I'm trying to write a program with embedded Derby, but when I run it, it displays:
run:
Jul 14, 2017 9:19:54 PM gfdh.Login Doconnect
SEVERE: null
java.sql.SQLException: No suitable driver found for jdbc:derby:gdtu:create=true
...
Code:
public class Login extends javax.swing.JFrame {
Connection con;
Statement stmt;
ResultSet rs;
private static final String DRIVER = "org.apache.derby.jdbc.EmbeddedDriver";
private static final String JDBC_URL = "jdbc:derby:gdtu:create=true";
public Login(){
initComponents();
Doconnect();
}
private void Doconnect(){
try {
this.con = DriverManager.getConnection(JDBC_URL);
if(this.con != null){
System.out.println("Connected to database");
}
} catch (SQLException ex) {
Logger.getLogger(Login.class.getName()).log(Level.SEVERE, null, ex);
}
}
}
}

the column after gdtu should be replaced with semicolon.
private static final String JDBC_URL = "jdbc:derby:gdtu;create=true";

This looks like to a configuration problem,
Did you set your classpath variable?
If you are using:
Windows - 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:
Once you have done try printing the path to see if the variable are correctly configured:
Windows: echo %CLASSPATH%
Unix: echo $CLASSPATH
then execute java org.apache.derby.tools.sysinfo
to see the info of your server
[EDIT]: Sorry i miss to add the derby tools

Check that derbyclient.jar
is on the class path and that you are loading the appropriate driver org.apache.derby.jdbc.ClientDriver
when working in server mode.
