Summary

Rather than focus on theory and concept, this new addition to our Cookbook line presents scores of real- world problems, and provides concise, practical solutions to each. With literally hundreds of examples and thousands of lines of code, any Java web developer who uses JavaServer Pages or servlets, even casually, will find useful tips and techniques in this book, as well as full-fledged solutions to significant web application development problems. The Java Servlet & JSP Cookbook lets developers put theory from other API-focused books into practice.
