modeshape-web-example does not show how to get access via JCR API

Found: The first sentence of README.md promises to "show how to get access repository bound in JNDI either via native JCR API or using JNDI API", however:

• RepoServlet.isURI(String) is not invoked anywhere
• All requests are handled by RepoServlet.lookupUsingJndi(String)

main.jsp makes similar statements as README.md.

Expected: README.md, main.jsp and RepoServlet should match each other. If there are more options, please explain how they differ and which one should be preferred under which circumstances.
