A Smart Client is a native application, that gets launched from the Servoy Application Server using Java WebStart technology. The Smart Client installs itself on the client machine on first launch and from there onwards will keep itself up to date, by checking for updates on each consecutive launch.

The JRE can also be manually downloaded and installed. See Java runtime for more information.

Installing Smart Clients

Smart Clients install themselves on first launch. On first launch, the Java Web Start process will install the Smart Client in a cache on the client machine. On subsequent starts, the Java Web Start mechanism will check to see if the application is already cached and will start from the cache if available.

...

Desktop integration
The Smart Client can automatically integrate with the desktop of the client machine. Whether or not this happens depends on both client-side settings in the Java environment as well as server-side settings on the Application Server. See Java WebStart settings for more information on the client-side Java WebStart settings and #Smart Client settings for more information on the Application Server settings.

Removing Smart Client installations

Smart Clients are launched via Java WebStart installed on the client machine. Java WebStart caches every application that it launches. This cache can e viewed through the Java Control Panel or the cache viewer can be opened directly from the commandline using the following command:

Code Block

javaws -viewer 

For more information on the Java control Panel, see #Java Control Panel

Starting Smart Clients

By default, the Servoy Application Server comes with a web page for starting Smart Clients, located at {serverUrl}/index.html. This web page also provides a link to check if a Java Standard Edition Runtime Environment is installed.

Smart Client footprint

A Smart Client has a very small footprint on the client machine. For startup performance reasons, both the Smart Client libraries as well as the Servoy Solution binaries are cached.
