Exception Occured in the process :java.sql.SQLException: Access denied for user 'root'#'localhost' (using password: YES)"
Thank you for all help, I am very new to this. I am positive the password and username are correct so I am unsure where to go from here. Here is my code for connecting to the database:

In MySQL server administration, users are specified with both allowable hostnames and passwords. If the root user was not set up to include localhsot as a client, it will deny logins on the local machine. See this question and its accepted answer for some details.
Can you try like this
con = DriverManager.getConnection("jdbc:mysql://localhost:3306/test","root","pass");
As getConnection function requires 3 arguments : url+dbname , username , password.
Your password is wrong it seems.
You can try with empty password given below.
String conUrl = "jdbc:mysql://localhost:3306/test; user=root; password=;";

The place I was going wrong was giving the location of the configuration file in java.security file, which is present in C:\Program Files\Java\jre1.8.0_77\lib\security\java.security.
When copying the path of the jaas.config file in Windows the path is given with backward slashes( / ), which should be replaced with forward slashes( \ ).
For example, it should be like login.config.url.1=file:D:/mani/java/sample_jaas.config and not as login.config.url.1=file:D:\mani\java\sample_jaas.config
I guess it will be helpful for someone.
I am trying to make a project on Servlets using JDBC. But there are some persistent errors in the error log like java.lang.Class.forName(Unknown Source), java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source), java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source), java.lang.Thread.run(Unknown Source) etc. How can I solve such errors from happening?
I am using Apache Tomcat v7.0, mySQL Community Server v5.7 and Eclipse IDE.

You need to include multicatch statement for that (same catch for SQLException and ClassNotFoundException)
You can modify your catch statement to this:
catch (ClassNotFoundException | SQLException e)
{
e.printStackTrace();
}
Try this. You can use a multicatch statement wherever you need to catch multiple exceptions.
This exception is thrown whenever a class existed at compile time but not at run time.
Please check that at runtime ur classpath is correct and you are pointing to the library in question (in ur case the mysql connector jar).
This error is produced by launching the jar file in cmd with "G:\Orchid\OrchidFX.jar". When launching the application through IntelliJ everything runs just fine. Also, in File->ProjectStructure we have added sqljdbc4.jar to the library.

I'm using Spring framework to login with twitter into my website, I'm actually learning from this tutorial.
So i followed this question and changed my source accordingly below:
#RequestMapping("/welcome")
#Controller
public class HelloController {
private final String CONSUMER_KEY = "xxxx";
private final String CONSUMER_SECRET = "xxxx";
ConfigurationBuilder confBuilder = new ConfigurationBuilder()
.setOAuthConsumerKey(CONSUMER_KEY)
.setOAuthConsumerSecret(CONSUMER_SECRET);
Configuration configuration = confBuilder.build();
TwitterFactory factory = new TwitterFactory(configuration);
Twitter twitter = factory.getInstance();
#Autowired
private MyAccessToken accestoken;
#RequestMapping(method = RequestMethod.GET)
public String printWelcome(HttpServletResponse response,HttpServletRequest request) {
twitter.setOAuthConsumer(CONSUMER_KEY, CONSUMER_SECRET);
RequestToken requestToken;
try {
String callbackURL = "http://127.0.0.1:8080/cwitter/callback";
System.out.println("callback url is " + callbackURL);
requestToken = twitter.getOAuthRequestToken(callbackURL);
String token = requestToken.getToken();
String tokenSecret = requestToken.getTokenSecret();
accestoken.setTokensecret(tokenSecret);
accestoken.setToken(token);
String authUrl = requestToken.getAuthorizationURL();
request.setAttribute("authUrl", authUrl);
} catch (TwitterException e) {
e.printStackTrace();
}
return "login";
}
#RequestMapping(value = "/{username}/test1",method=RequestMethod.GET)
public String test1(#PathVariable String username,#RequestParam("userdetails") String userDetails,ModelMap model){
System.out.println("test1 " + username + "\t" + userDetails);
model.addAttribute("message", "Spring 3 MVC Hello World");
return "hello";
}
#RequestMapping(value = "/callback",method=RequestMethod.GET)
public String test1(HttpServletRequest request, ModelMap model){
Twitter twitter = (Twitter) request.getSession().getAttribute("twitter");
System.out.println(twitter);
RequestToken requestToken = (RequestToken) request.getSession().getAttribute("requestToken");
String verifier = request.getParameter("oauth_verifier");
Enumeration attrList = request.getSession().getAttributeNames();
while(attrList.hasMoreElements()){
System.out.println(request.getSession().getAttribute((String)attrList.nextElement()));
}
try {
System.out.println(twitter.getOAuthAccessToken(requestToken, verifier));
request.getSession().removeAttribute("requestToken");
// twitter.setOAuthAccessToken(accessToken);
User user = twitter.verifyCredentials();
model.addAttribute("message", user.getName());
} catch (TwitterException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return "hello";
}
}
So, I simply tried to run all my project but it says the following logs:
SEVERE: Servlet.service() for servlet [mvc-dispatcher] in context with path [/cwitter] threw exception [Request processing failed; nested exception is java.lang.IllegalStateException: consumer key/secret pair already set.] with root cause

