java6 sslv3_Client requested protocol SSLv3 not enabled or not supported (IBM JDK 6.0SR10)

The exception occurs when the client and server SSL protocol settings do not match.

The following client sample code works with server side configured supporting TLSv1.2 protocol:

String response = "";

URL url = new URL("https://localhost:9043/myservlet);

final SSLContext ctx = SSLContext.getInstance("TLSv1.2");

ctx.init(null, null, null);

// final String protoccol = ctx.getProtocol();

HttpsURLConnection.setDefaultSSLSocketFactory(ctx.getSocketFactory());

final HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();

conn.setReadTimeout(15000);

conn.setConnectTimeout(15000);

conn.setRequestMethod("POST");

conn.setDoInput(true);

conn.setDoOutput(true);

final OutputStream os = conn.getOutputStream();

final BufferedWriter writer =

new BufferedWriter(new OutputStreamWriter(os, "UTF-8"));

writer.write(......);

writer.flush();

writer.close();

os.close();

final int responseCode = conn.getResponseCode();

if (responseCode == HttpsURLConnection.HTTP_OK) {

String line;

final BufferedReader br =

new BufferedReader(new InputStreamReader(conn.getInputStream()));

while ((line = br.readLine()) != null) {

response += line;

}

}

System.out.println("response: " + response);
