Access denied when trying to access MySql through connector J and Servlet

I am trying to connect to MySQL (most current version) db through a java servlet.
The error message I get is this: Error: java.sql.SQLException: Access denied for user ''@'localhost' (using password: NO)

The setup-driver string I am using is this:
com.mysql.jdbc.Driver
jdbc:mysql://localhost:3306/iap_local?user=root&password=belcanto

The servlet runs under Tomcat (5), and the driver file is installed in the Tomcat directory under the shared/lib folder.

These settings work (allow access) when using MySQL from the command line, but also work using Navicat (GUI for M ySQL).  

The intended use is for an expert system (Exsys Corvid) to be able to access the database on my local machine.  We have it working fine on a remote  internet hosting machine, but cannot get it working locally.  
I know just enough about java etc to be dangerous!

The error you are getting suggests that it is not connecting as the "root" user.  Either your Java code is trying to connect using a different connection string than the one you've posted here, or the user name and password aren't correct.  Given that you can connect using the command line with this user name and password, it seems likely that the former is true.  Perhaps you can provide some of the relevent Java code for us to look at?

Todd,

Thank you for your answer.  I think I have ascertained that my vendors servlet was incompatible with the newer version of MySQL I loaded to run the app locally.  When I used their "old" driver (the org:gjt.mm etc...) the querry worked OK.  I will now nag them to update their system to run with the new MYSQL!

But your answer (the connection string) was right on track...

Thanks.   Hope you enjoy the points, what ever you can do with them.
