Installation & Hallo world on Ubuntu 13.10

[janvesely]

Hi Everyone,

First of all, I am new to Grails and new to Linux. I did try to follow all the manuals/instructions as specified but failed to get a webapp up&running.

My computer:
Ubuntu: 13.10 (the latest)
Java: java version "1.7.0_25", OpenJDK Runtime Environment (IcedTea 2.3.12) (7u25-2.3.12-4ubuntu3), OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode)

Ok, GRAILS installation
1. I followed Ubuntu specific instructions as specified here: http://grails.org/download/ubuntu
... and failed in step 3: sudo apt-get install grails-ppa
E: Unable to locate package grails-ppa

2. I tried to install Grails using gvm and managed to get latest Grails on my machine.
3. create-app and create-controller worked, I used the very simple example

def index() { 
		render "Hi"
	}

4. When I attempted to run the application using run-app, all hell broke loose about hibernateProperties (cannot resolve reference to bean) and some other fine stacktraces.

Different approach
1. I installed Grails Tool Suite from Springsource
2. The GTS comes with Grails 2.24
3. I created a new app and new controller, added the same "high-tech" code for hallo world as above
4. I selected "Run as->Grails command: run-app"
....and got flooded with stracktrace about hibernate properties and hibernate dialect (full stacktrace below).

Ok, I know Java, JEE and Hibernate. In the book I read about Grails (unless I am wrong) the author wrote that development environment just uses in memory database by default and all should work out of the box. However, when I look at the stacktrace, it does seem as if some configuration is needed. As a noob, my question is - what needs to be configured where?
