Derby EmbeddedDriver and password

[Jose NUNES]

Hi, sorry for my bad English but I'm French. I'm trying to put a 
password on my data base with properties, but good or wrong password 
passes... How can I do ?

My properties :
dbProperties.put("derby.driver","org.apache.derby.jdbc.EmbeddedDriver");
dbProperties.put("derby.url" ,"jdbc:derby:");
dbProperties.put("user" ,"utilisateur");
dbProperties.put("password","123456");
...

Connection dbConnection = DriverManager.getConnection(dbUrl, dbProperties);

Regards
