ClassNotFound & No Suitable Driver, where did I go wrong?

I have created a program that works perfectly in the IDE on NetBeans, but anytime I build the .jar file, the database connection stops working. I've already added the CLASSPATH to the MySQL Connector, as well as defined Class.forName("com.mysql.jdbc.Driver"); Still nothing..
try {
Class.forName("com.mysql.jdbc.Driver");
String url = "jdbc:mysql://localhost:3306/gearheads";
Connection conn = DriverManager.getConnection(url,"root","HellOnEarth202021");
Statement stmt = conn.createStatement();
ResultSet rs;
String pid = txt_staffID.getText();
rs = stmt.executeQuery("SELECT name,timeraccess FROM staff WHERE staffid = '"+pid+"'");
while ( rs.next() ) {
String timeraccess = rs.getString("timeraccess");
String staffName = rs.getString("name");
getLogin = staffName;
System.out.println(staffName);
System.out.println("Users Admin Level: " + timeraccess);
if ( timeraccess.equals("1")) {
this.dispose();
new menu().setVisible(true);
System.out.println("Access Granted");
}else
System.out.println("Access Restricted.");
}
conn.close();
} catch (Exception e) {
System.err.println("Got an exception! ");
txt_staffID.setText(e.toString());
System.err.println(e.getMessage());
}
This, as it stands, outputs:
java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
Where taking out the Class.forName outputs:
java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/gearheads
Please help me. This link is a screenshot of my libraries.
My Libraries:

If its runnning correctly inside Netbeans, then the MySQL driver is correct.
You have to search for Manifest file (MANIFEST.MF) and probably will have to unjar the contents of the driver inside your own JAR file.
I'll leave this answer by now, but will try to gather the details to bring it back here.
I also use NetBeans and when I generate the JAR file, its already copying the dependant libraries and generating the correct MANIFEST.MF.
I ended up with the following structure
MyProject\dist\lib\JdbcDriver.jar
and
MyProject\dist\MyProject.jar
Inside MyProject.jar, I have the following MANIFEST.MF:
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.9.7
Created-By: 1.8.0_201-b09 (Oracle Corporation)
Class-Path: lib/JdbcDriver.jar
X-COMMENT: Main-Class will be added automatically by build
Main-Class: myproject.MyMainClass
Please, verify with you are copying the lib folder altogether with your JAR file.
Just to leave here the final solution (#Nick Media final comment): you have to check "Copy Dependent Libraries" in Build>Packaging Project Properties.

It is not clear exactly what you are doing wrong, but you are clearly doing something incorrectly:
It is often better to use DriverManager.getConnection rather than Class.forName and a specific driver class name. This is the approach recommended by the Oracle Java Tutorial; see https://docs.oracle.com/javase/tutorial/jdbc/basics/connecting.html
If you are loading the driver via its classname, use com.mysql.jdbc.Driver with MySQL Connector/J 5.x and com.mysql.cj.jdbc.Driver with MySQL Connector/J 8.x.
If this is a webapp, make sure that the relevant driver JAR file is actually in your WAR file, and/or that it is being deployed correctly.
If this is a command line app, make sure that you include the driver JAR on the runtime classpath. (Especially if you are trying to run it outside of your IDE.) Alternatively, consider creating a shaded JAR that included all of the apps dependencies. (It is a bit hard to advise since you haven't told us if you are using a build tool like Ant, Maven, Gradle, etc.)
The driver doesn't actually need to be a compile time dependency, though there is little harm in doing that. (The harm is that you might accidentally add imports to the MySQL implementation classes to your app ... and run into problems.)

