I'm thinking about possible alternatives for our EJB based service layer and wondered if it would make sense to use just the service and database layer of Grails together with the Remoting Plugin or is this using a sledgehammer to crack a nut? Speaking of the Remoting Plugin: is there a standard way of generating a JAR file, that conta...
How does the Grails tag fieldValue perform its formatting? I have an domain class with an Double attribute. class Thing { Double numericValue } In GSP, the fieldValue is used (as created by grails generate-all) for rendering: ${fieldValue(bean:thing, field:"numericValue")} Unfortunately digits after 3 decimal places are not di...

In the grails doc, I read (something along the lines) that the implementation of a server class will bu automatically wired based on the naming convention. If this is true, then how would one go about overriding this behavior down the road say if you have a new implementation? do we have options? like: use @annotations if you don't w...

Hi, Lift/Scala is getting a lot of attention lately. Having worked with Grails in the past (and finding it quite handy BTW), I'd like to know if there's anyone who has tried both and what's his/her opinion about them. Is one of them better suited for one kind of scenarios whereas the other is better for other kind, or they compete should...

So is there a 'grails' command that will create new .project (and .classpath and .settings/*) for this source tree? ...
