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.

Code words in text are shown as follows: "The Catalog entity bean has properties id and journal".

A block of code is set as follows:

@Resources({
@Resource(name="ds1", type="javax.sql.DataSource"),
@Resource(name="ds2", type="javax.sql.DataSource")
})

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "In the New Gallery window, select Categories:General | XML and Items:XSL Style Sheet and click on OK".
