Professional JSP (Programmer to Programmer): Amazon.de: Karl Avedal, Danny Ayers, Timothy Briggs: Englische Bücher

Amazon.co.uk

This book explains the inner and outer workings of Java Enterprise Edition's Java Serverside Pages (JSP) as it relates to delivering dynamic Web content. Built on Java Servlets JSP enables Java programmers to produce dynamic Web pages in a manner similar to Microsoft's ASP. JSP has advantages over ASP. For example, it needs to be interpreted only once and runs on server platforms other than Windows.

Professional JSP is a big, dense and full of painstakingly precise technical detail with occasional short illustrative stories. For example; the frog in the well. The eponymous frog is the Java VM. The well is the hardware and OS supporting it. In the story the VM is convinced it has plenty of spare resources but, of course, it can't 'see' the OS on which it runs and thus doesn't realise the support OS has none. The result is a stalled JVM with no problems or errors reported.

No previous knowledge of Java is assumed, though some experience of server programming would help. JSP developers need to understand databases, server administration, HTML and any other technologies with which the servlets interact. In practice, some knowledge of Java is also useful as JSP builds extensively on other Java technologies, JNDI for directory access is one. The case studies demonstrate this well. The weather report example requires working with XLST and WML (for WAP) among other, non-Java, languages.

Considering all this, the section on debugging shows welcome realism, "For a number of different reasons debugging JSP isn't easy". Too right. The combination of new and changing JSP specifications with mutliple languages and technologies makes it hellish. Still, if you persevere with Professional JSP at least you'll be in with a chance. --Steve Patient

For readers with some previous Java experience, Professional JSP is a comprehensive guide to today's JavaServer Pages (JSPs). Besides a solid tutorial on JSPs and servlets, this book gives you lots of useful examples of how JSPs can work with other Java APIs (like EJBs and XML) to deliver highly functional Web sites.

Professional JSP shows the underlying servlet code for many JSP samples. As explained by the authors, JSPs are a simpler way to write servlet code because Java statements are embedded within HTML. This fact makes the book especially useful to programmers who know about servlets and want to progress to JSP development. The introductory tutorial to JSP is as good as any you'll ever see. Short examples illustrate basic JSP features like directives, scripting elements, implicit objects, and JavaBeans. The book also reveals a variety of ways to track session information (including cookies), which is particularly helpful.

Several case studies show key concepts in action, including how to use custom tag libraries. Nicely functional samples include a Web site for an online investment company, a photography database, and a membership-based online grocery store. (This last example shows how to use LDAP and JNDI to store user information.) In addition to a thorough tutorial for learning JSPs, chapters in this text look at combining EJBs, XML, and other Java 2 Enterprise features that you'll need for successful real-world development. Handy appendices detail how to install and configure the free Apache Web Server and Tomcat JSP engine. There's also a reference to all JSP and servlet objects and APIs.

Overall, you'll mine plenty from Professional JSP, including several extremely useful coding examples that'll get you going on serious development for real-world e-commerce Web sites. --Richard Dragan

Highly technical, quite disjointed. 24. Juli 2000

Von Ein Kunde

Format:Taschenbuch

I bought this book after some consideration, but wish i had went for one of the other current JSP books on the market. The problem i find with wrox books is that by having numerous writers, they don't read each other chapters, and consequently repeat each other over and over.

I found this book to be far too big as well. For example, for each JSP example, they print the corresponding servlet code. This takes up a lot of space, particularly in the early chapters and is pretty useless in my opinion. Also there is a glaring typo on the first page of the book which dosnt instill confidence. I think this may be a good book for people already using JSP pages, and looking for extra technical knowledge. However for people like myself, interested in learning how JSPs work and where they fit into server side java solutions, its not the best buy! Its not a bedtime read, one for the office bookshelf.

Overly verbose! 24. Juli 2000

The explanations are too wordy. Please be clear and to-the-point. I am a programmer, I need a JSP book that is clear, concise, and yet advance enough to help me reap the full benefits of JSP technology.

This writting style seems to be the standard of this Stefan Zeiger et al group. Their last "red-covered" book which is "Professional Java Server Programming" is VERBOSE! Each book hit over 800 pages. Is that the goal? Well, the books are keeping me in shape.

I am sorry guys. I am a terrible writer, myself. But when you produce a "Professional" book for programmers, please, put a 110% effort into it.

Good guide to JSP, overlaps with other Wrox titles though 25. Juli 2000

Von David Reilly

For developers involved with web-based projects, whether it be an online store for electronic commerce or an Intranet site for accessing and modifying company data, the powerful blend of JavaServer Pages (JSP) and Enterprise JavaBeans (EJB) technologies can really make life simple. Once you've mastered them, creating new components that encapsulate business logic, or new web interfaces to existing systems, is easy. The trick, for developers, is mastering the technologies.

Professional JSP is one way to get up to speed. Like many of the books published by Wrox Press, Professional JSP covers a specific technology in-depth, as well as the various ancillary topics relating to it such as databases, servlets, and XML. While not every developer will need every web technology covered by the book (and there are many), the book works both as a tutorial to cover the basics and a reference for technologies that you may encounter later.

Professional JSP starts by covering the basics of Java Server Pages, and how they relate to other web technologies. Embedded in HTML pages, JSP provides an easy mechanism for creating interactive web interfaces that draws on server-side components, known as Enterprise JavaBeans. While the presentation logic is written in JSP, the processing occurs within these JavaBean components. The book takes a balanced approach, covering both JSP and its syntax, as well as how to write and interact with JavaBeans to perform useful tasks, like accessing databases through JDBC and using other Java technologies. However, if you've read other Wrox titles, you may find there is some overlap in the topics covered.

One of the nice things about Professional JSP is that, in addition to covering theory, it goes further and examines practical applications of JSP, and issues for programmers like security and debugging. Like other titles in the Professional series, there are case studies of real projects using JSP and related technologies. My favorite would have to be the case study on porting Active Server Pages to JSP -- something that is extremely important for developers with "legacy" web systems. On the whole, Professional JSP is an excellent book for web developers wanting to get up to speed with Java Server Pages, web development, and Enterprise JavaBeans. However, developers with less of a web presentation focus and more of back-end server view may also want to consider the excellent Professional Java Server Programming title, which also covers JSP. -- David Reilly, reviewed for the Java Coffee Break
