Looking to study up for the new J2EE 1.5 Sun Certified Web Component Developer (SCWCD) exam?

This book will get you way up to speed on the technology you'll know it so well, in fact, that you can pass the brand new J2EE 1.5 exam. If that's what you want to do, that is. Maybe you don't care about the exam, but need to use servlets and JSPs in your next project. You're working on a deadline. You're over the legal limit for caffeine. You can't waste your time with a book that makes sense only AFTER you're an expert (or worse, one that puts you to sleep).

Learn how to write servlets and JSPs, what makes a web container tick (and what ticks it off), how to use JSP's Expression Language (EL for short), and how to write deployment descriptors for your web applications. Master the c:out tag, and get a handle on exactly what's changed since the older J2EE 1.4 exam. You don't just pass the new J2EE 1.5 SCWCD exam, you'll understand this stuff and put it to work immediately.

Head First Servlets and JSP doesn't just give you a bunch of facts to memorize; it drives knowledge straight into your brain. You'll interact with servlets and JSPs in ways that help you learn quickly and deeply. And when you're through with the book, you can take a brand-new mock exam, created specifically to simulate the real test-taking experience.

  • 1. Intro and Overview: Why use Servlets & JSPs?
    • Everybody wants a web site
    • What does your web server do?
    • What does a web client do?
    • Clients and servers know HTML and HTTP
    • Two-minute HTML guide
    • What you write... (the HTML)
    • What the browser creates...
    • What is the HTTP protocol?
    • HTML is part of the HTTP response
    • If thats the response, whats in the request?
    • GET is a simple request, POST can send user data
    • Its true... you can send a little data with HTTP GET
    • Anatomy of an HTTP GET request
    • Anatomy of an HTTP POST request
    • Anatomy of an HTTP response, and what the heck is a MIME type?
    • All the pieces. On one page.
    • URL. Whatever you do, dont pronounce it Earl.
    • Directory structure for a simple Apache web site
    • Web servers love serving static web pages
    • But sometimes you need more than just the web server
    • Two things the web server alone wont do
    • The non-Java term for a web server helper app is CGI program
      • Servlets and CGI both play the role of a helper app in the web server
    • Servlets Demystified (write, deploy, run)
      • Actually, trying to format HTML inside a servlets out.println() pretty much sucks.
    • JSP is what happened when somebody introduced Java to HTML
  • 2. High-Level Overview: Web App Architecture
    • What is a Container?
    • What if you had Java, but no servlets or Containers?
    • What does the Container give you?
    • How the Container handles a request
    • How it looks in code (what makes a servlet a servlet)
    • Youre wondering how the Container found the Servlet...
    • A servlet can have THREE names
    • Using the Deployment Descriptor to map URLs to servlets
    • But wait! Theres more you can do with the DD
    • Story: Bob Builds a Matchmaking Site
    • He starts to build a bunch of servlets... one for each page
    • But then it gets ugly, so he adds JSPs
    • But then his friend says, You ARE using MVC, right?
    • The Model-View-Controller (MVC) Design Pattern fixes this
    • Applying the MVC pattern to the matchmaking web app
    • But then his friend Kim takes a look
    • Is there an answer?
    • A working Deployment Descriptor (DD)
    • How J2EE fits into all this
  • 3. Hands-on MVC: Mini MVC Tutorial
    • Lets build a real (small) web application
    • The Users View of the web applicationa Beer Advisor
    • Heres the architecture...
    • Creating your development environment
    • Creating the deployment environment
    • Our roadmap for building the app
    • The HTML for the initial form page
    • Deploying and testing the opening page
    • Mapping the logical name to a servlet class file
    • The first version of the controller servlet
    • Compiling, deploying, and testing the controller servlet
    • Building and testing the model class
    • Enhancing the servlet to call the model, so that we can get REAL advice...
    • Servlet version two code
    • Key steps for servlet version two
    • Review the partially completed, MVC beer advice web application
    • Create the JSP view that gives the advice
    • Enhancing the servlet to call the JSP (version three)
    • Code for servlet version three
    • Compile, deploy, and test the final app!
    • There is still so much to learn.
  • 4. Request and Response: Being a Servlet
    • Servlets are controlled by the Container
    • But theres more to a servlets life
      • Your servlet inherits the lifecycle methods
    • The Three Big Lifecycle Moments
    • Each request runs in a separate thread!
    • In the beginning: loading and initializing
      • Servlet Initialization: when an object becomes a servlet
      • But a Servlets REAL job is to handle requests. Thats when a servlets life has meaning.
      • Request and Response: the key to everything, and the arguments to service()
    • The HTTP request Method determines whether doGet() or doPost() runs
    • Actually, one or more of the other HTTP Methods might make a (brief) appearance on the exam...
