• The Problems with JSP.
• Note: In the time since this essay was written, JSP has gone through two updates and can now be considered better (although yet more complicated) than it was when this article was written. ... For an in-depth discussion of JSP and its competitors, see the 2nd Edition of my book Java Servlet Programming. ...
• By now almost everyone using servlets has heard about JavaServer Pages (JSP), a Sun-invented technology built on top of servlets. Sun has done a marvelous job promoting JSP as a way to get HTML out of servlet code, speeding web application development and improving web page maintenance. In fact, the official "Application Programming Model" document published by Sun has gone so far as to say, "JSP technology should be viewed as the norm while the use of servlets will most likely be the exception. ... 9, December 15, 1999, Draft Release) This paper evaluates whether that claim is valid -- by comparing JSP to another technology built on servlets: template engines. ...
• Along Comes JSP.
• Around this time JSP 0. ... There was no attempt to hide the Servlet API; JSP was considered a "cheap" way for a Java programmer to write a servlet. ...
• So people matured in their use of JSP and started to rely more on JavaBeans. Beans were written to contain business logic code needed by the JSP page. Much of the code inside the JSP page could be moved out of the page into the bean with only minimal hooks left behind where the page would access the bean. ...
• More recently, people have started to note that JSP pages used this way are really a "view". ... Why must a client directly submit its request to a view? Shouldn't the client make a request to some general server component and let the server determine the JSP view to return? .
• This belief caused many people to adopt what has been called the "Model 2" design, named after an architecture laid out in the JSP 0. ... This data is then passed internally to a JSP page "view" for rendering, where it appears to the JSP page like a normal embedded JavaBean. The appropriate JSP page can be selected to do the display, depending on the logic inside the controlling servlet. The JSP page becomes a nice template view. ...

• Reactions to "The Problems with JSP".
• Reader reaction to the article posted here two weeks ago titled, "The Problems with JSP" has been tremendous, generating around 100 messages on the public mailing lists (jsp-interest, servlet-interest, and the official webmacro list) and nearly another 100 more to me individually. ...
• Martin Jarvis: "How great it is to find someone else sharing my doubts about JSP. ...
• Robert Fisher: "I completely agree with the article "The Problems with JSP". For a while now, I've been trying to explain to everyone I know why JSP isn't the answer to separating code from content, but I haven't been able to articulate it as well as the article did. ...
• I love JSP. ... But, if separating code and content is your goal, JSP isn't the answer. ... Anthony Nemmer: "Why not just get rid of all that JSP servlet crap and use perl ? =)" Boy, I hope it was a joke. ...
• While the majority of people were supportive, the majority of words (especially on the JSP mailing list) have been defending JSP. Josh Hunt "I just got done reading your article on the problems with JSP. I am working on a project that makes heavy use of JSP. ...
• Scott Stirling "I got the point of the non-JSP alternatives being available and perhaps overlooked. I also got the one that JSP shouldn't be seen as the logical replacement for servlets. ...
• Kevin Duffey "Well, I dont much agree with your article, at least in the way of a template engine being a better alternative to JSP. I can see how in some cases it may make sense for those either too lazy or too unwiling to understand the JSP syntax. To me, a template engines syntax means learning a lot more than JSP syntax. Sure, you can mistype the <%! with <%, but if you learn JSP, you'll know when to use one or the other. " Most of the responses have been highly focused on whether JSP or WebMacro is superior technology. This debate misses the main question: Is it valid for the official "Application Programming Model" document published by Sun and a public record of Sun's philosophy to say, "JSP technology should be viewed as the norm while the use of servlets will most likely be the exception. ...

