Sto cercando di fare una connessione SSL con Socket Java.
Ma ho il seguente problema

Scrivo il codice incriminato:

codice:
//Carico il Key Store
			objKeyStore.load(new FileInputStream(certificato_kst), arrpassword);		

			//Carico Trust Store
			objKeyManagerFactory.init(objKeyStore, arrPassword_kst);	

			// Trust Store
			MakeKeyStore objMakeTrustStore = new MakeKeyStore();
			KeyStore objTrustStore = objMakeTrustStore.getKeyStore();

			// Carico il Trust Store
			objTrustStore.load(new FileInputStream(certificato_kst), arrPassword_tru);

			// Trust Manager
			MakeTrustManagerFactory objMakeTrustManagerFactory = new MakeTrustManagerFactory();
			TrustManagerFactory objTrustManagerFactory = objMakeTrustManagerFactory.getTrustManagerFactory();

			objTrustManagerFactory.init(objTrustStore);

			objSSLContext.init(objKeyManagerFactory.getKeyManagers(), objTrustManagerFactory.getTrustManagers(), null);
			objSSLSocketFactory = objSSLContext.getSocketFactory();

			echoSocket =(SSLSocket)objSSLSocketFactory.createSocket("10.16.10.9", 4000);


echoSocket.setSoTimeout(timeout);
			
			alServer          = new PrintWriter(echoSocket.getOutputStream(), true);
			dalServer         = new BufferedReader(new InputStreamReader(echoSocket.getInputStream()));


			response="";
			
						
			/*
			String messaggioDalServer   = "";

			while(messaggioDalServer != null && !messaggioDalServer.trim().equals("")) 
			{
				messaggioDalServer = dalServer.readLine();
				System.out.println(messaggio);
				if(messaggioDalServer != null && !messaggioDalServer.trim().equals(""))
				{
					messaggioDalServer = objBufferedReader.readLine();
				}
			}
			*/
			System.out.println("--- PRIMA DI FARE alServer.print(messaggio) ");
			alServer.print(messaggio);
			System.out.println("--- DOPO alServer.print(messaggio) ");
			alServer.flush();
			System.out.println("--- HO FATTO ANCHE alServer.flush() ");
			char[] b= new char [2000];
			System.out.println(" --- PRIMA DI FARE dalServer.read(b) ---");
			dalServer.read(b);
			System.out.println(" --- DOPO dalServer.read(b) ---");
			for (int i=0;i<b.length;i++)
			{
				System.out.println(" --- Sto nel ciclo ---");
				if (b[i]!=0)response+=b[i]; 
			}
			System.out.println(" --- DOPO IL CICLO ---");
			System.out.println(response);
			// close();
		}
		catch(Exception e)
		{
			System.out.println("Errore Socket");
			e.printStackTrace();
		}

Ecco l'errore:

GRAZIE Anticipatamente

PS. L'errore è scatenato da questa riga: dalServer.read(b);
