ALEX PKB is a JAVA SWT application using browser widget. If you already have experience to run SWT application or Eclipse on your computer, you don't need to goto detail. You can modify shell script file under pkb directory and start the application directly. For linux (GTK) user: I already include swt-x.x-gtk-linux-x86.jar and swt-x.x-gtk-linux-x86_64.jar in the package. What you need is to have XULRunner properly installed and registered on the system. (Please refer to : https://developer.mozilla.org/en/XULRunner_1.9.1_Release_Notes#Installing_XULRunner ) environment variable MOZILLA_FIVE_HOME should be configed to point to XULRunner directory. You can run run_linux.sh or run_linux_x86_64.sh base on your platform. For other platform, you need to find download from http://www.eclipse.org/swt/. Unzip and find the swt.jar, place it under lib directory, modify shell script to use this swt.jar Still you need to have XULRunner properly installed and registered on the system.
