Today, I was checking Java.net web page. I read the article of Distributing a Java Web Start Application via CD-ROM
Well, that is my initial thinking of its possible usage scenarios:
1- It could be used for installation CDs
2- It could be used for making a demo CD with and embedded server (Tomcat or Glassfish) and the application deployed to it. And having this CD sent to the client
3- It could be used for making an auto-update CD for an already deployed application (sending the application update on a CD to the client which all he has to do is to insert it into the CD-Rom and it would update the already deployed application).
