I'm trying to create a connection with postgresql using a gem called RJB (Ruby-Java bridge) by importing the "Class" class and the "DriverManager" class, and running the following code:
Class.forName("org.postgresql.Driver")
url = "jdbc:postgresql://localhost:5432/database"
con = DriverManager.getConnection(url, 'root', '123')
but I get the following error:
SQLException: No suitable driver found for jdbc:postgresql://localhost:5432/database
is there a way to make it work?
Thanks!
Have you installed the gem? Meaning have you ran the command that installs the gem on the gemfile you're working on.

I am trying to connect to my Hive server using JDBC connection.
I've the following JAR file in my JAVA_HOME:
HIVEJDBC41.jar
hadoop-common.jar
But when I run my code jaydebeapi.connect('org.apache.hive.jdbc.HiveDriver', url)
It gives me the following error:
raise _RUNTIMEEXCEPTION.PYEXC("Class %s not found" % name)
jpype._jexception.RuntimeExceptionPyRaisable: java.lang.RuntimeException: Class org.apache.hive.jdbc.HiveDriver not found
Note: My connection needs to be using JDBC connection.
Anyone knows what I am missing?
There is mismatch of JDBC jar version
try hive-jdbc 2.3.7
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

Quite exciting to find this jdbc driver for ms access.
However, when I try to test it with Oracle SQL Developer, I got:
Status : Failure -Test failed: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
Quoted from UCanAccess website:
Because it is a pure java implementation it run in both Windows and non-Windows Operative Systems(e.g., linux/unix). No ODBC needed.
What am I missing? Or I must configure ODBC in Windows environment?
You shouldn't be using an ODBC URL, to open a hypothetical test.mdb in the user's home directory you might use something like
File file = new File(System.getProperty("user.home"), "test.mdb");
Connection conn = DriverManager.getConnection("jdbc:ucanaccess://" +
file.getPath());
The JDBC url begins with jdbc:ucanaccess:// which is followed by the Access database file path.
Finally, make sure you have the required dependencies (which are documented as)
jackcess-2.0.0.jar or later
commons-lang-2.4.jar
commons-logging-1.0.4.jar
hsqldb.jar(2.2.5)
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 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");
