The API to for calling C code is called JNI.

If you just want to start a program, you can do that using the ProcessBuilder class or the Runtime.exec method.

You can call a C program from a Java class using the J2EE Connector Architecture API.

I dont want J2EE enterprise Connnector architecture.
My simple requirement is : I would like to get some fuctionality, which is there in C program.

Thank in advance.
will appreciate for your replies.

If neither of the suggestions I made are practical (why not?) you'll have a hard time getting this to work.

Ok. However, you asked a question and I gave you an answer. You can get the functionality of the C program with the JCA API. (See link above more info)

Good luck!
