Grails Deployment on Openshift

Just a simple guide on how to get started on deploying a Grails app up to Openshift.

The prerequisites to get started, we need two things being Git and the Openshift RHC tool.
Guide on how to install them in different OS platforms are available here.

This is only a simple static website developed using Grails. This guide is based off on

Step 1:
Don't bother creating the free app on the Openshift application console. Instead we're gonna use the Openshift RHC command line tool and create the free app. Do this in your user directory:

rhc create-app appname tomcat-7

This will create a gear that is assumed to be Jboss EWS 2.0, but it's not.

Anyways, assuming that you're not doing any data storing functionality on the Grails app, tomcat-7 is what you need.

So let everything being taken cared of for you, and a repo will be cloned based on the appname that you've put.

Step 2:
Generate a war file out of your Grails project by using this command
grails war

Rename the war file generated from Grails to ROOT.war and dump it into appname/webapp folder.

Step 3:
Inside the cloned appname folder, open up
.openshift/config/servers.xml

set unpackWars to true

 Step 5:
Delete pom.xml file somewhere in the src folder within the appname folder.

Step 6:
In the appname git root folder directory

git add .
git commit -am 'first commit'
git push


Step 7:
Sit back, relax and drink beer. (Kidding...)
Wait for a while because it's gonna need a few minutes for the deployment to take effect.

How to Utilize the onUpgrade method in your SqliteOpenHelper Class in Android

Based on this website's blogpost on how to non-destructively upgrade your Android app's database , I've encountered a scenario such as this: 1. I have a database which has a database version 1 which has an existing table being constructed in user's phones. 2. If I were to have a new column in my database table, if I were to deploy the new version of the app into the Google Play Store (what I mean here is an incremental install), of course I would have users bitching about force closes in my app because the database is altered, for instance by adding another column in my database table. The blogpost is helpful as he highlighted how database table alteration can be done by incrementing the database version and onUpgrade method is triggered in your SqliteOpenHelper class.
