Examples of com.amazonaws.AmazonClientException

com.amazonaws.AmazonClientException
Base exception class for any errors that occur while attempting to use an AWS client to make service calls to Amazon Web Services. Error responses from services will be handled as AmazonServiceExceptions. This class is primarily for errors that occur when unable to get a response from a service, or when the client is unable to understand a response from a service. For example, if a caller tries to use a client to make a service call, but no network connection is present, an AmazonClientException will be thrown to indicate that the client wasn't able to successfully make the service call, and no information from the service is available. Callers should typically deal with exceptions through AmazonServiceException, which represent error responses returned by services. AmazonServiceException has much more information available for callers to appropriately deal with different types of errors that can occur. @see AmazonServiceException
