I’ve been using a portable version of Netbeans for a long time on my USB. In some locations it is hard to get administrator permissions to install software. I’ve done it before installing on a machine, copying the files and then using parameters to start the application via PStart. it has worked fine as Netbeans is designed with portability in mind, but still might be a hassle for newbies.
I also have many application using Portable Apps, which does exactly that, remove the hassle up installation and updates. I was never able to find, or create for that matter, a proper Portable Apps for Netbeans but it seems someone did! Netbeans Portable is available and already on it’s 8.0 version!
Just need to place a copy of the JDK were specified and it works wonders!
