Connection between Java and MySql

I am trying to make a connection between Java and my data base. I am using Eclipse and xampp. I am almost convinced that I have good config of Eclipse and xampp, but maybe I missed something. I searched a lot on the Internet, but I have not found the solution.
My error are:
SQLException: Could not create a connection to database server. Attempted to reconnect 3 times. Giving up.
SQLState: 08001
VendorError: 0
Xampp -
Xampp config
Eclipse -
I have jar files in the workspace folder.
Eclipse config
phpmyadmin -
I do not need a password to log into localhost/phpmyadmin and I have only one record in DB.
Code
import java.sql.Statement;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
public class JDBC2 {
static String daneZBazy;
static String polaczenieURL = "jdbc:mysql://localhost:3306/heroes.db?
autoReconnect=true&useSSL=false";
static String login = "root";
static String password = "root";
public static void main(String[] args) {
// Question to DB
String query = "Select * FROM heroestab";
Connection conn = null;
try {
// Connection parameters
conn = DriverManager.getConnection(polaczenieURL, login, password);
// MySQL Driver
Class.forName("com.mysql.jdbc.Driver");
// Start question to DB
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery(query);
while (rs.next()) {
wyswietlDaneZBazy(rs);
}
conn.close();
}
//throws exception
catch (ClassNotFoundException wyjatek) {
System.out.println("Driver error");
}
catch (SQLException wyjatek) {
wyjatek.printStackTrace();
System.out.println("Login problem. Check, username, password, DB name, IP adress");
System.out.println("SQLException: " + wyjatek.getMessage());
System.out.println("SQLState: " + wyjatek.getSQLState());
System.out.println("VendorError: " + wyjatek.getErrorCode());
}
}
static void wyswietlDaneZBazy(ResultSet rs) {
try {
daneZBazy = rs.getString(1);
System.out.println("\n" + daneZBazy + " ");
daneZBazy = rs.getString(2);
System.out.println(daneZBazy + " ");
daneZBazy = rs.getString(3);
System.out.println(daneZBazy);
} catch (SQLException e) {
e.printStackTrace();
}
}
}

Please verify that both the username and password are correct.
I need the full stack trace from:
wyjatek.printStackTrace();
If the username (root) and password are incorrect, you will see the below line in your stacktrace:
Access denied for user 'root'#'localhost' (using password: YES)
If I remember correctly, with default xampp config, you can try this:
user: root
password: [blank]
static String login = "root";
static String password = "";

I can see my databases useing cmd:
C:\xampp\mysql\bin > mysql -u root -p
Enter
show databases ; and then I can see all databases which I have on localhost. When i
chose heroes and I can select * from heroes ;
Picture:

Login success on FTP over explicit SSL/TLS but unable to browse the files

I have been asked to make the secure FTP Server connection. FTP over explicit TLS/SSL. In order to achieve this, I have added a below line in the existing implementation. This is my FTPClient lib - it.sauronsoftware.ftp4j - version 1.6.1
ftpClient.setSecurity(FTPClient.SECURITY_FTPES);
// Existing code
ftpClient.setConnector(new HTTPTunnelConnector(proxyHost, proxyPort));
ftpClient.connect(getFtpHost(), getFtpPort());
ftpClient.login(getUsername(), getPassword());
ftpClient.setAutoNoopTimeout(30000);
When I deployed the code on JBOSS 5.1, I am getting successful connection, but I am unable to list the files in the root directory. we only have permission to access the root directory.
On the other hand, I have written a standalone client (java main program) - through which I can print the files present at FTP location, by this way I have ensured the secure connection and the files availability at FTP location. Here, I have used the
My problem is, when I make a secure connection through the deployed application I am getting the unable to locate any files at remote location. ie: FTPFiles.length is 0
Any help would be much appreciated, thank you!
Adding few more logs and info,
Normal Flow without FTPES security parameter added (current Implementation)
printing ftpClient.serverStatus()
msg: Status of 'FTP Service'
msg: Connected from ec2-xyz
msg: Logged in as <user>
msg: TYPE: BINARY, STRUcture: File, Mode: Stream
msg: Total bytes transferred for session: 10511
msg: No data connection

printing ftpClient.serverStatus() With FTPES added
msg: Status of 'FTP Service'
msg: Connected from ec2-xyz
msg: Logged in as <user>
msg: TYPE: ASCII, STRUcture: File, Mode: Stream
msg: No data connection
msg: End of status
Few questions which I need to know answers (may be that give a lead to fix):
Here, TYPE: BINARY is changed to ASCII and can someone tell how to modify back to BINARY? Note tehre is no explicit setting made, got changed post FTPES set
Is this issue related to proxy / port. if so - I wont be able to provide those information.
As of now, I am testing with same proxy used which is used in the application.
Is there any certificates to be imported to get files viewed / downloaded.
Found this on net which is exactly same as my issue, http://www.proftpd.org/docs/howto/TLS.html ( search for -"I can login using FTPS, but I cannot see any directories. Why not?") but I need to explain my third party to make the required change... what should I tell?

