In my experience Java fern is a bit weird. The roots aren't suposed to grow in the soil. They grow on submerged wood. You can tie or rubberband the plant down to the wood. Also, if the plant gets shocked, or the roots get too disturbed, which happens in the time during it's journey from the nursery to the store to your tank, the leaves will stop growing and new leaves will in turn grow right out of the old leaves which may be decomposing at this point. This dosen't look too good usually, so I've let these new growths start for a while, then I've removed the whole original leaves and in turn tied them down. The new leaves will then all grow nicely to length together and they should be easy to grow with pretty low light and without CO2 as poetic irony Brandon has said.

Cannot help you with the Java Fern, but 30 ppm of nitrates is too high. As a general rule, do enough water changes to keep it below 20 ppm. Above this mark and the water is getting toxic to your fish. Once you push up towards 40 ppm, your fish will start to die. Good luck with the Java. I had a bunch in an old tank and I really liked it.
