on another database my java work fine and able connect. seems to be an issue at database level ?! what I need to fix at database level ?

adding the code of the connection:

public Connection getConnection() {     
    try {
        Class.forName(jdbcDriver);

        connection = DriverManager.getConnection(connectionString());
    }
    catch(Exception ex) {
        ex.printStackTrace();
        logger.error("Exception:" + ex.getMessage());
        errorMessage = ex.getMessage();
    }

    return connection;
}

where:

jdbc:mysql://127.0.0.1:3306/db?user=gda&password=gda

i don't know i get this credentials from our dba, i guess he changed the root password — Dumitru Gutu, Apr 15 '15 at 13:57

I had a similar issue but with php. Instead of using `localhost`, try using `127.0.0.1`, that worked for me. — Jacob Lambert, Apr 15 '15 at 14:03
from command line work with that password, same i use in the java code — Dumitru Gutu, Apr 15 '15 at 14:05
for 127.0.0.1 i get com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server. — Dumitru Gutu, Apr 15 '15 at 14:07

Try to pass the username and password in this manner:

String DB_URL = "jdbc:mysql://localhost/xyz";
String USER = "username";
String PASS = "password";

conn = DriverManager.getConnection(DB_URL,USER,PASS);

I doubt that this will fix the problem, perhaps it should be posted as a comment? – Magnilex Apr 15 '15 at 14:45
if not address the issue, I think its worth a try. – Mecon Apr 15 '15 at 14:59
tried but does not work, i created a new user and was able to connect using old java code. so it's something wrong with user at database level. I addressed this to our dba – Dumitru Gutu Apr 15 '15 at 15:46
