Re: GWT Spring integration - what is the best method in late 2010?
Great I will take a look. This area of GWT is moving pretty fast. A couple the projects mentioned by David are new to us since we have started development including gwt-platform. We like gwt-dispatch but we are crazy about the number for little libraries we are using for the full stack. gwt-platform looks like a option to bring those together.

Re: GWT Spring integration - what is the best method in late 2010?
I took a brief look at gwt-platform. I didn't see examples where the GWT 2.0 UI binding capability is used. We are successfully using this with Gin. Do you know of examples that include the use of UI Binder?

Re: GWT Spring integration - what is the best method in late 2010?
I honestly can't weigh in on all of these framesworks. Gwt-dispatch is maintained and is pretty light weight and extensible which we have extended ourselves to add Spring support. Looks like the latest version adds that in for anyone needing it. We have also extended it to lessen the burden of creating new GWT-RPC end points. We use an annotation based approach that basically adds a new Gwt-Dispatch action handler which equates to a new GWT-RPC endpoint. Our current production code base is using Spring 3.x and Gwt-Dispatch 1.0.0.

Re: GWT and MCV
MVC isn't ideal for rich client applications that are heavily event oriented. Too much ceremony for not a lot of value add to that testability is harder with MVC. With MVP you can get near 100% coverage by having everything in the presenter and keep to the practice of the View only holds UI widget state and handles events that then proxies calls to the Presenter. Don't get trapped in best practice methods when another solution might be better for a different software paradigm like GWT. MVC works really well for back end frameworks like JSF, Wicket, or Struts that are not so event based. Make sure to check out the Google I/O GWT best practices video. http://code.google.com/events/io/2009/sessions/GoogleWebToolkitBestPractices.html On Fri, Sep 24, 2010 at 9:32 AM, Foued Elguenbri wrote: > you can use GWT+GXT, the framework implements MVC. > if you talk about the hole application MVC, it is simple you link the GWT > services with your core services using spring and gwt-dispatcher. > > http://code.google.com/p/gwt-dispatch/ > -- > Cordialement. > Foued ElGuenbri * Java/JEE Architect - Senior Developer * SunGard > Technology Services* Centre Urbain Nord -Charguia 1 BP130 1082 Tunis Tunisia > * > > > 2010/9/20 CoDe > > Hi there!! exist some way of integrate gwt with some framework mcv? >> >> Thx, >> Jorge >> >> -- >> You received this message because you are subscribed to the Google Groups >> "Google Web Toolkit" group. >> To post to this group, send email to google-web-tool...@googlegroups.com. >> To unsubscribe from this group, send email to >> google-web-toolkit+unsubscr...@googlegroups.com >> . >> For more options, visit this group at >> http://groups.google.com/group/google-web-toolkit?hl=en. >> >> > -- > You received this message because you are subscribed to the Google Groups > "Google Web Toolkit" group. > To post to this group, send email to google-web-tool...@googlegroups.com. > To unsubscribe from this group, send email to > google-web-toolkit+unsubscr...@googlegroups.com > . > For more options, visit this group at > http://groups.google.com/group/google-web-toolkit?hl=en. > -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: GWT Spring integration - what is the best method in late 2010?
Hey lalit, I will take a look at this further this was and example of how to implement Spring on a previous version and is basically the servlet example class I posted earlier. I will take a look at the newer version of gwt-dispatch to see what else has been included. We were waiting on upgrading but this peaks my interested on upgrading sooner. WebApplication context is just Spring's way of bootstrapping an application context in a web container. What that class does is grab the application context wires in the DispatchServlet so POJOS can be injected in to all the classes it supports. Definitely it is in the spring-web jar but it appears that is the only Spring feature gwt-dispatch project takes advantage of. If you take a look at the ActionHandler and base dispatch classes you don't see any other Springy stuff. Gwt-dispatch helps us to avoid having to code the separate interfaces. We just code actions, action handlers, and result objects. All the dispatch traffic routes through the one GWT-RPC service that gwt-dispatch implements. All the async workings have to be there but, we get to work on valuable object interactions and avoid ceremonial grunt work which always makes coding more fun.

