Creating a Hard Link in java

Question

Currently I use 'ln' command via Runtime.exec(). It works fine. The only problem is that in order to do this fork, we need twice the heap space of the application. My app is a 64 bit app with heap size around 10Gigs and thus its runs out of swap space. I couldn't find any configuration that could fix this.

I also want not to use JNI for the same. Also I had heard somewhere that this facility will soon be provided in java 7.

Answer 1

It’s easy in Java 7 using createLink:

Files.createLink(Paths.get("newlink"), Paths.get("existing"));
