*
* Created on 16 de Fevereiro de 2005, 18:02
*/

package STI.conecta;
import java.lang.*;
import javax.swing.JOptionPane;
import java.sql.*;
import org.firebirdsql.jdbc.*;

/**

* @author Jean
*/
public class testeconct {

/** Creates a new instance of testeconct */
public testeconct() {
try
{
Class.forName("org.firebirdsql.jdbc.FBDriver");
org.firebirdsql.jdbc.FBConnection conn = (FBConnection)
DriverManager.getConnection("vvvvvvvv");
conn.setTransactionIsolation
(java.sql.Connection.TRANSACTION_READ_COMMITTED);
conn.setTransactionParameters
(java.sql.Connection.TRANSACTION_READ_COMMITTED,new int[]
{org.firebirdsql.jdbc.FirebirdConnection.TPB_READ_COMMITTED,org.fireb
irdsql.jdbc.FirebirdConnection.TPB_REC_VERSION,org.firebirdsql.jdbc.F
irebirdConnection.TPB_NOWAIT});

}
catch(Exception E)
{
JOptionPane.showMessageDialog(null,"ERRO na classe

"
