Why does not java support raw sockets?

800670Dec 27 2010 — edited Jan 2 2011
Java does not have support for raw sockets, that means it cannot receive the packet header, just the payload data.
But the header data of an ICMP packet consists of 20 bytes, and you can still write single bytes in Java, so why isn´t is possible to write a header for an ICMP packet in Java?

Can someone explain how it all works?

Thanks!
