I am trying to connect to a mysql database by using this simple code.
import java.sql.*;
public class OdbcAccessConnection_1 {
public static void main(String [] args) {
Connection con = null;
try {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver") ;
// Connect with a url string
con = DriverManager.getConnection("jdbc:mysql://localhost/books","root","1234");
System.out.println("Connection ok.");
con.close();
} catch (Exception e) {
System.err.println("Exception: "+e.getMessage());
e.printStackTrace();
}
}
}
All it does is tell me if the connection is working. There is no problem with my database and this code/connection work on netbeans. The StackTrace i am getting is -
the java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost/books
at java.sql.DriverManager.getConnection(DriverManager.java:602)
at java.sql.DriverManager.getConnection(DriverManager.java:185)
at OdbcAccessConnection_1.main(OdbcAccessConnection_1.java:13)
I am working on 64 bit windows 7 and using 5.1 versions of the Connector/ODBC driver 64 bit. On the ODBC all seems to connect and the test was successful. But when i run the code i get the stack trace above. I am missing something very simple so any input and help would be very much appreciated.
Thank you:)
Go to Run menu in netbeans or whatever IDE you are using
=>Set Project Configuration then Customize.Then choose the Libraries on left dropdown menu
Add your appropriate driver file either jar or folder.
Click OK.
jdbc:mysql://localhost/books is a URL that you use to connect to MySQL directly, using the MySQL JDBC driver. The URL used by the JDBC/ODBC driver is different (see http://docs.oracle.com/javase/1.3/docs/guide/jdbc/getstart/bridge.doc.html).
The usage of this JDBC/ODBC bridge is discouraged, and should only be used to access a database that doesn't provide any JDBC driver. This is not the case of MySQL. Use Connector/J, their JDBC driver. Once you have this driver in your classpath, you can use the URL you're currently using, and remove the JDBC/ODBC driver from your classpath (and its loading from your code).
con = DriverManager.getConnection("jdbc:mysql://localhost:3306/books","root","1234");
This error creeped on me because I forgot to add the Class.forName line. The mysql driver jar was on the classpath but no one implicitly loads the driver class, so the session factory can't find any driver classes loaded. Thus the purpose of this line.
In your case, you're loading the wrong thing. It should be Class.forName("com.mysql.jdbc.Driver") if you intend to use it with a jdbc:mysql:// connection.
best solution bhai logo -:
go to JCreator configure menu then click to options then JDK profiles then double click to whatever the version u r using automatically mention there then click to add archive then go to that path -> C:\Program Files\MySQL\MySQL Tools for 5.0\java\lib\mysql-connector-java-5.0.4-bin.jar press ok.

I receive the following error msg when attempting to connect to a derby network server:
java.sql.SQLException: No suitable driver found for jdbc:derby://localhost/studentdb;create=true
Derby is properly installed and all environment variables set. I am able to start the derby NetworkServerControl from a Windows command prompt with the following command:
java org.apache.derby.drda.NetworkServerControl start -h localhost
,and I can do this from any location within my system's directory tree.
I can start the derby ij client from within a Windows command prompt with the command:
java org.apache.derby.tools.ij
,again, from any location within my system's directory tree.
But the code snippet below is unable to make this connection:
public static void main(String[] args) {
Connection conn = null;
String url = "jdbc:derby://localhost/studentdb;create=true";
//the error happens here, the program executes no further
conn = DriverManager.getConnection(url,null);
Statement stmt = conn.createStatement();
}
Placing the port value in the url string makes no difference.
Any suggestions would be much appreciated.
You must add the derby jdbc driver to your classpath (from derbyclient.jar, since this is the ClientDriver), then use this instruction to load the driver :
Class.forName("org.apache.derby.jdbc.ClientDriver");
So I encountered this error and it was quite an irritating and hectic task to resolve this. But in the end, I managed to find a perfect video that made me install derby from the start and guided me perfectly on how to install it. However, there is one more step after the video.
Watch this video if you have set up JavaFX packages and are able to run the program normally, but facing
"java.sql.SQLException: No suitable driver found for jdbc:derby://localhost:1527/DBNAME;create=true" issue when trying to run with the database.
Link to the tutorial -> https://www.youtube.com/watch?v=OKiBsWbgrMw
Now after this is set up you will now be able to start/stop the database (via the services tab) and will be able to connect with the DB. But the issue will still persist in trying to edit the DB.
To rectify this, follow the steps ->
Right click on project ---> Properties ---> Libraries ---> Click on '+' in Classpath ---> Add jar/folder ---> Go to the lib folder inside the derby and select derbyclient.jar

I am getting java.lang.ClassNotFoundException on loading sun.jdbc.odbc.JdbcOdbcDriver using Class.forName().
