Off-Topic: Groovy and Grails on Raspberry Pi

It works! Received my Raspberry Pi this week and had to see if it runs Java, Groovy and Grails.

The ressources (256MB memory) of the Raspberry are very limited, so I didn't really expect to make it work, but instead it was easy.

a simple

apt-get install openjdk-7-jdk

installs java. The same for groovy:

apt-get install groovy

It takes some seconds until the groovy shell starts up, but it makes a good impression.

Installing Grails was a little bit harder since it can't be installed through apt-get. But a

wget http://dist.springframework.org.s3.amazonaws.com/release/GRAILS/grails-2.0.4.zip
unzip grails-2.0.4.zip

nearly did the job. You still have to set some environment variables and lower the memory needs through GROOVY_OPTS (I personally changed the settings directy in the startGroovy). After that it works! Slowly, but it works. Generating a page takes aprox 6 minutes :-)
