Failed to connect to JMX while started to use the JMX authentication on Linux

My JMX client failed to connect to JMX server while I have started to use the JMX authentication.
I use Java 8 and Centos6.
I have configured the following settings:
JAVA_OPTS="${JAVA_OPTS} -Dcom.sun.management.jmxremote.authenticate=true -Dcom.sun.management.jmxremote.password.file=<path to password file> -Dcom.sun.management.jmxremote.access.file=<path to access file>"
Unfortunately my JMX client failed to connect to JMX server with the following exception:
java.io.IOException: Failed to retrieve RMIServer stub: javax.naming.ServiceUnavailableException [Root exception is java.rmi.ConnectException: Connection refused to host: localhost; nested exception is:
java.net.ConnectException: Connection refused]

To solve it I read carefully the documentation:
http://docs.oracle.com/javase/7/docs/technotes/guides/management/agent.html#gdeup
The following comment about the password file is very important:
You must ensure that only the owner has read and write permissions on this file, since it contains the passwords in clear text. For security reasons, the system checks that the file is only readable by the owner and exits with an error if it is not.
I set read permission to a user and my client successfully connects to the JMX server:
chmod 400 <path to password file>

Web Service Connection Refused

I'm trying to connect to my web service, the trouble is my connection is getting refused. I am running WAMP on a server that the web service is running on and I am running Apache Tomcat8 on eclipse. Here is the stack trace:

Here is the client as well:
import java.util.*;
import java.io.*;
import javax.xml.rpc.ServiceException;
public class message {
public static void main(String[] args) throws IOException
{
Scanner in = new Scanner(System.in);
System.out.println("Enter a word: ");
String a = in.next();
WebserviceServiceLocator locator = new WebserviceServiceLocator();
WebserviceSoapBindingStub stub;
try {
stub = (WebserviceSoapBindingStub)locator.getwebservice();
System.out.println(stub.echo(a));
} catch (ServiceException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
Echo just returns what you put into it.

I had a similar error when I was working with webservices deployed on glassfish and it was because I previously killed the glassfish process, thus the server stopped running. That's why the conncetion between the client and the webservice couldn't be established. Check if your Tomcat server is still running.

Connection Exception between systems

This question has been asked many times and I followed the solutions but didn't work.
I am getting
java.rmi.ConnectException: Connection refused to host: 10.155.1.232; nested exception is:
java.net.ConnectException: Connection timed out: connect
tried to telnet from my system to 10.155.1.232 1099 port..I am able to telnet means there is no port issue
also tried to telnet viceversa on port 8090 of my tomcat,again its working
There is no firewall on my system.
Do I need to check if the rmi registry is already running on 10.155.1.232?
How to check if rmiregistry is working in windows system from cmd?
So Please guide me what can be the issue

If you can see rmiregistry.exe from Task Manager you are fine. But I think you are missing security policy.
Look it up: rmi run tutorial and let me know?

SSLException - Axis Connection shutdown on large request

Since this week, I'm unable to get large responses from an Axis 1.4 Web service. My Web Service Client use to work well before this week. But now, when I fire a large request by using the stub, it ends with a "Connection has been shutdown [...] Connection reset by peer : socket write error".
Then I started to send smaller requests with the same stub method and I works fine... I tried to add a timeout to my stub "stub.setTimeout(10000)" but it didn't work. I've also set a timeout when I create SSL certificat like:
SSLSocket socket = (SSLSocket)factory.createSocket(host, port);
socket.setSoTimeout(10000);
Did not work too...
Here is the first part of the complete error stacktrace...

Does someone have a clue or knows how can I solve that problem?
Oh... I'm using:
Eclipse - Tomcat 6 - Java 6 - Axis 1.4
Thank you very much for taking time to answer!!!

Going by the stacktrace, as Jim said ,it does not involve the MySql connector. Its tomcat closing the socket on its end for some reason while serving error.jsp to the client.You should check the server logs to zero in on the error.
