Using revision control (RCS) with java

Hi,

My java program manage small database which is saved in text files.

I want to use RCS (Revision Control System) for this database - and do it using java.

How do I read, save and append files using RCS with java ?

One option is every time i want to read it - send tread or system command like
Runtime.getRuntime().exec("co -l my_file ")

but it is messy,

note that the rcs is not meant to save the java code itself , but to be used in the code itself somehow. But when I google java and rcs - i found only how to revision the java code .

Here
