How can C socket talk to Java Socket?

Question

Hello, all
I am writing a gateway program (written in Java) that accepts request from clients (written in C)
My problem is that "Java end" cannot receive an EOF from "C end", thus it is always waiting for it.....
C End
error = 0;
while (error < strlen(request))
         error += write(fd, request, strlen(request));
         if (error < 0)
                 perror("write");
                 return -1;
} /* write */Java End
int c;
while ((c = input.read()) != -1)
         System.out.printf("%c", (char)c);
         request.append((char)c);
System.out.println(request);Could anybody tell me solve this problem?
Thanks!!

The receiver will get an EOF after the sender closes the socket. (Or half closes it; see the shutdown() system call.)
If you want to keep the connection open, you need to use some other end-of-request terminator. Such as \n if the request never has embedded newlines.
Btw, the "while(error < ...)" loop in the sender isn't right. It will make more sense if you add "request += error;" to the loop.
