JMeter: Remote host closed connection during handshake

I am running a JMeter test with "Java Request" sampler which performs POST request to HTTPS service which uses TLS v1.2. The request fails with

JMeter used to work with this server when it used TLS v1.1. Is there a setting in JMeter properties which can set the applicable protocol.
The JMeter version is 2.13, Java version is 1.7.

This is an SSL error and can mean several things. Make sure you have TLS 1.2 enabled in your application (JVM argument?)(-Dhttps.protocols=TLSv1.2). You can use openssl to check the connection and see if you are getting back a certificate. If you are then check your keystore and make sure you have the correct certificate. You may not be authorized to access that server.

Jmeter Error While Recording

I am getting below error in browser while recording an application in JMeter.

I am giving the address as Localhost and port as 8080.
I am using JMeter 2.11 and it is working fine for all other applications.
Only while recording this particular application I am getting above error.

Your stack trace says in the first line:
org.apache.http.conn.HttpHostConnectException: Connection to http://access.xyz.com refused
In your description after the stack trace you said the service was on localhost port 8080. The problem is you are requesting a URL with no service behind it. Change the URL you are querying to:
http://localhost:8080
or if you've hacked your HOSTS file to have access.xyz.com resolve to localhost, then you need to specify the port number in your URL like this:
http://access.xyz.com:8080
Without the :8080, the protocol http uses the default port of 80. Similarly, the default port for the protocol https (SSL) is 443. If you use anything other than the default port, you have to explicitly set the port in the URL.

Self-signed java applet raise error "Permission denied" while send mail via SMTP

I have self-signed java applet. This applet should send email message every time, when raise unhandled exception.
My applet crashed with exception in that moment, when I am trying to send mail. For sending email I usung Java Mail API (javax.mail).
Java console shows follow text:
javax.mail.MessagingException: Could not connect to SMTP host: host.ru, port: 25;
nested exception is:

Please, explain me, what I am doing wrong?

It's possible that you are executing your code from eclipse with java 1.6 version, and when you use this code as an applet java plug-in is executing on java 1.7?
If this is the case you can add this parameter to your applet call:
<PARAM name="java_arguments" value="-Djava.net.preferIPv4Stack=true">
If you are using deployJava.js:
<script src="https://www.java.com/js/deployJava.js"></script>
<script>
var attributes = {...} ;
var version = '1.7';
var parameters = { java_arguments : '-Djava.net.preferIPv4Stack=true'...} ;
deployJava.runApplet(attributes, parameters, version);
</script>
Keep in mind that if you use java mail api the SMTP Server must be located on the same machine as the web server (http://www.oracle.com/technetwork/java/faq-135477.html#applets)
Hope this helps,

java.rmi.ConnectException: Connection refused to host

After a hard work, I have set up Java RMI tunnelling using apache as http
server. Everything is fine and Works like a charm at my office LAN.But when I installed at client's place, I am getting some exception.The RMI System works only on his server.
When I tried from other clients' pcs I get the following.
Can you guys help me solve this?

I am running files from roseindia rmi
there is mistake rmicregistry, one have to use rmiregistry:
I changed ip to localhost, how to run on special port number I don't know this moment
one has to use rmiregistry
not rmicregistry
so:
move to folder where does your class files take seat.
type : rmiregistry
then open 2 new command prompts move to same folder where classes seat and use one to run server and another to client.

RMI servers have the nasty habit to pass new port numbers to clients to handle the client communication to a particular Remote object. If this port number is blocked by the firewall, you would get an exception like that.
Make sure you register all Remote objects with the same port number. RMI will then multiplex the client calls for you.

after my research, the solution is:
System.setProperty("java.rmi.server.hostname", IP);
before you register the service on server side. following is an example, hope it might help you!
public static void main(String[] args) throws MalformedURLException, RemoteException, AlreadyBoundException {
RmiServer server=new RmiServer();
System.setProperty("java.rmi.server.hostname", 指定IP);
LocateRegistry.createRegistry(8808);
Naming.rebind("//10.10.116.74:8808/SAMPLE-SERVER", server);
}

javax.net.ssl.SSLHandshakeException: certificate expired - Local or Remote?

I am receiving the following exception while trying to make an SSL connection to a web service. Does this error mean my local keystore/certificate is expired, or is it that I cannot trust the remote server because it has the expired certificate?
javax.net.ssl.SSLHandshakeException: certificate expired

Remote certificate expired, webservice's appserver needs to update its cert.
