JWS is downloading the Application every time when I launch from desktop

Question

Hello All,
We are Facing a strange issue with the JRE6U14 version. first let me tell you about the jnlp config file we have. we Use JWS to install a SWT Based application. For that we are using two JNLP descriptors . One is the main JNLP <application-desc> and the other is <installer-desc> which we use inside it.
The application is working fine with the JRE6u13. with no exceptions on a windows XP and Vista systems with IE 6&7 browsers . Recently one of our client installed JRE6u14 and they upgraded their IE browser to IE8, after that they installed our application also through Java Web start. Application got installed without any problem , but the problem they faced is when they try to open the application for the next time from the application shortcut on desktop, web start is not launching the application directly ,instead it is trying to download the application again.
Our jnlp file has the following configuration for <shortcut> element
*<shortcut online="true">*
*<desktop/>*
*<menu submenu="Course Builder"/>*
*</shortcut>*
This was working perfect in JRE6u13 but the mess started with JRE6U14 on windows Vista system with IE 8 . This behavior is not consistent again, the JRE6u14 works fine with IE 7 on windows XP. I have no clue about why it fails , Is any body faced this type of issue with Web start deployment.
Any suggestion or solution will be much appreciated
Thanks
Pavan

Hello Jorge,
Make sure your computer's software is completely up to date by going to Apple Menu > Software update.
Remove the following files to the trash and restart the computer (do not empty the trash until you are sure the issue is resolved):
Home > Library > Preferences > com.apple.ical (There may be more than one of these files. Remove them all.)
Home > Library > Caches
Home > Library > Calendars > Caches (There may be more than one of these files. Remove them all.)
If after restarting the same thing happens try testing iCal in a new user account http://docs.info.apple.com/article.html?path=Mac/10.6/en/8235.html.
If the issue only happens in your user account follow http://support.apple.com/kb/TS1627.
If the issue happens system wide reinstall iCal by moving the iCal application to the trash and following: http://docs.info.apple.com/article.html?path=Mac/10.6/en/19535.html.
Hope that helps.
