JDBC Connection Error: No Suitable Driver for Derby Connection
When attempting to connect to a Derby database using JDBC, you may encounter the error: "SQLException: No suitable driver found for jdbc:derby://localhost:1527". This issue stems from either missing driver loading or an incorrectly formatted JDBC URL.
Driver Loading
Ensure that the derbyclient.jar file is included in your classpath. This jar contains the Derby JDBC driver required for establishing connections.
JDBC URL Malformation
The JDBC URL should contain the database name at the end. For example, if your database is named "dbname", the correct URL would be:
jdbc:derby://localhost:1527/dbname
Additionally, you can specify an absolute path to the database location:
jdbc:derby://localhost:1527//home/pascal/derbyDBs/dbname
Server Mode Driver Considerations
When working with Derby in server mode, you must load the ClientDriver:
org.apache.derby.jdbc.ClientDriver
