GWT deployment on a struts 2 web app

[Tudor Raneti]

Before i go on and try i want to know if it's remotely possible what i want to do.
I have this struts 2 small web app, and i want to display a chart using Google visualization API at the time i'm displaying a table of values from the database (using JSP).
Can i deploy the chart w/o needing the app engine?
Can the chart obtain its data from the Action Context, or from the table itself, or how should i get it?

After some reading, getting data from a database "dynamically" is done through RPC:
http://www.ibm.com/developerworks/opensource/library/os-ad-gwt3/
exploring the other options if needed (HttpRequest, RequestBuilder)

This would be rather helpful when i'm going to need it (and get past the quirks i had):

got an error near the end of the struts2-gwt tutorial:

SEVERE: Servlet.service() for servlet default threw exception
java.lang.ClassNotFoundException: com.google.gwt.user.server.rpc.RemoteServiceServlet

Any thoughts? The tutorial sais not implementinng RemoteServiceServlet for server but make the struts 2 package extend "gwt-default" and use this action:

  <action name="MessageService" class="action.MessageServiceAction"
			method="getMessage">
			<interceptor-ref name="gwt" />
		</action>  

while not implementing an execute() method either on the POJO representing the action. Also it needs moving the compile GWT into WebContent and the ideea is running w/o the GWT embedded Tomcat server (as far the tutorial goes). I'm stuck with it there though.
