Java API to read a file diff from CVS repository

[sumit anand kumar]

Hi All,

In my current requirement i have a legacy txt file that contains lots of data , each record per row. The file is checked in at a cvs repository
A legacy system keeps on updating it (adding/deleting) from time to time.

I am writing a code that creates a replica of this legacy txt file in Oracle database.
So i need to write a code in java that creates a sync between my table and the legacy txt file.
My initial thought is to get hold of a cvs api that reads a diff of this legacy file in repository to a local copy and identified which records are added/modified/deleted from the file.
Based on that i will update my database. This will be a time triggered process.

Any thoughts or suggestions? Any standard java api i can use?

I don't think you'll find a "cvs api" to get file diffs. The CVS client program uses the "diff" program in accordance with the ancient and honorable Unix tradition that it's better to glue together simple specialized programs than to write one monster do-all program.

Eclipse's built-in comparision utility on the other hand, I'm not so sure about. Since Eclipse is portable, I would expect that someone probably found (or created) a version of diff written in Java.

Since Eclipse is open-source, I'd recommend looking through the Team/CVS source code and documentation. Your best bet is probably to find the interfaces that it uses and create a small plug-in that will run the internal diff process according to your specific needs.
