lcm-jms-helloworld

A simple example of using Java Message Service (JMS) for sending and receiving messages to/from a queue.

The project contains two classes, each with its own main method.

HelloWorldActiveMQ.java demonstrates how to use JMS with ActiveMQ. Please refer to JMS_HelloWorld.pdf or JMS_HelloWorld.docx for more documentation on this example.

HelloWorldSQS.java demonstrates how to use JMS with AWS SQS (Amazon Web Services - Simple Queue Service). The main method first connects to SQS, then sends a text message, receives a text message, and finally closes the connection. To get the example running, two things have to be prepared:

• Add your AWS API credentials, the access key and the secret key, to src/main/resources/aws.properties (you may use aws.properties.example as a template)
  Note: Do not rename aws.properties.example to aws.properties but rather create a new file named aws.properties instead.
  Otherwise, Git will no longer ignore the file, possibly resulting in your AWS credentials being committed and pushed and available to everyone.
• Create a SQS queue, e.g. using the AWS console, and then adjust private static final String queueName = "..." accordingly (HelloWorldSQS.java, line 41)
