PESSOAL preciso de um link que vá direto a página da apache onde está o arquivo que devo baixar o jar org.apache.derby.jdbc.EmbeddedDriver porque eu entro lá e tem tantos que eu não sei qual baixar e eu estou ficando nervosa pois não acho e o meu tempo está acabando.

Se você colocar o derby.jar e o derbyClient.jar não funciona?

São esses dois que têm o JDBC driver.

Até!

O que será?

Esse erro dá a impressão que o tal JAR foi repetido algumas vezes no seu classpath. Você pôs só uma versão do derby.jar e derbyClient.jar, ou eles estão copiados a torto e a direito pelo seu Java (por exemplo, eles foram copiados acidentalmente em jre\lib\ext?)

É realmente estava já corrigido mas agra a mensagem é:

java.sql.SQLException: No suitable driver found for jdbc:derby:localhost:1527

narinha 7 de dez. de 2007

Oi eu mudei o endereço do meu programa para

package persistencia;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;

public class PersistenciaConexao {
	
	public static Connection conexao;
	static {
		try{
			Class.forName("org.apache.derby.jdbc.ClientDriver");  

			conexao = DriverManager.getConnection("jdbc:derby:","D:/TrabFinal/EletronicaProjeto/PjEletronica" 
					,"bancoeletronica");
		}catch(Exception e){
			e.printStackTrace();
		};
     }

	public PersistenciaConexao(){
		super();  
	}

	public PreparedStatement prepareStatement(String string) {
		return null;
	}
	
	   public static void main(String[] args) {
	        new PersistenciaConexao();
	   }
}

e agora a mensagem é:

java.sql.SQLException: Banco de dados ‘’ não encontrado.

Amigo, uma dica pra vc.

Quando sabe a classe que quer, mas não sabe em que JAR essa classe encontra-se, dá uma olhada no site JarFinder que se existir, ele encontra. dá uma olhada: http://www.jarfinder.com/?class=org.apache.derby.jdbc.EmbeddedDriver&submit=search
