This is a book about computer programming for everyone: artist, poet, student, doctor, accountant, or engineer. This book will show students how to write understandable computer programs in Java. While emphasizing general principles of programming this book: - uses examples from the humanities only, requiring no math or engineering knowledge -explains all programming concepts by means of complete programs -concentrates on exercises solved by writing complete programs -takes the reader from text input/output to object-oriented programming in the equivalent of a one semester class. -gives the reader a solid background for follow-on courses on the graphics and networking facilities of Java. This book is a sound and complete introduction to programming. Although the book uses Java, the same methods can be used for systematic programming in other languages, such as C, Fortran, and Pascal.

"J2EE FrontEnd Technologies: A Programmer's Guide to Servlets, JavaServer Pages, and Enterprise JavaBeans" concisely and accurately describes what you need to know about effective enterprise development based on servlets, JSPs, and EJBs. Servlets, JSPs, and EJBs are the most important aspects of Java as it is used in the production of enterprise Web applications today. Lennart Jorelid 's book concentrates on teaching programmers how to fit the various technologies together while spending as little time as possible on "plumbing."

Jorelid discusses servlet development and architecture, and he teaches developers how to integrate servlets into distributed enterprise systems with illustrated examples. He explains the architecture and implementation of JSPsincluding introductory concepts such as using all built-in facilities of the JSP library and advanced topics such as creating your own custom actions using the JSP Tag Library API.

Jorelid also addresses the open-source Struts framework from the Apache Software Foundation, which provides a powerful framework for J2EE Web application development by combining servlets and JSPs. And, finally, Jorelid explores the EJB programming paradigm, covering development and architecture of EJBs and J2EE integration and deployment.

"J2EE FrontEnd Technologies: A Programmer's Guide to Servlets, JavaServer Pages, and Enterprise JavaBeans" provides developers with a unique approach to understanding the profound relationship between servlets, JSPs, and EJBs. Developers will gain a clear understanding of all three and will be able to harness this knowledge for their own real-world applications.

Das Buch zeigt, welche Potentiale sich f r Unternehmen durch eine konsequente Orientierung an den Kundenprozessen und einer kooperativen Zusammenarbeit zwischen Unternehmen ergeben. Eine wichtige Rolle nehmen dabei elektronische Dienstleister (sogenannte WebService-Anbieter) ein, die diese Kooperationsprozesse erst erm glichen oder die elektronischen Services viel effizienter erbringen als jedes einzelne Unternehmen im Netzwerkverbund, z.B. f r den Zahlungsverkehr und die Logistik. Dazu werden anhand anschaulicher Beispiele aus der Praxis methodische Vorschl ge zur Gestaltung des Kundenprozesses, zum Portaldesign und zur Kooperationsprozessanalyse und Out-tasking sowie Architekturen f r Kooperationsprozesse und WebServices entwickelt.

"Architecting Web Services" is targeted toward developers and technical architects who have heard about, and even started to work with, Web services. The book starts with a background on the evolution of Web services and their significance to future collaborative efforts via the Internet. It then reveals the architecture for Web services and the various relationships that can be established through their consumption.

Following a short technical primer on XML and related technologies, the Web services model is outlined to illustrate the decisions that have to be made in the areas of presentation, interface, and security before the design is even started. Topics ranging from content to state management to system infrastructures are discussed to help you understand the options and the pitfalls when developing robust Web services.

The life cycle of implementing Web services from start to finish is illustrated, taking existing processes and exposing their functionality through Web services. Examples extend both Java and COM objects as Web services before exposing an entire hotel reservation system through a Web services workflow. These exercises are followed by three application scenarios that consume these Web services, again with both Java and Visual Basic/ASP examples. Discussions cover the design, implementation, and testing of each solution to ensure a successful result.

Finally, the book takes a look ahead at the future of Web services by examining both the current strategies of the primary vendors and the standards initiatives that are presently under way. A companion website provides all the source code, and hosts the Web services and sample applications introduced in the book.

