Random access file help

[Lupine]

basically I need to write out (Unicode) and
read in (Unicode) char, boolean, and byte (java 1.1)
from files in a .jar
I'm looking at: implements DataInput,DataOutput

is this possible?

how do I specify the .jar?

how do I "seek" within the .jar for a specific file?

once I have the file, lets assume I know the format,
how do I read in the info I want?

What requirements(methods) of DataInput and DataOutput do I have
to satisfy?

how do I overwrite the 73rd byte of "map.txt", or do
I have to rewrite the whole file?

should I use comma seprated or tab delimited files?

I am reading books in the meantime but
I don't see much help yet.

thanks for any help.
