The first six lines in the previous screenshot are logger messages (warning, information,
or error) and the remaining lines are the output syso (short way of calling
Sys-
tem.out.println
) print statements mentioned in the sample code.
I have deliberately modified the access key of the credentials file located at
$USER_HOME/.aws/config
. After that, if we try running the sample code it will
throw the error
UnrecognizedClientException
.
This exception will be thrown only if the project is not able to instantiate the DynamoDB
client, which is a clear indication that there is something wrong with the credentials. Take
a look at the following screenshot:
Since the sample code is provided by AWS itself, I don't want to get into trouble by
providing the code here. So we will see what that sample code does. First and foremost, it
creates a table named
my-favorite-movies-table
in the
US_WEST_2
region.
Once we have run this code, we need to open AWS Explorer and refresh Amazon Dy-
namoDB as follows:
Tip
Make sure that you've selected the correct region (
US_WEST_2
) in AWS Explorer; other-
wise we cannot see the table getting created.
