i'm trying to get rmi to send a file across the network, just using the rmi method call. though i still havent found a way i can store the file as a single object and pass it as a variable.

files wont be particularly big, 100k max

does anyone know how to do it?
 
Haven't worked with RMI so I wouldn't know a better way. But to put a file in a variable you should probably use a "java.io.ByteArrayOutputStream". Simply read the file you want to send and store it in one of those ByteArrayOutputStream. It will be a copy of the file as an array of bytes. You can then call it's "toByteArray()" method that will return the byte array and send that over RMI.

To reread the file on hte server, create a "java.io.ByteArrayInputStream" with that array and it will be as if you are reading from the file.

Hope it helps.