Introduction to Modeling and Simulation with MATLAB and Python is intended for students and professionals in science, social science, and engineering that wish to learn the principles of computer modeling, as well as basic programming skills. The book content focuses on meeting a set of basic modeling and simulation competencies that were developed as part of several National Science Foundation grants. Even though computer science students are much more expert programmers, they are not often given the opportunity to see how those skills are being applied to solve complex science and engineering problems and may also not be aware of the libraries used by scientists to create those models. The book interleaves chapters on modeling concepts and related exercises with programming concepts and exercises. The authors start with an introduction to modeling and its importance to current practices in the sciences and engineering. They introduce each of the programming environments and the syntax used to represent variables and compute mathematical equations and functions. As students gain more programming expertise, the authors return to modeling concepts, providing starting code for a variety of exercises where students add additional code to solve the problem and provide an analysis of the outcomes. In this way, the book builds both modeling and programming expertise with a "just-in-time" approach so that by the end of the book, students can take on relatively simple modeling example on their own. Each chapter is supplemented with references to additional reading, tutorials, and exercises that guide students to additional help and allows them to practice both their programming and analytical modeling skills. In addition, each of the programming related chapters is divided into two parts - one for MATLAB and one for Python. In these chapters, the authors also refer to additional online tutorials that students can use if they are having difficulty with any of the topics. The book culminates with a set of final project exercise suggestions that incorporate both the modeling and programming skills provided in the rest of the volume. Those projects could be undertaken by individuals or small groups of students. The companion website at http://www.intromodeling.com provides updates to instructions when there are substantial changes in software versions, as well as electronic copies of exercises and the related code. The website also offers a space where people can suggest additional projects they are willing to share as well as comments on the existing projects and exercises throughout the book. Solutions and lecture notes will also be available for qualifying instructors.

This second edition of Foundations of Python Network Programming targets Python 2.5 through Python 2.7, the most popular production versions of the language. Python has made great strides since Apress released the first edition of this book back in the days of Python 2.3. The advances required new chapters to be written from the ground up, and others to be extensively revised. You will learn fundamentals like IP, TCP, DNS and SSL by using working Python programs; you will also be able to familiarize yourself with infrastructure components like memcached and message queues. You can also delve into network server designs, and compare threaded approaches with asynchronous event-based solutions. But the biggest change is this edition's expanded treatment of the web. The HTTP protocol is covered in extensive detail, with each feature accompanied by sample Python code. You can use your HTTP protocol expertise by studying an entire chapter on screen scraping and you can then test lxml and BeautifulSoup against a real-world web site. The chapter on web application programming now covers both the WSGI standard for component interoperability, as well as modern web frameworks like Django. Finally, all of the old favorites from the first edition are back: E-mail protocols like SMTP, POP, and IMAP get full treatment, as does XML-RPC. You can still learn how to code Python network programs using the Telnet and FTP protocols, but you are likely to appreciate the power of more modern alternatives like the paramiko SSH2 library. If you are a Python programmer who needs to learn the network, this is the book that you want by your side.

It's been known for years that usability testing can dramatically improve products. But with a typical price tag of $5,000 to $10,000 for a usability consultant to conduct each round of tests, it rarely happens.
In this how-to companion to "Don't Make Me Think: A Common Sense Approach to Web Usability," Steve Krug spells out a streamlined approach to usability testing that anyone can easily apply to their own Web site, application, or other product. (As he said in "Don't Make Me Think," "It's not rocket surgery.")
Using practical advice, plenty of illustrations, and his trademark humor, Steve explains how to:
Test any design, from a sketch on a napkin to a fully-functioning Web site or applicationKeep your focus on finding the most important problems (because no one has the time or resources to fix them all)Fix the problems that you find, using his "The least you can do" approachBy paring the process of testing and fixing products down to its essentials ("A morning a month, that's all we ask"), "Rocket Surgery" makes it realistic for teams to test early and often, catching problems while it's still easy to fix them. "Rocket Surgery Made Easy" adds demonstration videos to the proven mix of clear writing, before-and-after examples, witty illustrations, and practical advice that made "Don't Make Me Think" so popular.