• Early Adopter JSP Standard Tag Library by Jayson Falkner (Author), James Hart, Richard Huss, Cindy Nordahl .
• 1 person recommended JSTL in Action instead of Early Adopter JSP Standard Tag Library.
• JavaServer Pages, or JSP, is a Java Enterprise technology which enables web programmers to build pages using special tags which access Java code running on the server. As of JSP 1. 1, there has also been the capability to specify custom JSP tag libraries, or taglibs, and many such libraries have been developed to enable developers to integrate different technologies into their JSP applications. The JSP Standard Tag Library, JSTL, is set to standardize the common features of many such libraries into a core set of tags of use to every JSP developer. ...
• A core element of the library is its support for expression languages, which are used to share and access data between JSP pages. ...
• This book has been developed at the same time as the first release of the JSP standard tag library, and presents a practical overview of what the new tag library allows JSP developers to do. ...
• For someone who makes good living by having superior JSP skills, this book may in some sentence somewhere provide some little angle or insight which makes it worth the time spent reading it. ...
• This book is excellent for complete understand of the JSP Standard Library. If you're JSP Developer this book will be in your personal library. ...

• JSP Security.
• Brief Overview of JSP .
• The pages are preprocessed and converted to Java servlets by the JSP engine. ... Although they are functionally equivalent, JSP represents a reversed approach to dynamic content generation as compared to Java servlets in that the focus is on documents with embedded Java code instead of applications with embedded HTML. JSP provides additional HTML-like tags to interact with JavaBeans components for external functionality and access to reusable objects. A noteworthy characteristic of the JSP syntax is that although the HTML syntax is a subset of it (a pure HTML page is a valid JSP page), the reverse is not necessarily true. In particular, JSP allows the embedding of tags within other tags as to facilitate dynamic generation of format as well as content. The following example is a valid JSP construct: .
• In comparison to the CGI protocol, JSP offers improved performance and session management (persistent states). ...
• By the sheer virtue of providing access to resources on a server, insecure Java servlets derived from JSP pages can put at risk any or all of the server, the network on which this server resides, the clients accessing the pages, and through possible DDoS and worm distribution attacks, the entire Internet. ... Furthermore, JSP is a fairly complex architecture, in which many components come together. ... And on top of that, although all existing JSP implementations are built around Java, the JSP specification allows virtually any other language to play this role. ...
• In short, there are plenty of opportunities for introducing vulnerabilities in a JSP system. ...
• Some source of user input for a JSP server include, but are not limited to: .
• Naturally, JSP can make calls to native code stored in libraries (through JNI) and execute external commands. ...
• The following JSP construct accessing the JDBC API is highly insecure, since an attacker can embed command separation characters in the submitted input and thus execute unwanted commands on the SQL server: .

• An Introduction to JSP Standard Template Library (JSTL).
• The JSP Standard Template Library (JSTL) is a very new component released by Sun for JSP programming. JSTL allows you to program your JSP pages using tags, rather than the scriptlet code that most JSP programmers are already accustomed to. JSTL can do nearly everything that regular JSP scriptlet code can do. ...
• JSTL was introduced was to allow JSP programmers to program using tags rather than Java code. ... We will examine a very simple JSP page that counts to ten. We will examine this page both as regular scriptlet-based JSP, and then as JSTL. When the count to ten example is programmed using scriptlet based JSP, the JSP page appears as follows.
• <html> <head> <title>Count to 10 in JSP scriptlet</title> </head> <body> <% for(int i=1;i<=10;i++) {%> <%=i%><br/> <% } %> </body> </html> .
• The readability of JSP scriptlet code does not just apply to human beings. ... Currently, most HTML authoring tools will segregate JSP scriptlet code as non-editable blocks. The HTML authoring tools usually do not modify the JSP scriptlet code directly.
• When you examine the preceding source code, you can see that the JSP page consists entirely of tags. ...
• To use JSTL, you must have a JSP 1. ... One of the most commonly used JSP containers is the Apache Tomcat Web server. ... Using Tomcat alone will allow you to use regular JSP scriptlet code. ... com/products/jsp/jstl/. ...

But the method signatures are different for both Servlet and JSP. Servlet has init(), service() and destroy() methods where as JSP has jspInit(), _jspService() and jspDestroy() methods. JSP has some advantages over servlet. JSP gives good separation between presentation (html) and business logic. ... Here I use JSP's Servlet instead of Servlet to differentiate between both.

• Generally a JSP generates not only dynamic data but also static data. Programmers often make a mistake by creating both dynamic and static data from JSP page. Obviously there is a reason to create dynamic data because of its nature but there is no need to create static data every time for every request in JSP page.
