Just search the forum for "moss wall"
If thats too much work and you don't have too much filtration, you can still just cut up a portion of java moss into real tiny pieces (in a food processor perhaps) rinse the pieces if you can, then dump them in your tank. They'll anchor themselves all over your tank decor and substrate.
Mosses would grow best in a dry start: if you have an extra tank pm me and Ill come back and tell you how.
I actually saw some one else do this on another forum, was quite interesting. With more area where the moss will grow, it does make sense that chooping it up will make it grow in faster.
Moss, if wanted to made into a carpet type plant will do fine in anything because it doesn't really root in the same way other plants do. The most common method is the moss ceramic tiles, or stainless steel mesh with moss sandwiched in between. It will grow in eventually depending on your tank conditions. Moss may grow fast in some tanks but slow in others.
