There are several issues that need to be address with regard to the documentation surrounding the simplest of the 3 JAX-RS examples.
The sentence that precedes 220.127.116.11 needs to be modified to say something to the effect that the prebuilt example is similar but not identical to the example that one can build from the archetype. There should also be links to new sections for running that prebuilt example with NetBeans IDE and Maven from the command line.
There needs to be a step 0 that says "Ensure that you have installed the tutorial archetypes as described in Section 2.7.1, Installing the Tutorial Archetypes.
Step 1d needs to be changed from "... and click Next." to "... and click Finish."
Step 1e needs to be deleted.
In step 2, delete "and the exception".
In step 2, move the Note so that it follows the code example.
In step 3, change "hello project" to "HelloWorldApplication project" and change "Build" to "Run".
In step 4, change the URL from "http://localhost:8080/hello" to "http://localhost:8080/HelloWorldApplication/HelloWorldApplication".
Add a new section - 18.104.22.168, To Run the hello Example with NetBeans IDE.
Add a new section - 22.214.171.124, To Run the hello Example with Maven.
Make sure the instructions match the prebuilt example. For example, the URL to open would be http://localhost:8080/hello/helloworld.
