The servlet cannot establish a connection to the database, it tells authentication failed, are you sure, you are giving the correct credentials?

We make this application some modifications as client requested that he don't want to enter user name and password then we remove that one give access to application directly.
It works fine in all systems but when we try it in a new laptop it is shoeing this error
