This is a demo application built with MicroProfile and currently running setup to run on OpenLiberty. It will return a combination of a random adjective and a noun.
The generation of the executable jar file can be performed by issuing the following command:
mvn clean package
This will create an executable jar file `randomstrings.jar within the target maven folder. This can be started by executing the following command:
java -jar target/randomstrings.jar
To launch the test page, open your browser at the following URL
http://localhost:9080/index.html
See the website for more information on MicroProfile.