    • The difference between GET and POST
    • No, its not just about the size
    • The story of the non-idempotent request
    • POST is not idempotent
    • What determines whether the browser sends a GET or POST request?
      • What happens if you do NOT say method=POST in your <form>?
    • POST is NOT the default!
    • Sending and using a single parameter
    • Sending and using TWO parameters
    • Besides parameters, what else can I get from a Request object?
    • Review: servlet lifecycle and API
    • Review: HTTP and HttpServletRequest
    • So thats the Request... now lets see the Response
    • Using the response for I/O
    • Imagine you want to send a JAR to the client...
    • Servlet code to download the JAR
    • Whoa. Whats the deal with content type?
    • Youve got two choices for output: characters or bytes
    • You can set response headers, you can add response headers
    • But sometimes you just dont want to deal with the response yourself...
    • Servlet redirect makes the browser do the work
      • Using relative URLs in sendRedirect()
    • A request dispatch does the work on the server side
    • Redirect vs. Request Dispatch
    • Review: HttpServletResponse
    • Coffee Cram: Mock Exam Chapter 4
    • Coffee Cram: Chapter 4 Answers
  • 5. Attributes and Listeners: Being a Web App
    • Kim wants to configure his email address in the DD, not hard-code it inside the servlet class
    • Init Parameters to the rescue
    • You cant use servlet init parameters until the servlet is initialized
    • The servlet init parameters are read only ONCEwhen the Container initializes the servlet
    • Testing your ServletConfig
    • How can a JSP get servlet init parameters?
      • What about the way we did it with the beer app? We passed the model info to the JSP using a request attribute...
    • Setting a request attribute works... but only for the JSP to which you forwarded the request
    • Context init parameters to the rescue
    • Remember the difference between servlet init parameters and context init parameters
    • ServletConfig is one per servlet ServletContext is one per web app
    • So what else can you do with your ServletContext?
    • What if you want an app init parameter thats a database DataSource?
      • What she really wants is a listener.
      • She wants a ServletContextListener
      • Tutorial: a simple ServletContextListener
      • Making and using a context listener
      • We need three classes and one DD
      • Writing the listener class
      • Writing the attribute class (Dog)
      • Writing the servlet class
      • Writing the Deployment Descriptor
      • Compile and deploy
      • Try it out
      • Troubleshooting
      • The full story...
      • Listeners: not just for context events...
      • The eight listeners
      • The HttpSessionBindingListener
    • What, exactly, is an attribute?
      • Attributes are not parameters!
      • The Three Scopes: Context, Request, and Session
      • Attribute API
      • The dark side of attributes...
      • But then something goes horribly wrong...
      • Context scope isnt thread-safe!
      • The problem in slow motion...
      • How do we make context attributes thread-safe?
      • Synchronizing the service method is a spectacularly BAD idea
      • Synchronizing the service method wont protect a context attribute!
      • You dont need a lock on the servlet... you need the lock on the context!
      • Are Session attributes thread-safe?
      • Whats REALLY true about attributes and thread-safety?
      • Protect session attributes by synchronizing on the HttpSession
      • SingleThreadModel is designed to protect instance variables
      • But how does the web container guarantee a servlet gets only one request at a time?
      • Which is the better STM implementation?
      • Only Request attributes and local variables are thread-safe!
      • Request attributes and Request dispatching
      • RequestDispatcher revealed
      • Whats wrong with this code?
      • Youll get a big, fat IllegalStateException!
    • Coffee Cram: Mock Exam Chapter 5
    • Coffee Cram: Chapter 5 Answers
  • 6. Session Management: Conversational state
    • Kim wants to keep client-specific state across multiple requests
    • Its supposed to work like a REAL conversation...
    • How can he track the clients answers?
    • How sessions work
    • One problem... how does the Container know who the client is?
    • The client needs a unique session ID
    • How do the Client and Container exchange Session ID info?
      • Cookies
    • The best part: the Container does virtually all the cookie work!
    • What if I want to know whether the session already existed or was just created?
    • What if I want ONLY a pre-existing session?
    • You can do sessions even if the client doesnt accept cookies, but you have to do a little more work...
      • URL rewriting: something to fall back on
      • URL rewriting kicks in ONLY if cookies fail, and ONLY if you tell the response to encode the URL
      • URL rewriting works with sendRedirect()
      • Getting rid of sessions
      • How we want it to work...
      • The HttpSession interface
      • Key HttpSession methods
      • Setting session timeout
      • Can I use cookies for other things, or are they only for sessions?
      • Using Cookies with the Servlet API
      • Simple custom cookie example
      • Custom cookie example continued...