No suitable driver found for jdbc:mysql://localhost:3306/world [duplicate]

The infamous java.sql.SQLException: No suitable driver found
(21 answers)
Closed 7 years ago.
Using Java, I get this error when attempting to connect to a mysql database:
java.sql.SQLException: No suitable driver found for
jdbc:mysql://localhost:3306/mysql at
java.sql.DriverManager.getConnection(Unknown Source)
at java.sql.DriverManager.getConnection(Unknown Source)
at MyTest1.main(MyTest1.java:28)
I'm using the mysql-connector-java-5.1.18-bin.jar driver. It is in my build path. I have restarted MySQL. I've also logged on from the command line with root and no password and it connected fine. I'm not currently seeing a port 3306 in netstat. Previously I was getting a different error (I didn't change the code). The error was "jdbc mysql Access denied for user 'root'#'localhost password NO"
try {
Class.forName("com.mysql.jdbc.Driver");
}
catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
String url = "jdbc:mysql://localhost:3306/mysql";
Connection con = DriverManager.getConnection(url, "root", "");
}
catch (Exception e){
e.printStackTrace();
}

In this particular case (assuming that the Class#forName() didn't throw an exception; your code is namely continuing with running instead of throwing the exception), this SQLException means that Driver#acceptsURL() has returned false for any of the loaded drivers.
And indeed, your JDBC URL is wrong:
String url = "'jdbc:mysql://localhost:3306/mysql";
Remove the singlequote:
String url = "jdbc:mysql://localhost:3306/mysql";

You have to set classpath for mysql-connector.jar
In eclipse, use the build path
If you are developing any web app, you have to put mysql-connector to the lib folder of WEB-INF Directory of your web-app

When using Netbean, go under project tab and click the dropdown button there to select Libraries folder. Right Click on d Library folder and select 'Add JAR/Folder'. Locate the mysql-connectore-java.*.jar file where u have it on ur system.
This worked for me and I hope it does for u too.
Revert if u encounter any problem

This error happened to me, generally it'll be a problem due to not including the mysql-connector.jar in your eclipse project (or your IDE).
In my case, it was because of a problem on the OS.
I was editing a table in phpmyadmin, and mysql hung, I restarted Ubuntu. I cleaned the project without being successful. This morning, when I've tried the web server, it work perfectly the first time.
At the first reboot, the OS recognized that there was a problem, and after the second one, it was fixed. I hope this will save some time to somebody that "could" have this problem!

A typographical error in the string describing the database driver can also produce the error.
A string specified as:
"jdbc:mysql//localhost:3307/dbname,"usrname","password"
can result in a "no suitable driver found" error. The colon following "mysql" is missing in this example.
The correct driver string would be:
jdbc:mysql://localhost:3307/dbname,"usrname","password"

i had same problem i fix this using if developing jsp, put mysql connetor into WEB-INF->lib folder after puting that in eclipse right click and go build-path -> configure build patha in library tab add external jar file give location where lib folder is

Just telling my resolution: in my case, the libraries and projects weren't being added automatically to the classpath (i don't know why), even clicking at the "add to build path" option. So I went on run -> run configurations -> classpath and added everything I needed through there.

( If your url is correct and still get that error messege )
Do following steps to setup the Classpath in netbeans,
Create a new folder in your project workspace and add the downloaded .jar file(eg:- mysql-connector-java-5.1.35-bin.jar )
Right click your project > properties > Libraries > ADD jar/Folder
Select the jar file in that folder you just make. And click OK.
Now you will see that .jar file will be included under the libraries. Now you will not need to use the line, Class.forName("com.mysql.jdbc.Driver"); also.
If above method did not work, check the mysql-connector version (eg:- 5.1.35) and try a newer or a suitable version for you.

connect mysql with java using eclipse

i can connect mysql with java using eclipse in a java application with these statements
String unicode = "?useUnicode=yes&characterEncoding=UTF-8";
Class.forName("com.mysql.jdbc.Driver");
con = (Connection) DriverManager.getConnection(
"jdbc:mysql://localhost:3306/ams-competation" + unicode,
username, password);
and it works good
but my problem is when i tried to connect to mysql with a server application i got this exception
java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
what am i doing wrong?thank you all
Edit
i have added mysql-connector already

I think you have not included mysql drive jar in your web project.
put mysql-connector-java.. jar file in your web projects lib folder

for that you need to add the mysql-connector jar in the classpath.
This is because eclipse is not able to find the jar file you specified.
Hence put the jar file in the server`s lib directory
another way is to put jar file it in /WEB-INF/lib eclipse itself will notice it and get it.