Please let know, What's wrong here?
Any kind of help would be appreciated!!
I try to connect to mysql database on my Java EE project but i get an error and I do not know where is the problem.
And this is SERVLET, CLASS AND ERRORS
The Java EE Servlet:
package com.hopital.servlet;

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpSession;
import com.hopital.database.Recup_Insert;
import com.hopital.forms.Connections;
#WebServlet("/hopital")
public class hopital extends HttpServlet {
private static final long serialVersionUID = 1L;
public hopital() {
super();
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
//extrait les cookies
Cookie[] cookies= request.getCookies();
if(cookies != null){
for(Cookie cookie: cookies){
if(cookie.getName().equals("login")){
request.setAttribute("login", cookie.getValue());
}
}
}
//session
HttpSession session= request.getSession();
String login= (String) session.getAttribute("login");
request.setAttribute("login", login);
//extrait les chambers
Recup_Insert tableChamber= new Recup_Insert();
request.setAttribute("chambres",tableChamber.recup_chmabre());
this.getServletContext().getRequestDispatcher("/WEB-INF/home.jsp").forward(request,response);
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
//verification de champs

HttpSession session= request.getSession();
session.setAttribute("login", login);
session.setAttribute("pass", pass);
this.getServletContext().getRequestDispatcher("/WEB-INF/home.jsp").forward(request,response);
}
}
My class that contain the database connexion:
package com.hopital.database;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import java.sql.PreparedStatement;
import java.util.ArrayList;
import java.util.List;
import com.hopital.projet.chamber;
public class Recup_Insert {
public List<chamber> recup_chmabre(){
List<chamber> chambers= new ArrayList<chamber>();
//charger les drivers
try{
Class.forName("com.mysql.jdbc.Driver");
}catch( ClassNotFoundException e){
}
//Connexion
Connection connexion=null;
Statement statement=null;
ResultSet resultat = null;
try {
connexion = DriverManager.getConnection("jdbc:mysql://localhost:3306/hopital", "root", "3636");
statement= connexion.createStatement();
resultat= statement.executeQuery("SELECT * FROM CHAMBER;");
while(resultat.next()){
int etage = resultat.getInt("etage");
int ID_pat = resultat.getInt("ID_pat");
int num = resultat.getInt("num");
int nom_lits = resultat.getInt("nom_lits");
int occupee = resultat.getInt("occupee");
chamber chamber = new chamber();
chamber.setEtage(etage);
chamber.setID_pat(ID_pat);
chamber.setNum(num);
chamber.setOccupee(occupee);
chamber.setNom_lits(nom_lits);
chambers.add(chamber);
}
} catch (SQLException e) {
e.printStackTrace();
}finally{
try{
if(resultat != null)resultat.close();
if(statement != null)statement.close();
if(connexion != null)connexion.close();
}catch(SQLException ignore){
}
}
return chambers;
}
}
AND THIS IS THE ERRORS AFTER RUNING:
The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.

Check connection URL and credentials. Try connecting with the same parameters using some SQL client.
You got this error because you cannot connect to database.
Most probably you didn't start you server. Check either it running or not, then double check port where it is running. Also check spelling on table name in database it should be "hopital".
Check For mysql-connector-java-5.1.21-bin.jar file added to Properties=>libraries=>
if not then add external jar=>mysql-connector-java-5.1.21-bin.jar
also check port number of tomcat server and mysql.
