You are getting this exception because your AWS SDK is unable to load your credentials  What you should do is goto Preferences then goto AWS and add your secret key and access key  So that your project can retrieve both keys

In a Linux server  using default implementation of ses will expect files in  aws credentials file  You can put following content in credential file at the location below and it will work   home local  lt your service account gt   aws credentials    default  aws access key id  lt your access key gt  aws secret access key  lt your secret access key gt

If you use the credential file at    aws credentials and use the default profile as below    default  aws access key id  lt your access key gt  aws secret access key  lt your secret access key gt    You do not need to use BasicAWSCredential or AWSCredentialsProvider  The SDK can pick up the credentials from the default profile  just by initializing the client object with the default constructor  Example below   AmazonEC2Client ec2Client   new AmazonEC2Client      In addition sometime you would need to initialize the client with the ClientConfiguration to provide proxy settings etc  Example below   ClientConfiguration clientConfiguration   new ClientConfiguration    clientConfiguration setProxyHost  proxyhost    clientConfiguration setProxyPort proxyport   AmazonEC2Client ec2Client   new AmazonEC2Client clientConfiguration

There are many correct answer above   Specifically in Windows  when you don t have    aws  folder exist and you need to create the new one  it turned out to be another problem  meaning if you just type   aws  as name  it will error out and will not allow you create the folder with name   aws    Here is trick to overcome that  i e  type in   aws   meaning dot at the start and dot at the end  Then only windows will accept the name  This has happened with me  so providing an answer here  SO that it may be helpful to others

You can use DefaultAwsCredentialsProviderChain    which according to the documentation  looks for credentials in this order    Environment Variables - AWS ACCESS KEY ID and AWS SECRET ACCESS KEY  recommended since they are recognized by all AWS SDKs and CLI except for  NET   or AWS ACCESS KEY and AWS SECRET KEY  only recognized by the Java SDK  Java System Properties - aws accessKeyId and aws secretKey Credential profiles file at the default location     aws credentials  shared by all AWS SDKs and the AWS CLI Instance profile credentials delivered through the Amazon EC2 metadata service

If you re wanting to use Environment variables using apache tomcat  I found that the only way they could be found was setting them in tomcat bin setenv sh  where catalina opts are set - might be catalina sh in your setup   export AWS ACCESS KEY ID             export AWS SECRET ACCESS KEY                  If you re using ubuntu  try logging in as ubuntu  printenv then log in as root  printenv  the environmental variables won t necessarily be the same      If you only want to use environmental variables you can use  com amazonaws auth EnvironmentVariableCredentialsProvider  instead of   com amazonaws auth DefaultAWSCredentialsProviderChain   which by default checks all 4 possible locations   anyway after hours of trying to figure out why my environmental variables weren t being found   this worked for me
