JSTL 1.0, EJB 2.1 and XML Basics

ONJava Newsletter for 08/15/2002

Dear Reader,

The future of JSP development is here, and its name is the JSP Standard Tag Library. JSTL provides a set of standardized JSP custom actions to handle the tasks needed in almost all JSP pages, including conditional pro- cessing, internationalization, database access, and XML processing. This week on ONJava.com, Hans Bergsten, author of O'Reilly's "JavaServer Pages, 2nd Edition," starts a series of articles on the new JSTL specification. This article gives an overview of JSTL and shows how to use the most common JSTL actions.

Also this week, ONJava.com's new EJB columnist, Emmanuel Proulx of BEA Systems, covers what's new in the Enterprise JavaBeans (EJB) 2.1 draft specification. If you want to know what the future has in store for EJBs but don't have the time to read a 636-page document, Emmanuel's first article offers a quick overview. Specifically, it focuses on the updates to message-driven beans and the query language (EJB-QL), as well as new support for Web services.

And finally this week, there's part five in a series of book excerpts on XML basics for Java programmers from O'Reilly's "Learning Java, 2nd Edition." This week's excerpt offers a quick introduction to XSL/XSLT and Web services.
