I'm trying to download some content using the URL class with a given link that comes from the server.
My code to download is it:
URL url = new URL(downloadUrl);
InputStream stream = url.openStream();
byte[] content = new byte[stream.available()];
stream.read(content);
stream.close();
But when running I got the following exception:
java.io.IOException: SSL handshake failure: Failure in SSL library, usually a protocol error
error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol (external/openssl/ssl/s23_clnt.c:604 0xaf076228:0x00000000)
at org.apache.harmony.xnet.provider.jsse.OpenSSLSocketImpl.nativeconnect(Native Method)
...
The link I was using is something like:
https://contentserver.com/d/761/34/215656/5de1a41ea3bc9c81978af95ed19b03286f64d9a3
I know if I enter it on browser it donwload an File, I want download the same file throught Java.
Thanks
Code to read data from the https url in java
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.IOException;
import java.net.*;
import java.security.Security;
import java.util.Properties;
public class UseHttps {
public static void main(String argv[]) {
String fullURL = "https://fortress.wa.gov/lni/bbip/detail.aspx?License=SIBLUCL004C5";
try {
URL page = new URL(fullURL); // Process the URL far enough to find the right handler
URLConnection urlc = page.openConnection();
urlc.setUseCaches(false); // Don't look at possibly cached data
System.out.println("Content-type = " + urlc.getContentType()); // See what's here
System.out.println("Content-length = " + urlc.getContentLength()); // See how much of it there is
// Read it all and print it out
BufferedReader br = new BufferedReader(new InputStreamReader(urlc.getInputStream()));
String buffer = "";
while (buffer != null) {
try {
System.out.println(buffer);
buffer = br.readLine();
}
catch (IOException ioe) {
ioe.printStackTrace();
break;
}
}
}
catch (MalformedURLException mue) {
System.out.println(fullURL + " is not a URL that can be resolved");
}
catch (IOException ie) {
ie.printStackTrace();
}
}
}
