SQLException: No suitable driver found for jdbc:derby

Question

I've found this question before but non of the answers work for me! I've got this error after running:

SQLException: No suitable driver found for jdbc:derby://localhost:1527//RIHANNA-PC/Users/javadb

I've add derbyclient.jar to Library.but I didn't get any different result.I also don't want to create a new database.

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                         
    // TODO add your handling code here:
    String userid="a", password = "a";

 //   "jdbc:derby://localhost:1527//RIHANNA-PC/Users/javadb"
    String url = "jdbc:derby://localhost:1527//RIHANNA-PC/Users/javadb";
    Statement stmt;
    Connection con;
    String createString="select * from tbl_operator where user_id='" + jTextField1.getText() +  "' and pwd='" + jTextField2.getText() + "'";
    ResultSet rs;
    try {
        con=DriverManager.getConnection(url,userid, password);
        stmt = con.createStatement();
        rs=stmt.executeQuery(createString);

Answer 1

Do you load Derby JDBC driver? You can do it using the following java startup command:

java -Djdbc.drivers=org.apache.derby.jdbc.EmbeddedDriver

For another way to load it see docs: http://db.apache.org/derby/docs/10.7/devguide/cdevdvlp40653.html

Answer 2

I met the same question. If you want to connect the javadb by netwrok,you should be startNetworkServer,and create the database in this status.

And the driver is "org.apache.derby.jdbc.ClientDriver"
