Launch Instructions

JExpress' installer created an easy way for you to launch JExpress during the installation.

You'll find a shortcut under Program Files | JExpress. You'll also find an icon for JExpress on your desktop.

JExpress created a double-clickable exe during its installation. If you're having any trouble starting JExpress, then modify the properties file in the JExpress subdirectory (i.e., you're trying to launch to use jre.exe/java.exe instead of jrew.exe/javaw.exe. You can also create diagnostic log called startapp.log in the JExpress directory to see what's happening behind the scenes.

Mac OS X
You'll find an icon for JExpress on your desktop.


A launch script in the directory you specified for JExpress contains a launch script named jexpress if you're running under Unix.

If you have KDE installed on your system, then JExpress also created a menu item under the Development menu.

Other OSes

If you are operating under another environment, then you'll need to add the directory where you installed JExpress to the classpath. If you're using the JRE, then you can simply use the -cp switch to set the classpath. The main class for JExpress is called com.denova.JExpress.Builder.JExpress.


Command using JRE 1.5.x or later:

java -cp .:icons com.denova.JExpress.Builder.JExpress
