Can't send large files over socket in Java

[Chillo]

I got working server and client applications, they work perfect while sending small files, but when I try to send for example movie file that is 700mb over socket it gives me \[code\]Exception in thread "AWT-EventQueue-0" java.lang.OutOfMemoryError: Java heap space\[/code\]I searched the internet and found some tutorials on sending large files, but couldn't quite understand them, but I think my porblem is in writing file.This is the code that server uses to write my file:\[code\]output = new FileOutputStream(directory + "/" + fileName); long size = clientData.readLong(); byte[] buffer = new byte[1024]; while (size > 0 && (bytesRead = clientData.read(buffer, 0, (int) Math.min(buffer.length, size))) != -1) { output.write(buffer, 0, bytesRead); size -= bytesRead; } output.close();\[/code\]And here is the code that my client uses to send a file:\[code\]byte[] fileLength = new byte[(int) file.length()]; FileInputStream fis = new FileInputStream(file); BufferedInputStream bis = new BufferedInputStream(fis); DataInputStream dis = new DataInputStream(bis); dis.readFully(fileLength, 0, fileLength.length); OutputStream os = socket.getOutputStream(); //Sending size of file. DataOutputStream dos = new DataOutputStream(os); dos.writeLong(fileLength.length); dos.write(fileLength, 0, fileLength.length); dos.flush(); socket.close(); \[/code\]