      • Key milestones for an HttpSession
      • Session lifecycle Events
    • Dont forget about HttpSessionBindingListener
      • Session migration
      • The Beer Web App distributed across two VMs
      • Session migration in action
    • HttpSessionActivationListener lets attributes prepare for the big move...
      • Listener examples
      • Listener examples
      • Listener examples
      • Session-related Listeners
      • Session-related Event Listeners and Event Objects API overview
    • Session-related Listeners
    • Coffee Cram: Mock Exam Chapter 6
    • Coffee Cram: Chapter 6 Answers
  • 7. Using JSP: Being a JSP
    • In the end, a JSP is just a servlet
    • Making a JSP that displays how many times its been accessed
    • She deploys and tests it
    • The JSP doesnt recognize the Counter class
    • Use the page directive to import packages
    • But then Kim mentions expressions
    • Expressions become the argument to an out.print()
    • Kim drops the final bombshell...
    • Declaring a variable in a scriptlet
    • What REALLY happens to your JSP code?
    • We need another JSP element...
    • JSP Declarations
    • Time to see the REAL generated servlet
    • The out variable isnt the only implicit object...
    • A comment...
    • API for the generated servlet
    • Lifecycle of a JSP
    • Translation and compilation happens only ONCE
    • Initializing your JSP
      • Configuring servlet init parameters
      • Overriding jspInit()
    • Attributes in a JSP
    • Using PageContext for attributes
    • Examples using pageContext to get and set attributes
    • While were on the subject... lets talk more about the three directives
      • Attributes to the page directive
    • Scriptlets considered harmful?
    • There didnt used to BE an alternative.
    • EL: the answer to, well, everything.
    • Sneak peek at EL
    • Using <scripting-invalid>
    • You can choose to ignore EL
      • El is enabled by default!
    • But wait... theres still another JSP element we havent seen: actions
    • Coffee Cram: Mock Exam Chapter 7
    • Coffee Cram: Chapter 7 Answers
  • 8. Scriptless JSP: Script-free pages
    • Our MVC app depends on attributes
    • But what if the attribute is not a String, but an instance of Person?
    • We need more code to get the Persons name
    • Person is a JavaBean, so well use the bean-related standard actions
    • Deconstructing <jsp:useBean> and <jsp:getProperty>
      • Declare and initialize a bean attribute with <jsp:useBean>
      • Get a bean attributes property value with <jsp:getProperty>
    • <jsp:useBean> can also CREATE a bean!
    • You can use <jsp:setProperty>
    • <jsp:useBean> can have a body!
    • Generated servlet when <jsp:useBean> has a body
    • Can you make polymorphic bean references?
    • Adding a type attribute to <jsp:useBean>
    • Using type without class
    • The scope attribute defaults to page
    • Going straight from the request to the JSP without going through a servlet...
    • The param attribute to the rescue
    • But wait ! It gets even better...
    • If you can stand it, it gets even BETTER...
    • Bean tags convert primitive properties automatically
    • But what if the property is something OTHER than a String or primitive?
    • Trying to display the property of the property
    • Expression Language (EL) saves the day!
    • Deconstructing the JSP Expression Language (EL)
    • Using the dot (.) operator to access properties and map values
    • The [] operator is like the dot only way better
    • The [] gives you more options...
    • Using the [] operator with an array
    • A String index is coerced to an int for arrays and Lists
    • For beans and Maps you can use either operator
    • If its NOT a String literal, its evaluated
    • You can use nested expressions inside the brackets
    • You cant do ${foo.1}
    • EL renders raw text, including HTML
      • The same is true for JSP expression tags...
      • ... and for the jsp:getProperty standard action
    • The EL implicit objects
    • Request parameters in EL
    • What if you want more information from the request?
    • The requestScope is NOT the request object
    • Scope implicit objects can save you
    • Getting Cookies and init params
      • She doesnt know about EL functions
    • Imagine you want your JSP to roll dice
    • Deploying an app with static functions
    • And a few other EL operators...
    • EL handles null values gracefully
    • JSP Expression Language (EL) review
    • Reusable template pieces
    • The include directive
    • The <jsp:include> standard action
    • Theyre NOT the same underneath...
    • The include directive happens at translation time <jsp:include> happens at runtime
    • The include directive at first request
    • The <jsp:include> standard action at first request
    • Uh-oh. Shes right...
    • The way we SHOULD have done it
    • Customizing the included content with <jsp:param>
    • The <jsp:forward> standard action
    • A conditional forward...
    • How it runs...
