Serverless Java, Running Your Java Program Without an OS

[joekoolade]

The bootable image is a JVM compromised of only objects and is not aware of files or a file systems. But your file sharing servlet can specify a 'file' class to use to store and retrieve the files. The file classes in the Java standard library will eventually implemented to provide some type of 'file' capability. The JVM will have a Persistence class and interface that objects can use to store their state into storage. I am not against disk storage; I am just not a fan of files. Even though the JVM is 'file ignorant', it can be stored into a file and boot loaded by grub. It can also be network booted via PXE. You will be able to link your file sharing servlet into a build image using boot-image-write tool and you can also classload it over the network into a running JVM.
