Book Description

The Apache ActiveMQ message broker is an open source implementation of the Java Message Service spec. It makes for a reliable hub in any message-oriented enterprise application and integrates beautifully with Java EE containers, ESBs, and other JMS providers.

ActiveMQ in Action is all you’ll need to master ActiveMQ. It starts from the anatomy of a JMS message and moves quickly through connectors, message persistence, authentication, and authorization. By following a running example (a stock portfolio app), you’ll pick up the best practices distilled by the authors from their long and deep involvement with this technology.

What’s Inside

• How to design message-based apps
• How to implement EI patterns using Camel
• How to administer ActiveMQ
• How to integrate with Geronimo, JBoss, Spring, and more

This book requires a working knowledge of Java, but no previous experience with ActiveMQ or other message brokers is needed.

Book Description

Want your web site to display more quickly? This book presents 14 specific rules that will cut 25% to 50% off response time when users request a page. Author Steve Souders, in his job as Chief Performance Yahoo!, collected these best practices while optimizing some of the most-visited pages on the Web. Even sites that had already been highly optimized, such as Yahoo! Search and the Yahoo! Front Page, were able to benefit from these surprisingly simple performance guidelines.

The rules in High Performance Web Sites explain how you can optimize the performance of the Ajax, CSS, JavaScript, Flash, and images that you’ve already built into your site — adjustments that are critical for any rich web application. Other sources of information pay a lot of attention to tuning web servers, databases, and hardware, but the bulk of display time is taken up on the browser side and by the communication between server and browser. High Performance Web Sites covers every aspect of that process.

Each performance rule is supported by specific examples, and code snippets are available on the book’s companion web site. The rules include how to:

• Make Fewer HTTP Requests
• Use a Content Delivery Network
• Add an Expires Header
• Gzip Components Download Now »
