Getting error while connecting to MySql db via open source soapUI JDBC step

Hello everyone,

I am getting below error while connecting to MySql DB via JDBC step. I browsed for similar  problems encountered which said check for DB name, where in my case it is correct. Please help. I see from error message, that its hitting DB server IP.

ERROR:java.sql.SQLException: Access denied for user ''@'10.456.99.0' (using password: NO)

Driver: com.mysql.jdbc.Driver
Con string: jdbc:mysql://xxxxx.yyy.abc.com:3640/my_db;user=user&password=xxxx;
