I use the SimpleTemplateEngine to create my email bodies in this fashion: def ccIdToEmailMap = [:] def emailTemplateFile = Utilities.retrieveFile("email${File.separator}emailTemplate.gtpl") def engine = new SimpleTemplateEngine() def clientContacts = ClientContact.list() for(...
Is there a way (in Grails) to change the 'primary' database while the application is running, but before any domain objects have been instantiated? I'm trying to set up an app where each customer has their own database, but don't want to have to run a separate Java interpreter for every single customer. ...

If I have two separate Grails apps running on the same app server (Tomcat/Glassfish), how do I allow the user to log into the first app then have him authenticated for the second app so he's not prompted when he goes to that app? ...
Can someone tell me why this Grails domain class will not compile (at runtime)? class Person { String name String getSomething(int i) { } } I get this error when I run with grails run-app: 2008-12-27 15:26:33.955::WARN: Failed startup of context org.mortbay.jetty.webapp.WebAppContext@187e184{/asrs2,C:\Steve\asrs2/web-ap...
How can I reference a Groovy domain class from Java class using Eclipse? I've put my domain class in package: package com.me.myproject public class Person { String name int age } Then in my Java class I attempt to reference com.me.myproject.Person. This works for grails run-app (command line) but not Eclipse. Eclipse can't re...
I did a grails clean and afterwards when I run via grails run-app the app never starts and the following is repeatedly displayed (goes on forever, stuck in some kind of loop). I'm running Grails 1.0.4, Java 1.6 on Windows XP. Grails is somehow stuck in an invalid configuration. Any idea how to restore it? [groovyc] Compiling 3 sourc...
I have the Grails domain classes Child and Toy. A child can have many toys. class Child { static hasMany = [ toys : Toy ] String name } class Toy { static belongsTo = [ owner : Child ] String name } It was my understanding that there will be a toys property on Child. That is, there will be the Child method: public Se...
Hi there, I'm trying to craete a site which allows users to upload any file type they like. I've implemented this feature fine, and the file is held on the server. Later on they can download the file to view, but i'm having trouble getting it to work. I've used any examples I can get hold of but they all tend to use text files as examp...
I have the domain classes: class Child { static hasMany = [ toys : Toy ] String name Set toys } class Toy { static belongsTo = [ owner : Child ] String name } In my JSP I reference a child by: child = Child.findByName("Joe") or child = Child.findById(123) But when I attempt to access its fields: child.getTo...

This is half rant, half question. Is it worth using Grails? I'm trying to develop a relatively simple database drive web applications. My expertise is in Java so naturally Grails seemed like a good choice. At first I thought of using Spring, JPA and Hibernate, but having used that previously I've ran into all sorts of tedious configurat...
I have a Grails application with a JSP page (I'm porting a legacy JSP application). For some reason, the page renders completely blank. Looking at the HTTP headers I see it's 200 with a content length of 0. HTTP/1.1 200 OK Content-Language: en-US Content-Type: text/html; charset=iso-8859-1 Expires: Thu, 01 Jan 1970 00:00:00 GMT Set-Cook...
So it looks like Grails' GSP does not have an include tag (correct me if I'm wrong). The closest thing to "include" is to use the render tag. There is also the include plugin. In my case, I have a classic top-left-middle-right-bottom paned page. The top header or left side would include navigation. The middle would be the content. The r...

Has anybody tried doing GSP design with Adobe Dreamweaver CS4? It has support for JSPs, but it doesn't recognize the gsp extension, and even if it did I think there would be problems regarding the gsp tags that it would not recognize. I found a little cookbook here (http://www.bitwalker.nl/blog/using-groovyserver-pages-in-dreamweaver) fo...
