Hi all,

One of my friend download an application from the web, actually an *.exe file and few folders there in that package. He runs the *.exe the program just start to work, I mean view the interface and ready to work. But there is no installation.

Check the what are inside the folder, found large number of jar files. I know that jar include set of Java classes. My question how those files are execute through the *.exe file.

The most important thing I found is that, no need to install Java either on the machine. No need any related application to install either.

So, how it works. Should exe virtually connect those jar files or anything else is happened there?
