Running an Application from the Java Cache Viewer :

If you are using Java Version 1.6.0, you can run a Java Web Start application through the Java Cache Viewer. 

When Java Web Start first loads an application, information from the application's JNLP file is stored in the local Java Cache Viewer. To launch the application again, you do not need to return to the Web page where you first launched it; you can simply open the Java Cache Viewer. 

To open the Java Cache Viewer: 
Open the Control Panel.
Double click on the Java icon. The Java Control Panel opens.
Select the General tab.
Click View. The Java Cache Viewer opens.