I am using MySQL as Data Source and I have added Data Source Name in ODBC Data Source Administrator (on Windows 8).
Here is the code:
class Connect {
check() {
try {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
}
}
Output:
java.lang.ClassNotFoundException: sun.jdbc.odbc.JdbcOdbcDriver
Are you using Java 8? The class is no longer present there (more info). You could install Java 7 if you need to use it.
This happened to me once, and what i did was importing the mysql jdbc library that came with the product when i downloaded it, after that i used the driver as it is explained in the page:
http://dev.mysql.com/doc/connector-j/en/connector-j-usagenotes-connect-drivermanager.html
hope this could help you
I connect to a database:
void connectToDataBase(){
dataManager_ref = new DataBaseConfigurationManager();
try
{
connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/dataBase","root","");
System.out.println("Connection successful");
}
catch (Exception e)
{
System.err.println("Got an exception! ");
System.err.println(e.getMessage());
}
}
I implemented a JAR File for the driver:
mysql-connector-java-5.1.17-bin.jar
and imported it into the servlet
import java.sql.DriverManager;
this isnt the first time I use this database (tho the first time with Java EE web). This time I get the following exception:
No suitable driver found for jdbc:mysql://localhost:3306/dataBase
The application is running on a glassfish server 3.1, can I even use a database on a mysql server here? Can somebody help please
thanks in advance,
Daniel
You sometimes need to load the Driver class explicitly in order for the DriverManager to be aware of it.
Try this
Class.forName("com.mysql.jdbc.Driver");
Before you call the DriverManager
You can add a CLASSPATH variable in Environmental System variables, and set the path to your connector, path including name of connector.jar.
Also mysql-connector-java-5.1.17-bin.jar is showing some incompatibilities in accessing. it gave me lots of errors, so i had to go bac to 5.0.x versions
I am attempting to access my SQLite3 database in a Java Applet. When I run my code to connect to the database I get this error No suitable driver found for a.db, how can I fix it?
Now I am not entirely sure I have actually installed the correct driver...I will tell you what I have done & could you tell me what else I need to do to make Eclipse IDE find the SQLitejdbc driver:
BK info: On windows 7, using Eclipse Helios Java
I have a SQLite3 database created in python & I want to read it in my Java Applet
I have downloaded the file sqlitejdbc-V056.jar from http://www.zentus.com/sqlitejdbc/
Then I copied & pasted the above file to the paths C:\Program Files\Java\jre6\lib & C:\Program Files\Java\jre6\lib\ext
Run the following code in a Java Applet & get an exception thrown with the text: "No suitable driver found for a.db"
Class.forName("org.sqlite.JDBC");
Connection conn = DriverManager.getConnection("a.db"); // exception thrown here
Any information would be really helpful. Do I need to import the driver into my Eclipse project?
Try this:-
Class.forName("org.sqlite.JDBC");
Connection conn = DriverManager.getConnection("jdbc:sqlite:a.db");
I am getting a java.sql.SQLException: No suitable driver when I am trying to connect to a database with Java. I am on Mac OS 10.5 using the NetBeans IDE. It seems to be having trouble with the EmbeddedDriver, but I'm not sure what I am missing:
public class A
{
Connection conn = null;
public A(String URL, String username, String password) throws SQLException
{
try
{
Class.forName("org.apache.derby.jdbc.EmbeddedDriver");
conn = DriverManager.getConnection(URL, username, password);
}
catch (SQLException sqlException)
{
sqlException.printStackTrace();
invalidate();
}
catch (ClassNotFoundException classNotFound)
{
classNotFound.printStackTrace();
invalidate();
}
}
}
"No suitable driver" usually means that the URL you've supplied to connect has incorrect syntax. What is your URL?
The server version would have a host and port; I believe the embedded URL should be "jdbc:derby:flixnet", according to these docs: http://db.apache.org/derby/papers/DerbyTut/embedded_intro.html
Use "org.apache.derby.jdbc.ClientDriver".
As i see you are accessing a derby server not an embedded database.
It is declared as a constant here:
final String DATABASE_URL = "jdbc:derby://localhost:1527/flixnet";
Don't ask about the name... I got this URL by right-clicking the database in NetBeans and then going to Properties -> Database URL.
And I have added the derby.jar and derbyclient.jar files from /Applications/NetBeans/glassfish-v3-prelude/javadb/lib/derby.jar and derbyclient.jar from the same directory.
Did you add the derbyclient.jar to the "Libraries" folder in your Netbeans project?
I had the same problem.
Try this:
Make sure you update your JDK and Netbeans to latest version
Right click your project's Libraries
Choosing "Add Library..."
Find and choose "Java DB Driver", then click "Add Library"
That's how I solved the problem, I hope this will help some new programmer like me:)
PS It will add "derbyclient.jar" for you
