It is entirely possible to basically u...Hey Geoff,<br /><br />It is entirely possible to basically use Grails as a services provider (JSON, XML, whatever) when using GWT.... this came up on the Grails user list recently but the consensus seemed to be that GWT made it too difficult to transform the JSON into complex data to display... but that is only opinion.<br /><br />In our projects we use Value Objects or Data Transfer Objects (check out the Grails DTO plugin for info) which can basically see you recreating your domain objects under src/java/com.company.mayapp.client.These are serializable POJO's that both your server and client can see. This can be seen as an extra layer. Additionally there's the idea of ActionHandlers (see gwt plugin 0.5 release notes) that are designed to delegate from your Grails services to info usable by your GWT client in RPC.... be it DTO's or whatever. This can also be seen as another layer. And using these approaches leave a lot of the logic on the server.<br /><br />Either way has it's positives and negatives... you are either doing most of the work on the server or on the client. So I am not sure if you are gaining too much of a time advantage because you could be just doing in Java on the client what you could be doing in Groovy on the server.<br /><br />One thing I have found is that I only ever really generate Grails Domains and Services these days... there doesn't seem to be a need for controllers when using GWT. Of course this could all change if you are using Grails as a REST provider or something.<br /><br />Hope this helps!<br /><br />@Christophe... we use IDEA for our Grails and GWT dev and it is perfect for the job.johnrellishttps://www.blogger.com/profile/13318765113024624030noreply@blogger.comtag:blogger.com,1999:blog-7369917695391880645.post-65282755046629789622010-06-02T01:45:43.215-07:002010-06-02T01:45:43.215-07:00Is it possible to get this to work in some IDE ?Is it possible to get this to work in some IDE ?cdehttps://www.blogger.com/profile/09263113168316339397noreply@blogger.comtag:blogger.com,1999:blog-7369917695391880645.post-34764114444745692542010-06-01T16:08:05.201-07:002010-06-01T16:08:05.201-07:00Johnrellis: Do you find the GWT + Grails combo is ...Johnrellis: Do you find the GWT + Grails combo is saving you time? One thing that occured to me as I wrote this is that with GWT, most of the Application logic moves to the client, leaving data services on the back end.Geoff Flarityhttps://www.blogger.com/profile/01239564240519036467noreply@blogger.comtag:blogger.com,1999:blog-7369917695391880645.post-35364444877334605942010-06-01T02:09:50.671-07:002010-06-01T02:09:50.671-07:00Good intro...

We have a couple of apps in production using GWT and Grails and for a Java house it is much better than rolling together html & javascript in gsps. IDEA is awesome for GWT support too!<br /><br />Hmmm maybe it is time for some GWT blog posts from me?? We are using smart gwt... not a huge fan to be honest!<br /><br />Thanks for sharing! :)johnrellishttps://www.blogger.com/profile/13318765113024624030noreply@blogger.com
