In your host page add something like this:
<script type="text/javascript">
var modules = {start:"module-name"};
</script>
You can use it as a Dictionary
http://google-web-toolkit.googlecode.com/svn/javadoc/2.0/com/google/gwt/i18n/client/Dictionary.htmlfrom
your GWT code.
>From my point of view, I still don't understand, why you have to deal with
two different pages. A GWT application is a real client application. It is
started, when the host page loads and it is shut down, when you leave the
page (e. g. you're going to a different URL). In a well designed GWT
application, you should make the registration module a part of your
application and send the entered data through an Ajax request to the server
in the background. This would prevent you from shutting down your
application for registration and start it again after registration is done.
The other point is, that JSPs might be easier to handle than servlets for
realizing the host page on the server. So use the JSP as your welcome file.
