I've used MySQL in just about every GWT app I've written, so it's quite possible to use it. Including during development running Jetty.
1: All JDBC calls MUST come from the server. The client code can NOT see any jar files, ever. 2: You can NOT reference com.mysql.jdbc.Driver, or any other package that comes from a jar file, in any class that will end up in the client. It doesn't matter if that code is only called from the server. Any class that imports anything from a jar file (or from any of the classes that aren't on the client use whitelist) MUST be in the server package. My guess is that you have one or more classes in *.shared that are importing com.mysql.jdbc.Driver. Move those classes to *.server, or move all the MySQL functionality out of them and into classes that are in *.server.
