Websphere Liberty and AWS SQS Integration

Andrea_rodriquez

I have been trying to access aws sqs from websphere liberty using jndi. I have followed the instructions given in this link https://developer.ibm.com/wasdev/blog/2017/08/15/configuring-websphere-liberty-use-amazon-simple-queue-service/

But I am getting the following error.

Cannot create initial context

To access AWS SQS from WebSphere Liberty using JNDI, you need to add the following to your server.xml:

For more information, see the WebSphere Liberty Knowledge Center:

Accessing AWS SQS using JNDI in WebSphere Liberty is quite straightforward. All you need to do is configure a connection factory in Liberty's server.xml. To do this, you will need to supply the URL to the AWS SQS queue, authentication credentials and required libraries.

First, create a file called jms.properties. You should include the SQS queue URL in this file, as well as your AWS Access Key ID and Secret Access Key. This is the authentication information for your AWS account.

Next, configure your Liberty server.xml file to include the connection factory. This is where you add the jms.properties configuration, as well as specify the class name for your JMS connection factory and any other required JMS resources.

Finally, configure your Liberty server.xml file to include the correct libraries. The following libraries are required:jms-2.0.jar, aws.sdk-1.11.478.jar, aws-sqs-client-1.10.68.jar and commons-httpclient-3.1.jar.

Once you've done this, you should be able to access your AWS SQS queue from WebSphere Liberty using JNDI.
