how using jdbc driver with java modules

I am programming a database application in Java and would like to use java modules. The following code crashes with an error:

package dm;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

public static void main(final String[] args) {
      final String dbUrl =
         "jdbc:oracle:thin:@ldap://server/database";

      try {

         final Connection connection =
            DriverManager.getConnection(dbUrl, "user", "password");
      } catch (final SQLException e) {
         e.printStackTrace();
      }
   }

as module-info.java I use:

module sandbox2 {

   exports dm;
   requires java.sql;
}

When I run this code, I get the following error message

java.sql.SQLException: ORA-17858: JNDI package failure: javax.naming.NamingException: Could not resolve a valid ldap host

If I delete module-info.java the code runs without errors, but I want to use java moduls. Does anyone know how to specify the jdbc driver correctly in module-info.java or does anyone have another solution? I include the jdbc driver with a maven build file:

<dependencies>
      <dependency>
         <groupId>com.oracle.database.jdbc</groupId>
         <artifactId>ojdbc11</artifactId>
         <version>23.4.0.24.05</version>
      </dependency>
</dependencies>

Thanks

changed jdbc driver version, hoped resolves the problem, but didn't
