How do I resolve ClassNotFoundException?

i have an problem with my java program i'm trying to connect to an MYSQL database but it says driver not found i've imported mysql-connector-java into the project even with output set so it exports with the program
the class:
package com.CloudyProductions.GCDSS;
import java.sql.*;
public class mysql {
public static Connection c;
static String host = "localhost";
static String port = "3306";
static String database = "";
static String username = "root";
static String password = "";
public static void connect() {
try {
Class.forName("com.mysql.jdbc.Driver");
c = DriverManager.getConnection("jdbc:mysql://" + host + ":" + port + "/" + database, username, password);
} catch (Exception ex) {
ex.printStackTrace();
}
}
}
I've added the mysql-connector to the project via maven and did what you said but now get this error:
java.lang.ClassNotFoundException: com.mysql.cj.jdbc.Driver
at java.net.URLClassLoader.findClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
at java.lang.Class.forName0(Native Method)
at java.lang.Class.forName(Unknown Source)

From this answer:
You will have to include driver jar for MySQL MySQL Connector Jar in your classpath.
If you are using command line include the path to the driver jar using the -cp parameter of java.
For example:
java -cp C:\path\to\connector.jar Main

You need to set your mysql driver jar into the classpath through command line as follows.
//for windows
set CLASSPATH=PATH_TO_JAR
//for unix
export CLASSPATH=PATH_TO_JAR
Or you can add it during execution of your application directly using -cp as,
java -cp PATH_TO_JAR your_class_app
or -classpath
java -classpath PATH_TO_JAR your_class_app

JDBC problems connectiong to sql server [duplicate]

Cannot load driver class: com.microsoft.jdbc.sqlserver.SQLServerDriver

Closed 4 years ago.
i'm trying to establishing a connection from java to sql server. I'm using jdk 8 1.8 and sql server 2014, and this is my code:
package test.prova;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;
public class Provaconn {
public static void main(String[] args) throws Exception {
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
Connection m_Connection = DriverManager.getConnection(
"jdbc:microsoft:sqlserver://srvdatiorim14.saga.locale;DatabaseName=mydbname", "myuser", "mypw");
Statement m_Statement = m_Connection.createStatement();
String query = "SELECT * FROM trasco_proprieta";
ResultSet m_ResultSet = m_Statement.executeQuery(query);
while (m_ResultSet.next()) {
System.out.println(m_ResultSet.getString(1) + ", " + m_ResultSet.getString(2) + ", "
+ m_ResultSet.getString(3));
}
}
but i get the following error:
Exception in thread "main" java.lang.ClassNotFoundException: com.microsoft.jdbc.sqlserver.SQLServerDriver

i've already searched for a solution in various topic, i've tried lot of various adjustment, but still i got this error.
I've also imported the jdbc driver jar, from both maven dependency and external library (i tried different version of it as you can see):
any suggestion on how to solve this? T
Thank,
Serph
EDIT - SOLVED
after changing the Class.forName into te one suggest in the answer, i also modified the url which was wrong. Changed it from
jdbc:microsoft:sqlserver://...
to
jdbc:sqlserver//...

if you use this jar file: http://www.java2s.com/Code/Jar/s/Downloadsqljdbc420jar.htm
you must change:
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
to
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");

JDBC connection MSQL error "No suitable driver found" [duplicate]

while(myRs.next()){
System.out.println(myRs.getString("last")+ "," + myRs.getString("first"));
}
}
catch(Exception e){
e.printStackTrace();
}
}
}

The error is either because your URL is wrong, or the JDBC driver is missing.
A JDBC URL typically looks like this jdbc:mysql://localhost:3306/mysql. I'm not sure why you have an # in there. But that probably is the problem.
You can pinpoint if the problem is in the classpath by loading the driver like this.
Class.forName("com.mysql.jdbc.Driver");
EDIT :
The Class.forName isn't JDBC specific. It's simply loading the Driver class into the current class loader. Nothing related to databases there.
Prior to JDBC 4.0 you had to initialize the driver this way. I guess since this worked, you must be using a lesser version.

java.lang.NoClassDefFoundError: com/healthmarketscience/jackcess/util/ErrorHandler in ms access connectivity with java8

