I just started making my own virtual machine using VM player and ubunto as my OS and i see lots of discussions debating how to run java portably etc and was wondering if you could use a virtual machine on any computer, with your external hardrive or usb to use any java application???
why hasn't anyone thought of this.

Because practically all Virtual Machines (but QEMU) require admin privileges. And Java Portable works with a select few apps, but not all of them.
The problem is mainly with Firefox, since it stores it's Java location settings in HKLM section of the registry, which again, requires admin privileges to modify. With Eclipse based apps, you could just pass a -vm switch, which works nicely.
