Sending int via socket from Java to C - strange results

I have a simple server written in Java, that just sends an Integer to a connected client. I have a client written in C, that connects to the server and prints out the received Integer.

My problem is that the result varies. About half of the times executing the client I get the correct result (234), but other times I get 8323072.

This is the server:

class TCPServer {
  public static void main(String args[]) throws Exception {
     ServerSocket welcomeSocket = new ServerSocket(6789);

     while(true)
     {
        Socket connectionSocket = welcomeSocket.accept();
        System.out.println("welcomeSocket.accept() called");
        DataInputStream inFromClient = new DataInputStream(connectionSocket.getInputStream());
        DataOutputStream outToClient = new DataOutputStream(connectionSocket.getOutputStream());

        outToClient.writeInt(234);
     }
  }

}

And this is the client:

int main(int argc, char *argv[])
{
    if(argc != 4){
        printUsage();
        return;
    }

    char* serverIP = argv[1];
    char* serverPortC = argv[2];
    char* integerToSendC = argv[3];

    int serverPort = atoi(serverPortC);
    int integerToSend = atoi(integerToSendC);

    int socketDesc = socket(AF_INET, SOCK_STREAM, 0);

    if(socketDesc < 0) {
        printf("Error when creating socket\n");
        return;
    } 

    struct sockaddr_in serverAddr;
    serverAddr.sin_family = AF_INET;
    serverAddr.sin_port = htons(serverPort);
    inet_pton(AF_INET, serverIP, &serverAddr.sin_addr);

    int connection = connect(socketDesc, (struct sockaddr*) &serverAddr, sizeof serverAddr);

    if(connection < 0) {
        printf("Error when establishing connection\n");
        return;
    }

    char intBuffer[4];

    if(recv(socketDesc, intBuffer, sizeof intBuffer, 0) == -1){
        printf("Error while receiving Integer\n");
    }

    int receivedInt = ntohl(*((int *) &intBuffer));

    printf("Received int: %d\n", receivedInt);

    close(socketDesc);
}

Thanks in advance for any help!

Edit: So in the end I did something like this, just for anybody who has the same problem:

while(receivedBytes < 4){
    int readBytes = read(receiverSocket, &intBuffer, (sizeof intBuffer) - receivedBytes, receivedBytes);
    receivedInteger += (intBuffer << (8*receivedBytes));
    receivedBytes += readBytes;
}
