Java Security

import java.net.*;

import javax.net.ssl.*;

public class ReadHttpsURL1 {
static final int HTTPS_PORT = 443;

public static void main(String argv[]) throws Exception {
if (argv.length != 1) {
System.out.println("Usage: java ReadHttpsURL1 ");
System.exit(0);
}

// Get a Socket factory
SocketFactory factory = SSLSocketFactory.getDefault();

// Get Socket from factory
Socket socket = factory.createSocket(argv[0], HTTPS_PORT);

BufferedWriter out = new BufferedWriter(new
OutputStreamWriter(socket.getOutputStream()));
BufferedReader in = new BufferedReader(
new InputStreamReader(socket.getInputStream()));
out.write("GET / HTTP/1.0\n\n");
out.flush();

String line;
StringBuffer sb = new StringBuffer();
while((line = in.readLine()) != null) {
sb.append(line);
}
out.close();
in.close();
System.out.println(sb.toString());
}
}

I get the following exception when I ran the class in Red Hat Linux ES 2.1

Exception in thread "main" java.net.SocketException: Default SSL context init failed: Algorithm SunX509 not available
at javax.net.ssl.DefaultSSLSocketFactory.createSocket(DashoA6275)

I did not encounter any problems in compiling the file
