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: "The interface includes one abstract method—onMessage(Message msg)."

A block of code is set as follows:

public class ClientMDB implements MessageListener { 
 
    @Override 
    public void onMessage(Message msg) { 
        // cast message and process it here 
    } 
 
} 

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

@Inject 
@JMSConnectionFactory("java:app/jms/MyConnectionFactory") 
private JMSContext context; 

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

********* Hello JMS! 

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: "From the Common Tasks pane, navigate to Resources | JMS Resources | Destination Resources"
