Accelerating JSP Tag Development with Jakarta Velocity

by Gregory Gerard 05/01/2002 Writing JSP tags can be tedious, even under the best of circumstances. Often, I merely wish to push out lightly-parameterized HTML to, for instance, control the layout of an intricate (but often used) table format. While you might assert that this is precisely the purpose of Java Server Pages, with its directive for including JSPs through the or <%@include ...%> elements, it can often be overkill and cumbersome to maintain. With a simple...

Easy Development with the JSP Standard Tag Library (JSTL)

By Olexiy Prokhorenko Go to page: 1 2 Next In this article, I will introduce you to interesting and flexible technology based on JSP, called JSTL . JSTL stands for Java Server Pages Standard Tag Library. Although JSP has already become very popular, it is not widely used in the development of easy, rapidly-done front-ends with SQL databases. Once you get to know JSTL , you will understand its advantages and will see numerous ways how it can be used in your everyday programmer's life. I...

JSP Standard Tag Libraries, Part 1

03/13/2002 Many of us have been working with the Java Server Pages technology for quite some time and have become familiar with custom tags. Custom tags have made working with JSPs not only easier, but also more efficient. If a custom tag has been created, tested, and debugged, then it only is logical that, as a developer, you want to grab the golden ring of OOD: reusable components. Working with custom tags is one avenue to explore in the world of reuse. But wouldn't it be better, more...

JSP Standard Tag Libraries, Part 2

05/08/2002 This article is the second in a series on JSTL, the JSP Standard Tag Library. If you need a primer as to what JSTL encompasses, check out part one of this series.

We'll go though samples using the conditionals, iteration, and URL, U18N, SQL, and XML tags. The goal of this article is to show the key components of the JSTL, learn how to use the...

An Introduction to JSP Standard Template Library (JSTL)

By Jeff Heaton Introduction 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. You may be wondering why we need yet another HTML generation programming language. JSTL was introduced was to allow JSP programmers to program using tags...

Servlets and JSP Pages Best Practices

by Qusay H. Mahmoud March 2003 Java Servlet technology and JavaServer Pages (JSP pages) are server-side technologies that have dominated the server-side Java technology market; they've become the standard way to develop commercial web applications. Java developers love these technologies for myriad reasons, including: the technologies are fairly easy to learn, and they bring the Write Once, Run Anywhere paradigm to web applications. More importantly, if used effectively by following...

Building Java Server Pages

by Mark Webber If you've ever used Microsoft's very popular Active Server Pages (ASP) then you'll have a good idea of what JSP is. It consists of HTML or XML markup into which special tags and code blocks are inserted. The code is executed on the server and the result is a dynamic page that is returned to the client browser. Although JSPs are simple to build they have at their disposal the full power of object-oriented Java and the Java Server API. JSPs make heavy use of Java Beans,...

Enrich Your Applications with JSP Components

By Michael Klaene Go to page: 1 2 Next JavaServer Pages, commonly referred to as JSP, has been a core technology in the J2EE world for years. Prior to the introduction of JSP, Java developers built dynamic Web pages by writing Java Servlets that spooled out HTML code. With the arrival of JSP, the focus of Web page development returned to HTML markup, which could be enhanced with small scriptlets of Java to take care of the dynamic portions of the page. A subsequent release of the JSP...

JSTL 1.0: Standardizing JSP, Part 1

by Hans Bergsten , author of JavaServer Pages, 2nd Edition 08/14/2002 June 11, 2002 started a new phase for JSP developers. That's when the JSP Standard Tag Library (JSTL) 1.0 specification was released. The Apache Taglibs project followed up with a reference implementation a few days later. JSTL answers developers' demand for a set of standardized JSP custom actions to handle the tasks needed in almost all JSP pages, including conditional processing, internationalization, database...

A Custom JSP Tag Library for Dynamic Menus

by Prabu Arumugam 04/09/2003 Menus are critical components of software applications. Implementing a static menu is relatively easy--just categorize and customize the application's functionality once. Implementing a dynamic menu, unique for each user depending on his or her profile and preferences, is both challenging and cumbersome. While the Java programming language has built-in support to create basic menu structures, JSP lacks support. Web applications must use either Java applets...

JSP: Creating Dynamic Titles

By Stephanie Kaminaris and Jose Annunziato One of the main advantages of JavaServer Pages is the ability to generate dynamic content. JSPs generate dynamic HTML pages by using Java control structures like for loops and if statements. As a result, forms can be generated dynamically following some specified logical layout. Consider the simple task of generating a string repeatedly. This can easily be done by putting the string inside a for loop. The listing below provides a simple example...

XSLT and JSP: A Dynamic Combination

S ince Sun released the Java 2 Enterprise Edition (J2EE) specification in December of 1999, there has been a tremendous push toward object-oriented programming. The Enterprise JavaBeans component is built around business objects session beans representing different parts of a business model and entity beans representing persistent data in a database. When creating dynamic content, you can reuse these objects by employing tags and custom tags within JavaServer Pages (JSP). Further, these...

Verifying User Input Using JSP Tag Libraries

By Vlad Kofman Go to page: 1 2 Next In any Web-based application where program logic requires information submitted by the user to be validated, the creators of the application can check data in two ways. The first method is to do validation on the client side, even before anything is submitted to the server. Usually, this is done using JavaScript running in the client's Internet browser. While the form is being submitted, the script will check all required fields and pop up error...
