This JAVA socket program will download webpage (HTML file)
from server to client. Downloaded file will be opened into web browser.
SERVER side program
import java.io.*;
import java.net.*;
public class FTPServer {
public static
void main(String[] args) throws IOException {
//server will start at port number 12345.
ServerSocket servsock = new ServerSocket(12345);
//server will send index1.htm file to client.
ServerSocket servsock = new ServerSocket(12345);
//server will send index1.htm file to client.
File myFile =
new File("D:\\index1.htm");
System.out.println("Waiting for Client Request...");
while (true) {
Socket sock =
servsock.accept();
byte[]
mybytearray = new byte[(int) myFile.length()];
BufferedInputStream bis = new BufferedInputStream(new
FileInputStream(myFile));
bis.read(mybytearray, 0, mybytearray.length);
OutputStream
os = sock.getOutputStream();
os.write(mybytearray, 0, mybytearray.length);
os.flush();
sock.close();
}
}
}
SERVER side Output:
Waiting for Client Request...
CLIENT side program
import java.awt.Desktop;
import java.io.*;
import java.net.*;
public class FTPClient {
public static
void main(String[] argv) throws Exception {
//socket will be created local IP: 127.0.0.1 and port 12345.
Socket sock = new Socket("127.0.0.1", 12345);
byte[]
mybytearray = new byte[1024];
InputStream is
= sock.getInputStream();
FileOutputStream fos = new FileOutputStream("D:\\index2.htm");
BufferedOutputStream bos = new BufferedOutputStream(fos);
int bytesRead =
is.read(mybytearray, 0, mybytearray.length);
bos.write(mybytearray, 0, bytesRead);
System.out.println("File downloaded...");
Following code will open index2.htm file in browser.
String url="D:\\index2.htm";
String url="D:\\index2.htm";
File
htmlFile=new File(url);
Desktop.getDesktop().browse(htmlFile.toURI());
bos.close();
sock.close();
}
}
CLIENT side output:
File downloaded...
