Conventions

In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

There are three styles for code. Code words in text are shown as follows: "A managed-data-source element is added to the data-sources.xml file."

A block of code will be set as follows:

<resource-ref>
<res-ref-name>jdbc/OracleDataSource</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>

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

CREATE TABLE OE.Catalog(Journal VARCHAR(25), Publisher Varchar(25), Edition VARCHAR(25), Title Varchar(45), Author Varchar(25)); 

New terms and important words are introduced in a bold-type font. Words that you see on the screen, in menus or dialog boxes for example, appear in our text like this: " In the Create Project window specify a Project Name and click on Next".
