate blogurile cuprinse in harta pe perioada oct. 2008 – aug. 2009 Al doilea grafic reprezinta precentual in cate din aceste posturi s-a vorbit despre biciclete....

2 short tricks on ubuntu linux (9.04 Jaunty): Install a .ttf font #create a fonts dir sudo mkdir -p /usr/share/fonts/truetype/myfonts #copy the font sudo cp myFont.ttf /usr/share/fonts/truetype/myfonts #update fonts cache fc-cache -fv Note: if you are using an application don’t expect the fonts to be refreshed dynamically, just restart it. Create a cisco vpn connection apt-get install vpnc Create a /etc/vpnc/myvpn.conf. If you want to convert an existing .pcf file check this article....

After quite some time of development we realised that our application flex has grown quite large, both in functionality and size. I should have chosed to develop it in GWT since I think we could not have done even 30% of the functionality and it would have been simpler :). Joke aside the size of all the modules has grown over 50M. These are some steps I have found in order to reduce the size....

Using a radio button as a data grid cell renderer is an example of a more complex usage of data grid cell renderers. This is one way to achive this in a not very complicated way: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"> <mx:Script> <![CDATA[ public var dp:XML = <users> <user> <name>one</name> <main>true</main> </user> <user> <name>two</name> <main>false</main> </user> <user> <name>tre</name> <main>false</main> </user> </users>; ]]> </mx:Script> <mx:VBox> <mx:DataGrid dataProvider="{dp.user}" width="400"> <mx:columns> <mx:DataGridColumn headerText="Name" dataField="name"/> <mx:DataGridColumn headerText="Main"> <mx:itemRenderer> <mx:Component> <mx:HBox horizontalAlign="center"> <mx:Script> <!...
