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 in the process of getting a third-party JDBC driver (Snowflake) configured in SQL Dev, but running into issues. I am unsure how to get paths set in Preferences > Database > Third Party JDBC Drivers. I noticed on a few posts that this is related to the CLASSPATH env variable, but this didn't seem to work (the field was blank in the related window, attempting to load from the Connections tab gave the error: Could not initialize class com.mysql.jdbc.Driver).
I created the new connection by modifying the connections.json script in %USERPROFILE%\AppData\Romaing\SQL Developer\systemversion\o.jdeveloper.db.connection directory. This works, as it to populates in the connections tab after completion. Currently this script is in PowerShell, apologies I do not know Oracle applications well:
$TestPath = [Environment]::GetEnvironmentVariable('CLASSPATH', 'Machine')
If ($TestPath.Contains('C:\Oracle\sqldeveloper\jdbc\jdbc-proxy.jar'))
{
Echo "Path Environment Variable already set. Skipping creation."
}
else
{
$path = [Environment]::GetEnvironmentVariable('CLASSPATH', 'Machine')
$newpath = $path + ';C:\Oracle\sqldeveloper\jdbc\jdbc-proxy.jar'
[Environment]::SetEnvironmentVariable("CLASSPATH", $newpath, 'Machine')
}
If ($TestPath.Contains('C:\Oracle\sqldeveloper\jdbc\snowflake-jdbc.jar'))
{
Echo "Path Environment Variable already set. Skipping creation."
}
else
{
$path2 = [Environment]::GetEnvironmentVariable('CLASSPATH', 'Machine')
$newpath2 = $path2 + ';C:\Oracle\sqldeveloper\jdbc\snowflake-jdbc.jar'
[Environment]::SetEnvironmentVariable("CLASSPATH", $newpath2, 'Machine')
}
Here is a link to the process I am attempting to accomplish (different driver): https://www.geeksforgeeks.org/how-to-install-a-jdbc-driver-in-oracle-sql-developer/
You're not going to succeed here. SQL Developer only allows specific 3rd party JDBC drivers, and Snowflake isn't one of them.
Sybase ASE, SQL Server, Teradata, DB2 LUW, AWS Redshift, and MySQL are all allowed. We're working on PostgreSQL for formal migration support, the driver/connections should work already.
There are several .txt files in my Java gradle project, which I use to populate a database using the MySQL statement LOAD DATA LOCAL INFILE in sql scripts.
There is a MySQL server running on my PC, whose hostname is 127.0.0.1, port is 3306 and DB name is test, so in the gradle project's build.gradle file I configure flyway in the following way:
flyway {
url = 'jdbc:mysql://127.0.0.1:3306/test'
user = 'root'
password = '111111'
}
An example .sql file is
LOAD DATA LOCAL INFILE 'data/categories.txt' INTO TABLE category
FIELDS TERMINATED BY '|'
LINES TERMINATED BY '\n';
but when running migration using gradle flywayMigrate -i, I got the following error:
Loading local data is disabled; this must be enabled on both the client and server sides
I think I have enabled it in the server side as shown below, which is a MySQL Command Line Client screenshot.
Hope I did it correctly.
After this step, the error still show up, so I think I also need to enable it in the client side, which is in the Java gradle project, is that correct?
Based on https://dev.mysql.com/doc/refman/8.0/en/load-data-local-security.html, I should set ENABLE_LOCAL_INFILE = 1.
But how to do that? In where should I add this ENABLE_LOCAL_INFILE = 1 connection string?
Hope someone can help me.
Thanks in advance!
Use the JDBC connection string property allowLoadLocalInfile=true
See https://dev.mysql.com/doc/connector-j/8.0/en/connector-j-connp-props-security.html#cj-conn-prop_allowLoadLocalInfile

SQLException: No suitable driver found for jdbc:derby://localhost:1527

Closed 7 years ago.
