If you wanna make a GAE app you can't use mysql. If you wanna do a GWT

The solution if you want to use a database connection ( MySQL for example)
:
1 - You can't use google app engine mode (enable by default on Eclipse with
GWT plugin) : To disable the google App mode : right click on the project
Google App setting engine uncheck use google app engine

Are there otherways just to exclude GAE and switch to another server,

Is there a good howto available how to use tomcat or others instead of

Does your project use Google App Engine? Cause GAE plugin works as a sandbox
and doesn't allow to make arbitrary network connections (

Actually, what you HAVE to do is ask your server to get the data from your
database, whether that is RPC, or FormPost or HTTP GET or some form of XHR is
really a decision for you to make based upon your server technology. GWT
doesn't really care.
As for accessing MySQL, that is a problem more

If you are using Google App Engine (separate from GWT), you *cannot* use an
external database. App Engine doesn't allow you to open socket connections,
and that is exactly what the getConnection() method does.

Hi,
The problem is that you're trying to mix GWT and java.sql. That's not
going to work. JS in the browser can't connect to your database.
The cause of your specific error is that Class.forName() is not a part
of the JRE that GWT emulates.

Can you guys point in the direction of either a concept on how I would
