If Java Web Start is enabled for your deployed application client, you can launch it for testing. Simply click on the Launch button next to the application client or application's listing on the App Client Modules page in the Administration Console.
On other machines, you can download and launch the application client using Java Web Start in the following ways:
Using a web browser, directly enter the URL for the application client. See The Application Client URL.
Click on a link to the application client from a web page.
Use the Java Web Start command javaws, specifying the URL of the application client as a command line argument.
If the application has previously been downloaded using Java Web Start, you have additional alternatives.
Use the desktop icon that Java Web Start created for the application client. When Java Web Start downloads an application client for the first time it asks you if such an icon should be created.
Use the Java Web Start control panel to launch the application client.
When you launch an application client, Java Web Start contacts the server to see if a newer client version is available. This means you can redeploy an application client without having to worry about whether client machines have the latest version.