I am trying to create a new SQL database with this Java program
import java.sql.*; //Needed for JDBC classes
public class BuildPhonebookDB {
public static void main(String[] args) throws Exception{
//Create a named constant for the URL
final String DB_URL = "jdbc:derby:Phonebook;create=true";
try {
//Create a connection to the database.
Connection conn = DriverManager.getConnection(DB_URL);
//Create a Statement object.
Statement stmt = conn.createStatement();
//Create the Entries table
stmt.execute("CREATE TABLE Entries (" +
"Name CHAR(20)"+
"Number INTEGER)"
);
System.out.println("Database Connected");
//Close the connection
conn.close();
}
catch(Exception ex) {
System.out.println(ex.getMessage());
}
}
}
When I try to run the program I get an error that:
No suitable driver found for jdbc:derby:Phonebook;create=true
I have looked at various other similar posts on Stack Overflow, such as this one, but none help. I have seen things about a driver jar, but I don't know what this is, if I need to edit this, could someone help me through it?
Thanks for any help
Did you see this guide and have you complited all step of this guide?
Apache Derby
Download Derby Download the binary Apache Derby distribution from the
Derby web site at http://db.apache.org/derby/derby_downloads.html.
These tutorial instructions use version 10.12.1.1 and assume you
downloaded one of the binary distribution files listed in the table
below:
Operating System Download File Windows db-derby-10.12.1.1-bin.zip
UNIX, Linux, and Mac db-derby-10.12.1.1-bin.tar.gz If a more recent
release is available, download that, then substitute that version
number for 10.12.1.1 in the following instructions.
Install Derby Choose the directory into which you want to install the
Derby software. You must have write permissions to this directory. The
sample instructions below use C:\Apache for Windows and /opt/Apache
for UNIX; be sure to use your actual location. Copy the software
distribution to the location you choose, then extract it as shown
below.
Windows (use your extraction tool e.g. WinZip -- these instructions
use mks unzip):
mkdir C:\Apache copy db-derby-10.12.1.1-bin.zip
> C:\Apache cd C:\Apache unzip db-derby-10.12.1.1-bin.zip
UNIX:
mkdir /opt/Apache cp db-derby-10.12.1.1-bin.tar.gz /opt/Apache
> cd /opt/Apache tar xzvf db-derby-10.12.1.1-bin.tar.gz
In both cases, the software will now be extracted into a subdirectory
named db-derby-10.12.1.1-bin.
Set DERBY_INSTALL Set the DERBY_INSTALL variable to the location where
you installed Derby. Examples are shown below, but be sure to use the
actual location on your system:
Windows: C:\> set DERBY_INSTALL=C:\Apache\db-derby-10.12.1.1-bin
UNIX Korn Shell:
$ export
> DERBY_INSTALL=/opt/Apache/db-derby-10.12.1.1-bin
Configure Embedded Derby To use Derby in its embedded mode set your
CLASSPATH to include the jar files listed below:
derby.jar: contains the Derby engine and the Derby Embedded JDBC
driver derbytools.jar: optional, provides the ij tool that is used by
a couple of sections in this tutorial You can set your CLASSPATH
explicitly with the command shown below:
Windows:
C:\> set
> CLASSPATH=%DERBY_INSTALL%\lib\derby.jar;%DERBY_INSTALL%\lib\derbytools.jar
;.
UNIX:
$ export
> CLASSPATH=$DERBY_INSTALL/lib/derby.jar:$DERBY_INSTALL/lib/derbytools.jar:.
...
Step 3: Embedded Derby
When an application accesses a Derby database using the Embedded Derby
JDBC driver, the Derby engine does not run in a separate process, and
there are no separate database processes to start up and shut down.
Instead, the Derby database engine runs inside the same Java Virtual
Machine (JVM) as the application. So, Derby becomes part of the
application just like any other jar file that the application uses.
Figure 1 depicts this embedded architecture.
Set the environment
To set up the environment, follow the "Configure Embedded Derby"
instructions.
Use this before you get the connection from the driver:
Class.forName("org.apache.derby.jdbc.ClientDriver").newInstance();
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");