Re: GWT Spring integration - what is the best method in late 2010?
Lalit we are not using Spring MVC. We am using gwt-dispatch and have extended that project's dispatch servlet to get the Spring integration. We then added a custom annotation to pick up the appropriate dispatch action handler for a particular GWT-RPC on the server side. All of our GWT-RPC calls go through this servlet so we avoid the overhead and code bloat of having to create the standard GWT-RPC interfaces for every new service call we want to implement. I looked over your example again and they are pretty similar. I like your integration approach with Spring but I prefer service call handling because we don't have to code the two separate RPC interfaces, i.e. the Service and ServiceAsync for every service we want to implement. We just create an new dispatch handler apply an annotation to it and we are off and running.

Re: GWT Spring integration - what is the best method in late 2010?
I would highly suggest going back to my recommendation, lalit's idea is good but, my example is more complete, takes less effort to implement and is easier to extend. Especially with the use of gwt-dispatch and implementation of a GWT architecture pattern implementation from the Google I/O talk on GWT from the last session.

Re: GWT Spring integration - what is the best method in late 2010?
We haven't used gwt-spring. We are using gwt-dispatch with an
implementation of their DispatchService interface and a subclass of the GWT
RemoteServiceServlet class. We have had no issues with this. Then just had
this servlet in like you would any other.
It looks like this:
public class StandardDispatchServiceServlet extends RemoteServiceServlet
implements DispatchService {
private static final long serialVersionUID = 1L;
private Dispatch dispatch;
@Override
public void init(ServletConfig config) throws ServletException {
super.init(config);
WebApplicationContext applicationContext =
WebApplicationContextUtils.getRequiredWebApplicationContext(config.getServletContext());
AutowireCapableBeanFactory beanFactory =
applicationContext.getAutowireCapableBeanFactory();
beanFactory.autowireBean(this);
}
public Result execute(Action action) throws ActionException {
try {
HttpServletRequest request = getThreadLocalRequest();
BaseDispatchCommand cmd = (BaseDispatchCommand)action;
cmd.setHost(request.getLocalAddr());
cmd.setPort(request.getLocalPort() + "");
cmd.setUrlContext(request.getContextPath());
if(cmd.isSerializationRequired()){
//only allow 1 synchronized required request to execute at a time
//requires a session to have already been generated
synchronized(request.getSession(true).getId().intern()){
return dispatch.execute(action);
}
} else {
return dispatch.execute(action);
}
} catch (RuntimeException e) {
log("Exception while executing " + action.getClass().getName() +
": " + e.getMessage(), e);
throw e;
}
}
@Autowired
@Required
public void setDispatch(Dispatch dispatch) {
this.dispatch = dispatch;
}
}
Hopefully this is an option for you.

Re: Using Oracle and Hibernate in Google Web Toolkit's Hosted Mode.
keyboard-samurai I would highly recommend you check out the Google I/O GWT Best Practices <http://www.youtube.com/watch?v=PDuhR18-EdM> video. It talks about gwt-dispatch and MVP. You will want to implement your connections to Oracle/Hibernate in the GWT-RPC servlets. The project I am on we are using our own extension of the gwt-dispatch project's servlet to initialize a Spring context. Our web.xml looks like this: contextConfigLocation classpath:applicationContext.xml org.springframework.web.context.ContextLoaderListener dispatchServlet com.own.custom.extended.server.StandardDispatchServiceServlet dispatchServlet /client/dispatch Our applicationContext.xml sits in the WEB-INF/classes directory. Nothing but standard Spring stuff there including the necessary things to get Hibernate working. If you want to skip Spring I am not going to be of much help there but, I am sure it can be done.

Re: Rounded Corners with UIBinder
Take a look at the DecoratorPanel. It implements a 9-box and you should be
able to use css to override the defaults.

You will get that with just GWT.

GWT/Hibernate/Oracle/Eclipse
Read the developer's guide :). There is a white list of classes for both Google App Engine and Web Tool Kit. You have run into that restriction. You will probably have issues with trying to use Hibernate. If you are using Google App Engine you will have to you use App Engine's JDO or JPA implementations. If you want to use Hibernate then remove the App Engine from the design. Jas -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