    • With <jsp:forward>, the buffer is cleared BEFORE the forward
      • She doesnt know about JSTL tags
    • Bean-related standard action review
    • The include review
    • Coffee Cram: Mock Exam Chapter 8
    • Coffee Cram: Chapter 8 Answers
  • 9. Using JSTL: Custom tags are powerful
    • EL and standard actions are limited
    • The case of the disappearing HTML (reprised)
    • Theres a better way: use the <c:out> tag
      • You can explicitly declare the conversion of XML entities
      • You can explicitly declare NO conversion of XML entities
      • Conversion happens by default
    • Null values are rendered as blank text
    • Set a default value with the default attribute
      • Or you can do it this way:
    • Looping without scripting
    • <c:forEach>
    • Deconstructing <c:forEach>
    • You can even nest <c:forEach> tags
    • Doing a conditional include with <c:if>
    • But what if you need an else?
    • The <c:if> tag wont work for this
    • The <c:choose> tag and its partners <c:when> and <c:otherwise>
    • The <c:set> tag... so much cooler than <jsp:setProperty>
    • Using <c:set> with beans and Maps
    • Key points and gotchas with <c:set>
    • <c:remove> just makes sense
    • With <c:import>, there are now THREE ways to include content
    • <c:import> can reach OUTSIDE the web app
    • Customizing the thing you include
    • Doing the same thing with <c:param>
    • <c:url> for all your hyperlink needs
    • What if the URL needs encoding?
    • You do NOT want your clients to see this:
    • Make your own error pages
      • She doesnt know about the <error-page> DD tag.
    • Configuring error pages in the DD
    • Error pages get an extra object: exception
    • The <c:catch> tag. Like try/catch...sort of
    • You can make the exception an attribute
    • What if you need a tag thats NOT in JSTL?
    • Using a tag library thats NOT from the JSTL
    • Making sense of the TLD
    • Using the custom advice tag
    • The custom tag handler
    • Pay attention to <rtexprvalue>
    • <rtexprvalue> is NOT just for EL expressions
    • What can be in a tag body
    • The tag handler, the TLD, and the JSP
    • The taglib <uri> is just a name, not a location
    • The Container builds a map
    • Four places the Container looks for TLDs
    • When a JSP uses more than one tag library
    • Coffee Cram: Mock Exam Chapter 9
    • Coffee Cram: Chapter 9 Answers
  • 10. Custom Tag Development: When even JSTL is not enough...
    • Includes and imports can be messy
    • Tag Files: like include, only better
    • But how do you send it parameters?
    • To a Tag File, you dont send request parameters, you send tag attributes!
    • Arent tag attributes declared in the TLD?
    • Tag Files use the attribute directive
    • When an attribute value is really big
    • Declaring body-content for a Tag File
    • Where the Container looks for Tag Files
    • When you need more than Tag Files... Sometimes you need Java
    • Making a Simple tag handler
    • A Simple tag with a body
    • The Simple tag API
    • The life of a Simple tag handler
    • What if the tag body uses an expression?
    • A tag with dynamic row data: iterating the body
    • A Simple tag with an attribute
    • What exactly IS a JspFragment?
    • SkipPageException: stops processing the page...
    • SkipPageException shows everything up to the point of the exception
    • But what happens when the tag is invoked from an included page?
    • SkipPageException stops only the page that directly invoked the tag
    • You still have to know about Classic tag handlers
    • Tag handler API
    • A very small Classic tag handler
    • A Classic tag handler with TWO methods
    • When a tag has a body: comparing Simple vs. Classic
    • Classic tags have a different lifecycle
    • The Classic lifecycle depends on return values
    • IterationTag lets you repeat the body
    • Default return values from TagSupport
    • OK, lets get real...
    • Our dynamic <select> tag isnt complete...
    • We could just add more custom tag attributes...
    • Son of more tag attributes
    • The return of the son of more tag attributes
    • Im getting sick of these tag attributes!
    • Our tag handler code using the DynamicAttributes interface
    • The rest of the tag handler code
    • OK, there is a little bit of configuration in the TLD
    • What about Tag Files?
    • But what if you DO need access to the body contents?
    • With BodyTag, you get two new methods
    • With BodyTag, you can buffer the body
    • What if you have tags that work together?
    • A Tag can call its Parent Tag
    • Find out just how deep the nesting goes...
    • Simple tags can have Classic parents
    • You can walk up, but you cant walk down...
    • Getting info from child to parent
    • Menu and MenuItem tag handlers
    • Getting an arbitrary ancestor
    • Using the PageContext API for tag handlers

    • Enhancing the entire web application
    • How about some kind of filter?
    • Filters are modular, and configurable in the DD
    • Three ways filters are like servlets
    • Building the request tracking filter
    • A filters life cycle
    • Think of filters as being stackable
      • A conceptual call stack example
    • Declaring and ordering filters