}

Finally, I am able to make the secure connection and able to download the latest files from FTP server using FTPES (FTP over explicit TLS/SSL).
I have made only 2 line code changes (below), in the actual implementation. earlier it was having the list() method to get the files from FTP server, and its return type is FTPFile[]
This is the code changes which I made, and other line of codes are modified / removed.
ftpClient.setSecurity(FTPClient.SECURITY_FTPES);
// get the FTP connection
String[] fileNames = ftpClient.listNames();
// Exisitng implementation
FTPFile[] ftpFiles = ftpClient.list("*.zip");
// after that there is an implementation for getting the latest files using the Comparator<FTPFile>
There was an issue with the LIST command's output, ie: LIST *.zip is not giving the correct output (I guess)

what is 'proxy.mycompany1.local'

I just started working in Java networking protocols. I am trying to connect to the internet using my proxy server. When I see the post at 'https://www.tutorialspoint.com/javaexamples/net_poxy.htm', they set the http.proxyHost property to 'proxy.mycompany1.local'. I know I can set this to my proxy server IP, but I am curious to know why my program still works, even though I set it to some random string like "abcd".
A. What does 'proxy.mycompany1.local" stand for?
B. How come my program works, even though I set the http.proxyHost" to "abcd"?
Following is my working program:
import java.net.HttpURLConnection;
import java.net.InetSocketAddress;
import java.net.Proxy;
import java.net.ProxySelector;
import java.net.URI;
import java.net.URL;
public class TestProxy {
public static void main(String s[]) throws Exception {
try {
System.setProperty("http.proxyHost", "abcd");
System.setProperty("http.proxyPort", "8080");
URL u = new URL("http://www.google.com");
HttpURLConnection con = (HttpURLConnection) u.openConnection();
System.out.println(con.getResponseCode() + " : " + con.getResponseMessage());
} catch (Exception e) {
e.printStackTrace();
System.out.println(false);
}
Proxy proxy = (Proxy) ProxySelector.getDefault().select(new URI("http://www.google.com")).iterator().next();
System.out.println("proxy Type : " + proxy.type());
InetSocketAddress addr = (InetSocketAddress) proxy.address();
if (addr == null) {
System.out.println("No Proxy");
} else {
System.out.println("proxy hostname : " + addr.getHostName());
System.out.println("proxy port : " + addr.getPort());
}
}
}
This is the output:
200 : OK
proxy Type : HTTP
proxy hostname : abcd
proxy port : 8080

First of all, according System Properties tutorial.
Warning: Changing system properties is potentially dangerous and
should be done with discretion. Many system properties are not reread
after start-up and are there for informational purposes. Changing some
properties may have unexpected side-effects.
And my experience say you can get unpleasant issues on your system when you change *.proxyHost properties. So I highly wouldn't recommend you to change system properties for this task.
Much better use something like:
//Proxy instance, proxy ip = 127.0.0.1 with port 8080
Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("127.0.0.1", 8080));
conn = new URL(urlString).openConnection(proxy);
and authorisation on proxy:
Authenticator authenticator = new Authenticator() {
#Override
public PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("user",
"mypassword".toCharArray());
}
};
Authenticator.setDefault(authenticator);
Now return to main questions:
A. 'proxy.mycompany1.local" is just example. You can use any hostname
B. Class URL uses java.net.PlainSocketImpl class via Socket. It tries to resolve proxy hostname 'abcd', swallow error and go to google directly. Just try to play with this code:
import java.net.*;
import java.io.*;
public class RequestURI {
public static void main(String[] args) {
int port = 8181;
long startTime = System.currentTimeMillis();
try {
// System.getProperties().setProperty("http.proxyHost", "abcd");
// System.getProperties().setProperty("http.proxyPort", Integer.toString(port));
URL url = new URL("http://google.com");
HttpURLConnection uc = (HttpURLConnection) url.openConnection();
int resp = uc.getResponseCode();
if (resp != 200) {
throw new RuntimeException("Failed: Fragment is being passed as part of the RequestURI");
}
} catch (IOException e) {
e.printStackTrace();
}
System.out.println("Run time in ms ="+ (System.currentTimeMillis() - startTime));
}
}
You can see run time is bigger when you uncomment section with setProperty. Unsuccessful attempt to resolve hostname increases execution time.

