Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Computer programming books often start with a Hello World application."

A block of code is set as follows:

package org.packt.swarm;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

package org.packt.swarm;

import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;

@ApplicationPath("/")
public class HelloWorldApplication extends Application {
}

Any command-line input or output is written as follows:

mvn wildfly-swarm:run

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "we have to click on the Create a route in Services menu of the web console."
