openSUSE 11.0 was the best Linux distribution I’ve ever used. I was hoping openSUSE 11.1 would continue the great strides of late, but it’s a bit of a mixed bag. One of the most frustrating things for me is that support for remote access is falling by the wayside. VNC used to be better integrated Read More
Just a few to post for right now, but this entry may grow later. # change to the real directory if in a linked directory alias rd=’cd `pwd -P`’ # search for and open file in sublime function s { FILE=$1; test -f $FILE || FILE=`find . -name $FILE`; sublime $FILE; }
GWT uses what it calls a ClickListener instead of the standard HTML onclick attribute. The normal way to use a GWT CLickListener would be as follows: focusWidget.addClickListener(new ClickListener() { public void onClick(Widget sender) { // do something here } }); Unfortunately, this seems not to work on an HTML Element. Luckily, you can use JSNI Read More
Frutiger Linotype is a very cool premium font. You may recognize it as the font that the flickr logo was created with. In order to get a free copy, all you need to do is download Microsoft Reader.
I’ve connected both a Syntax Olevia and an LG TV to my openSUSE desktop. Neither have worked well because they caused the default font size to be unusably large.

Validation is an important part of any web framework because it is one of the most painfully repetitive things to have to continually recreate. In Struts 2, validation is handled by creating an Action-validation.xml file. So, if we have an AddUser Action then we would create an AddUser-validation.xml file: <!DOCTYPE validators PUBLIC “-//OpenSymphony Group//XWork Validator Read More
The struts.xml file defines the relationship between actions and .jsp views, the inclusion of interceptors, and possible result types. It’s essential that you be able to handle at least basic configuration changes, so we’ll demonstrate the most important and frequently used below. Packages: Extension, Namespaces, and More For more complex applications, you will likely want Read More
Interceptors are my favorite aspect of Struts 2. They inspect and/or act on a user’s request. There are three main uses cases that I’ll discuss here: intercepting before the action, between the action and view, and after the view. At the end, I’ll show you how to add your brand spankin’ new interceptor to your Read More