Did you add the MySQL driver to the server?
It depends on the application server where the jar file is needed to be added:
Apache Tomcat: $CATALINA_HOME/common/lib
GlassFish server: GLASS_FISH_INSTALL_DIR\lib
Or add it the WEB-INF/lib folder of your web application
Try adding the mysql-connector-java-5.1.20-bin.jar file (downloadable from: http://dev.mysql.com/downloads/connector/j/ ), and restart the server.

Add the Connector/J jar file to the server's classpath (or lib folder)

add my sql connection jar file to your project. Its name will be something like "mysql-connector-java-5.1.13-bin.jar"

connect connector/J 8.0.11 with eclipse oxygen by following line of code.
Class.forName("com.mysql.cj.jdbc.Driver");
conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/testing?autoReconnect=true&useSSL=false", "AF", "birru123");
Statement st = conn.createStatement();

No suitable driver found error for odbc, db2

I'm trying to connect to a remote database using the following java code, but I get an error saying no suitable driver found.
DriverManager.getConnection("odbc:db2://url:port/dbname");
Class.forName("com.ibm.db2.jcc.DB2Driver");
What could I be doing wrong?

Two comments:
1. You have to load the driver first, before trying to use it
2. If I am not mistaken, the driver you are loading is a JDBC driver for DB2 UDB, not ODBC. The connection URL for it is "jdbc:db2//host:port/database"
So your code should look something like this:
Class.forName("com.ibm.db2.jcc.DB2Driver");
DriverManager.getConnection("jdbc:db2://host_or_ip_address:port/dbname");

I found the solution...I didn't add the JAR files for the driver.

You should add jar files of db2cc.jar,db2jcc_license_cu.jar and db2jcc_license_cisuz.jar files into your classpath location and these jar files held in your db2 installation directory location under java folder you got the above jar files

I got error named no suitable driver? [duplicate]

This question already has answers here:
The infamous java.sql.SQLException: No suitable driver found
(21 answers)
Closed 7 years ago.
I couldn't find out why it shows error. I have created table named books in Oracle priorly.
create table books(num number);
Then I wrote code in Java:
Class.forName("oracle.jdbc.driver.OracleDriver");
con=DriverManager.getConnection(
"jdbc:oracle:thin:#CF:1521:orcl",
"scott",
"tiger");
Statement s=con.createStatement();
s.execute("INSERT INTO BOOKS VALUES(123)");
s.close();
con.close();
It shows error as "No suitable driver"

It seems that the oracle driver (v 1.6) is actually "called":
oracle.jdbc.OracleDriver

You need to set your classpath to point to the jar file. The one I used years ago was "ojdbc14.jar". Find the one suitable for you here.

If you are executing code from command line - make sure that the classpath is set using either $CLASSPATH environment variable or command line argument -cp [pathTo:]ojdbc14.jar or setting the ClassPath: attribute in Manifest.mf of the current executing jar
With Eclipse IDE : Check in the build path the presence of jar / or if build issues exist - check for them in the problems tab.
The version of the jar file (which can be determined from Manifest.mf file) will confirm if you are using the right package for the driver Check if your jar is not corrupt by doing a simple jar -tvf.

It shows error as "No suitable driver"
You apparently did System.out.println(e.getMessage()) instead of a e.printStackTrace(). Then you will indeed get that little information. But this message is recognizeable as being a SQLException which can basically have two causes:
The driver is not loaded.
The (wrong) JDBC URL didn't return true for Driver#acceptsURL() for any of the loaded drivers.
To fix 1, you need to ensure that you have a
Class.forName("com.example.jdbc.Driver");
in your code prior to DriverManager#getConnection() call and that you do not swallow/ignore any ClassNotFoundException which can be thrown by it by putting for example an empty catch block or just doing a System.out.println() instead of throwing it.
To fix 2, you need to ensure that the JDBC URL syntax conforms the one as specified in the JDBC driver documentation. In case of Oracle it is located here. Here's a quote:
In JDBC all url's begin with jdbc:protocol: This is the standard. After this is driver specific, and no two drivers are the same.
What is the form of a URL?
The general form of a URL is
jdbc:oracle:<drivertype>:<username/password>#<database>
The <drivertype> is one of
thin
oci
kprb
The <username/password> is either empty or of the form <username>/<password>
In your specific case, the URL looks okay, so you might have not loaded the right driver or plain ignored the ClassNotFoundException thrown by it.
