Java: send more than one image file from client to server using socket

[vinitvikash]

I want to send more than one image file from client to server for this I write the code in my application, but it will send only one image. In client application one frame is there and in server application also there is a frame to start/stop the server.

One more problem is there when Client application send the image file then this image file shown on server computer but when I try to open this image file then nothing is there but when I close server application(server frame) then I am able to see the image.

code:

client site:

public void sendPhotoToServer(String str){ // str is image location
    try {
        InputStream input = new FileInputStream(str);
        byte[] buffer=new byte[1024];
        int readData;
        while((readData=input.read(buffer))!=-1){
        dos.write(buffer,0,readData); // dos is DataOutputStream
        }
    } catch (FileNotFoundException e) {

    } catch (IOException e) {

    }       
}

In server side this code is running into thread:

public void run() {
while (true) {
            try {
                byte[] buffer = new byte[8192];
                fis = new FileOutputStream("C:\\"+(s1++)+".jpg"); // fis is FileOutputStream
                while ((count = in.read(buffer)) > 0){ //count is a integer and 'in' is InputStream
                fis.write(buffer, 0, count); 
                fis.flush();    
                }
                } catch (Exception e) {}
}
}

Problem:

only 1st image is copying which is send by the client.
I am able to see this Image only when I close the server application.
no exception is there and i call sendPhotoToServer method in other class consecutively to send all the image file as:

if (photoSourcePath != null) {
                            clientClass.sendPhotoToServer(photoSourcePath+"\\"+rowData.get(5));
                        }