I am trying to connect Ms Access database with java 8 version. But as in this version jdbcodbcbridge driver has been removed, so following jar files need to be included :
**ucanaccess-x.x.x.jar
HSQLDB (hsqldb.jar, version 2.2.5 or newer)
,Jackcess (jackcess-2.x.x.jar)
,commons-lang (commons-lang-2.6.jar, or newer 2.x version)
,commons-logging (commons-logging-1.1.1.jar, or newer 1.x version)**
I have bought all these jar files in my eclipse through Build Path option.
But still when i am executing the following code it is coming up with error as:
Exception in thread "main" java.lang.NoClassDefFoundError:
com/healthmarketscience/jackcess/util/ErrorHandler at java.lang.Class.forName0(Native Method) at
java.lang.Class.forName(Unknown Source) at

java.net.URLClassLoader.findClass(Unknown Source) at
java.lang.ClassLoader.loadClass(Unknown Source) at

And my code is:
import java.sql.*;
import java.util.*;
import com.healthmarketscience.jackcess.util.ErrorHandler;
public class JDBCDemo {
public static void main(String args[]) throws Exception
{
Class.forName("net.ucanaccess.jdbc.UcanaccessDriver");
Connection con=DriverManager.getConnection("jdbc:ucanaccess://C:\\Users\\isha\\Desktop\\StudentData.accdb");
Statement stmt=con.createStatement();
String str="insert into NameData values(4,'ram')";
stmt.executeUpdate(str);
String s="select * from NameData";
ResultSet res=stmt.executeQuery(s);
while(res.next()){
System.out.println(res.getString(1)+":"+res.getString(2));
Enumeration e=DriverManager.getDrivers();
while(e.hasMoreElements()){
Driver d=(Driver)e.nextElement();
System.out.println(d.getClass().getName());
}
}
}
}

You have an old obsolete version of jackcess in your classpath. Please add to your classpath ucanaccess.jar the jars in the folder lib of the specific ucanaccess distribution you're using.

String str="insert into NameData values(4,'ram')";
in which columns you insert this values?

Error connecting Java 8 with Access: No suitable driver found [duplicate]

This question already has an answer here:
Manipulating an Access database from Java without ODBC
(1 answer)
Closed 6 years ago.
I want to connect Java 8 with Access but the following error occurs and I don't know how to fix it. I always get this error:
java.sql.SQLException: No suitable driver found for jdbc:ucanaccess://C:/Users/Ghazi/workspace/java w access/login.accdb
I added 4 libraries:
hsqldb.jar
jackcess-2.0.7.jar
org.apache.commons.lang-2.6-source.jar
org.apache.commons.loggin-1.1.1-source.jar
This is my code
import java.sql.*;
public class DbConnection {
Connection con;
Statement st;
DbConnection(){
dbconnect();
}
//-----------------------
public void dbconnect(){
try
{
Connection conn=DriverManager.getConnection("jdbc:ucanaccess://C:/Users/Ghazi/workspace/java w access/login.accdb");
Statement stment = conn.createStatement();
}
catch(Exception err)
{
System.out.println(err);
}
}
//--------------------------
public static void main(String[]args){
DbConnection ob=new DbConnection();
}//end main
}

Try adding "Class.forName():
public void dbconnect(){
try {
Class.forName("net.ucanaccess.jdbc.UcanaccessDriver");
Connection conn=DriverManager.getConnection("jdbc:ucanaccess://C:/Users/Ghazi/workspace/java w access/login.accdb");
Statement stment = conn.createStatement();
}
catch(Exception err) {
System.out.println(err);
}
}
The basic problem is that earlier versions of Java/JDBC used ODBC to connect to MS-Access ... and the ODBC driver has been removed from Java 8.
Two alternatives are to use:
1) UCanAccess: http://ucanaccess.sourceforge.net/site.html
... or ...
2) Jackcess (Jackcess 2.0: New crunchy outside, same yummy filling!): http://jackcess.sourceforge.net/
If that doesn't work:
3) Please specify what what IDE you're using (Eclipse, etc - if applicable)
4) Make sure your jackcess-2.0.7.jar is explicitly included in the CLASSPATH (how to do this depends on your IDE)
5) Consider using a directory without spaces in the name

I added 4 libraries
You need five (5) libraries. You forgot to add the "ucanaccess-x.y.z.jar" file itself.
