Bonjour,
Tu fais :
String sql="select user from sys where user_id= ahlam and password=halouma1";
pst=(OraclePreparedStatement) conn.prepareStatement(sql);
pst.setString(1, user_id.getText());
pst.setString(2, Password.getText());
Si tu veux paramétriser ta requête avec setString il faudrait que tu ajoutes des ? dans ta requête, pour remplacer les valeurs en dur que tu as mis.
String sql="select user from sys where user_id= ? and password = ?";
