Simple utility to test SSL connections (i.e. certificate/trust store configuration) from java applications, use debug flag for lots of information.

SSLTest.java

package uk.co.diffa.ssltest;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.MalformedURLException;
import java.net.URL;

import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLSocketFactory;

public class SSLTest {

  public static void main(String[] args) throws Exception {
		if (args.length == 0) {
			printUsage();
		} else {		
			testConnection(args);
		}
	}

	private static void testConnection(String[] args) throws MalformedURLException, IOException {
		SSLSocketFactory sslsocketfactory = (SSLSocketFactory) SSLSocketFactory.getDefault();
		URL url = new URL(args[0]);
		HttpsURLConnection conn = (HttpsURLConnection)url.openConnection();
		conn.setSSLSocketFactory(sslsocketfactory);
		InputStream inputstream = conn.getInputStream();
		InputStreamReader inputstreamreader = new InputStreamReader(inputstream);
		BufferedReader bufferedreader = new BufferedReader(inputstreamreader);

		String string = null;
		while ((string = bufferedreader.readLine()) != null) {
		    System.out.println("Received " + string);
		}
	}

	private static void printUsage() {
		System.out.println("Usage: java -jar ssltest.jar https://{host}[/uri]");
		System.out.println("-------------------------------------------------");
		System.out.println("You may need some or all of the following settings:");
		System.out.println("-Djavax.net.ssl.keyStoreType={pkcs12|jks}");
		System.out.println("-Djavax.net.ssl.trustStoreType={pkcs12|jks}");
