I have had good luck with just using cotton thread and tying it that way that I'd like it. I know a lot of people use super glue but I prefer the thread given that you can just remove it once that plant has attached itself to the driftwood/pot/etc.
I think until the plant fills in it would like a bit silly having a node of java fern sticking out the back of the pot. Just bury the pot deep enough that the hole isn't exposed.