First of all, proxy.mycompany1.local is just a host name, it is a sample, it is nothing special.
I tried your code in a non proxied network, and it worked as you described. I guess that url.openConnection() method ignores proxy settings, because if you manage your own proxy and use url.openConnection(proxy), then it fails with a java.net.UnknownHostException.
Here you are with a piece of code that fails:
SocketAddress addr = new InetSocketAddress("abcd", 8080);
Proxy proxy = new Proxy(Proxy.Type.HTTP, addr);
URL url = new URL("http://google.com");
URLConnection conn = url.openConnection(proxy);
InputStream in = conn.getInputStream();
in.close();

Motivation
I stumbled across this question and answers while investigating the error in question java.io.IOException: The socket is EOF. Because changing the code to use some other SSH Java library is not immediately possible in my case and the stated explanation by #a3.14_Infinity was not detailed enough for me, I'd like to add my take on it.
java.io.IOException: The socket is EOF - Why?
Because this exception is not very helpful, I first tried Wireshark to see what's going on over the wire, but to no avail. So I configured the sshd_config (OpenSSH 6.9) to log on DEBUG3 level and got the answer in the /var/log/auth.log file of my test machine. It stated a fatal error while trying to negotiate the key exchange algorithm with the SSH client (the Java SSH library).
Because the SSH server and client could not agree on a mutual key exchange algorithm the OpenSSH server terminates the connection to the client. In consequence, the Java SSH library code throws the exception.
But why does it happen?
The sshtools.j2ssh (sshtools : j2ssh-core : 0.2.9) library code is pretty old and discontinued. Starting with OpenSSH 6.7 (released October, 2014) default ciphers and MAC have been altered to remove unsafe algorithms which includes the blowfish-cbc cipher. And with OpenSSH 6.9 (released June, 2015) the support for the 1024-bit diffie-hellman-group1-sha1 key exchange is disabled by default.
When you still use the prehistoric SSH Tools j2ssh library (God forbid) connecting to a newer OpenSSH server you will get the described error. The library code only offers the diffie-hellman-group1-sha1 key exchange algorithm to the OpenSSH server which it does not support by default. Thus, a secure connection cannot be established.
Cannot change the code?
If moving to another Java SSH library is not immediately possible (my case) then you can re-enable the disabled diffie-hellman-group1-sha1 key exchange algorithm in the OpenSSH's server config file sshd_config. For example like this.
Ciphers aes128-ctr,aes192-ctr,aes256-ctr,aes128-gcm#openssh.com,aes256-gcm#openssh.com,chacha20-poly1305#openssh.com,blowfish-cbc
KexAlgorithms diffie-hellman-group1-sha1,diffie-hellman-group-exchange-sha1,curve25519-sha256#libssh.org,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group-exchange-sha256,diffie-hellman-group14-sha1
But let me be clear on this. The diffie-hellman-group1-sha1 key exchange algorithm as well as the blowfish-cbc cipher are turned off by default because they are insecure. Reenabling them should only be a temporary measure until you can replace this obsolete Java SSH library.
Finally, I like to point out that the suggested Java Secure Channel (JSch) library in other answers is discontinued. So, you might want to consider sshj or even ssh2j-maverick instead.
Edit: I was wrong, the Java Secure Channel JSch library is alive (JSCH 0.1.54 was released on 2016-09-03 on MavenCentral) and certainly worth your consideration. Alternatively, you may want to consider also sshj or ssh2j-maverick.
Addendum: Migration
To keep the migration effort for the sshtools.j2ssh (sshtools : j2ssh-core : 0.2.9) library minimal I looked at the commercial legacy SSH client library from SSHTOOLS (version 1.7.1). This allowed to keep the existing library integration code with few minor changes regarding library API and exception handling. Thus, if you do not want to restart from scratch then biting the bullet and sticking with SSHTOOLS is probably your best option. Finally, to gauge the migration effort I first replaced the library with SSHTOOLS' open source library ssh2j-maverick which almost has the same API as its latest commercial version (version 1.7.1).

This error ("The Transport Protocol thread failed. java.io.IOException: The socket is EOF”) occurs when j2ssh.jar file is not compatible with current SSH version of SFTP server.
You can try using Java Secure Channel (JSch) from here.

found a simple solution on the OS:
comment out the Cipher line in /etc/ssh/sshd_config
and run service sshd restart

Do i have to configure any thing in jndi.properties config file in glassfish server. Currently the jndi.properties final has
java.naming.factory.initial=com.sun.enterprise.naming.impl.SerialInitContextFactory

The URL you provided has a section "Creating JMS Administered Objects". You should follow those steps to properly configure your testing environment.
The tutorial teaches you how to configure that using a web interface, but you should be able to find the config files on the server to apply the same data to your Eclipse environment later.
Glassfish has a similar web console. You should be able to create Connection Factory in a similar way as the tutorial teaches.
