Core Servlets and Java Server Pages

Ebooks and tutorial Core Servlets and Java Server Pages (JSP) is divided into three parts: Servlets, JavaServer Pages, and Supporting Technologies.

Part I: Servlets
Part I covers servlet development with the 2.1 and 2.2 specifications.
Although version 2.2 (along with JSP 1.1) is mandated by the Java 2 Platform, Enterprise Edition (J2EE), many commercial products are still at the earlier releases, so it is important to understand the differences.
Also, although servlet code is portable across a huge variety of servers and operating systems, server setup and configuration details are not standardized.
So, I include specific details for Apache Tomcat, Sun’s JavaServer Web Development Kit (JSWDK), and the Java Web Server.

Servlet topics include:
• When and why you would use servlets
• Obtaining and configuring the servlet and JSP software
• The basic structure of servlets
• The process of compiling, installing, and invoking servlets
• Generating HTML from servlets
• The servlet life cycle
• Page modification dates and browser caches
• Servlet debugging strategies
• Reading form data from servlets
• Handling both GET and POST requests with a single servlet
• An on-line resume posting service
• Reading HTTP request headers from servlets
• The purpose of each of the HTTP 1.1 request headers
• Reducing download times by compressing pages
• Restricting access with password-protected servlets
• The servlet equivalent of each standard CGI variable
• Using HTTP status codes
• The meaning of each of the HTTP 1.1 status code values
• A search engine front end
• Setting response headers from servlets
• The purpose of each of the HTTP 1.1 response headers
• Common MIME types
• A servlet that uses the Refresh header to repeatedly access ongoing computations
• Servlets that exploit persistent (keep-alive) HTTP connections
• Generating GIF images from servlets
• Cookie purposes and problems
• The Cookie API
• Some utilities that simplify cookie handling
• A customized search engine front end
• The purposes of session tracking
• The servlet session tracking API
• Using sessions to show per-client access counts
• An on-line store that uses session tracking, shopping carts, and pages automatically built from catalog entries

Part II: JavaServer Pages
JSP provides a convenient alternative to servlets for pages that mostly consist of fixed content.
Part II covers the use of JavaServer Pages version 1.0 and 1.1.
JSP topics include:
• When and why you would use JavaServer Pages
• How JSP pages are invoked
• Using JSP expressions, scriptlets, and declarations
• Predefined variables that can be used within expressions and scriptlets
• The page directive
• Designating which classes are imported
• Specifying the MIME type of the page
• Generating Excel spreadsheets
• Controlling threading behavior
• Participating in sessions
• Setting the size and behavior of the output buffer
• Designating pages to process JSP errors
• XML-compatible syntax for directives
• Including JSP files at the time the main page is translated into a servlet
• Including HTML or plain text files at the time the client requests the page
• Including applets that use the Java Plug-In
• Using JavaBeans with JSP
• Creating and accessing beans
• Setting bean properties explicitly
• Associating bean properties with input parameters
• Automatic conversion of bean property types
• Sharing beans among multiple JSP pages and servlets
• Creating JSP tag libraries
• Tag handler classes
• Tag library descriptor files
• The JSP taglib directive
• Simple tags
• Tags that use attributes
• Tags that use the body content between their start and end tags
• Tags that modify their body content
• Looping tags
• Nested tags
• Integrating servlets and JSP
• Forwarding requests from servlets to static and dynamic resources
• Using servlets to set up beans for use by JSP pages
• An on-line travel agency combining servlets and JSP
• Including JSP output in servlets
• Forwarding requests from JSP pages

Part III: Supporting Technologies
Part III covers three topics that are commonly used in conjunction with servlets and JSP: HTML forms, applets talking to servlets, and JDBC.
Topics include:
• Sending data from forms
• Text controls
• Push buttons
• Check boxes and radio buttons
• Combo boxes and list boxes
• File upload controls
• Server-side image maps
• Hidden fields
• Grouping controls
• Tab ordering
• A Web server for debugging forms
• Sending GET data from an applet and having the browser display the results
• Having applets send GET data and process the results themselves (HTTP tunneling)
• Using object serialization to exchange high-level data structures between applets and servlets
• Having applets send POST data and process the results themselves
• Applets bypassing the HTTP server altogether
