Creating an Image Resizing Application

The first time I try to run something, it doesn’t work… surprise, surprise…

Anyway… I look online and it says that all the credentials should have been picked up from when I setup the CLI (Command Line Interface). I checked in Eclipse via Window > Preferences > AWS Toolkit, and it all seemed fine. I did set up a profile of awsdeveloper because I wanted to keep it separate from work aws stuff.

Unable to find a region via the region provider chain. Must provide an explicit region in the builder or setup environment to supply a region. at com.amazonaws.client.builder.AwsClientBuilder.setRegion(AwsClientBuilder.java:436)#

Found the answer in the first stackoverflow question Google found:

“I solved this by adding the AWS_REGION environment variable. E.g. us-east-2. When using Eclipse, you can add this using the Run –> Run Configurations.”

As I was running a JUnit test, I updated the Debug Configuration. 😀

I have been a software developer since 2004 and have worked in many different languages. I started off using scripting languages on the web and transitioned into Enterprise Java development. I have worked as a Team Leader and independent contractor in this capacity. I then decided to take a break, before changing direction to create apps for mobile devices. I changed languages and focused more on the business and design side of things for a while. However, I'm getting pretty jaded by the new and shiny, so I am going back to what I know best and retraining in all the new Java ways and really enjoying the process. My Java 8 certification was the start, this blog will tell the rest of the story.
