Although Web development tools are rapidly progressing, they still lag behind most graphical user interface GUI toolkits such as Swing or VisualWorks Smalltalk. For example, traditional GUI toolkits provide layout managers, in one form or another, that allow layout algorithms to be encapsulated and reused. This article explores a template mechanism for JavaServer Pages JSP that, like layout managers, encapsulates layout so it can be reused instead of replicated.
Because layout undergoes many changes over the course of development, it's important to encapsulate that functionality so it can be modified with minimal impact to the rest of the application. In fact, layout managers demonstrate an example of one of the tenets of object-oriented design: JSP does not provide direct support for encapsulating layout, so Webpages with identical formats usually replicate layout code; for example, Figure 1 shows a Webpage containing header, footer, sidebar, and main content sections.
In the example listed above, content is included with the JSP include directive, which allows the content of the page to vary -- by changing the included files -- without modifying the page itself. However, because layout is hard coded, layout changes require modifications to the page. If a Website has multiple pages with identical formats, which is common, even simple layout changes require modifications to all of the pages.
To minimize the impact of layout changes, we need a mechanism for including layout in addition to content; that way, both layout and content can vary without modifying files that use them. That mechanism is JSP templates. Templates are JSP files that include parameterized content. The templates discussed in this article are implemented with a set of custom tags: The template: Example 2.
Let's examine how template: For example, in the template listed in Example 2. Subsequently, template: The template is included with template: The insert start tag specifies the template to be included, in this case the template listed in Example 2.
Each put tag stores a bean in request scope and the insert end tag includes the template. The template subsequently accesses the beans as described above. A direct attribute can be specified for template: In Example 2. Websites containing multiple pages with identical formats have one template, such as the one listed in Example 2.
If the format is modified, changes are restricted to the template. Another benefit of templates and including content in general is modular design. For example, the Templates for websites in jsp file listed templates for websites in jsp Example 2. Because header. Also, although header. That is, because the template includes header.
JSP provides two ways to include content: The include directive includes the source puneri dhol mp3 full the target page at compile time and is equivalent to C's include or Java's import.
The include action includes the templates for websites in jsp response generated at runtime. Like the JSP include action, templates include content dynamically. All template content is optional, which makes a single template useful to more Webpages. For example, Figure 2. Both pages have a header, footer, and main content. The inventory page has an edit panel which the login page lacks for making inventory changes.
Web applications often discriminate content based on a user's role. For example, the same JSP template, which includes the edit panel only when the user's role is curator, produces the two pages shown in Figures 3.
The template used in Figures 3. The get tag includes content only if the user's role matches the role attribute. Let's look at how the tag handler for template: The insert templates for websites in jsp includes a template, but before it does, put tags store information -- a name, URI, and Boolean value specifying whether content should be included or printed directly -- about the content the template includes.
To ensure that each template has access only to its own information, template: Each insert start tag creates a hashtable and pushes it on the stack. The enclosed put tags create beans and store them in templates for websites in jsp newly created hashtable.
Subsequently, get tags in the included template highest resolution picture ever google the beans in the hashtable. Figure 4 shows how the stack is maintained for nested templates.
Each template in Figure 4 accesses the correct footer; footer. If the beans were stored directly in request scope, step 5 in Figure 4 would overwrite the footer bean specified in step 2.
The remainder of this article examines the implementation of the three template tags: We begin with sequence diagrams, starting with Figure 5. It illustrates the sequence of events for the insert and put tags when a template is used. If a template stack does not already exist, the insert start tag creates one and places it in request scope.
A hashtable is subsequently templates for websites in jsp and pushed on the stack. Each put start tag creates a PageParameter bean, stored in the hashtable created by templates for websites in jsp enclosing insert tag. The insert end tag includes the template. The template uses get tags templates for websites in jsp access the beans created by put tags. After the template is processed, the hashtable created by the insert start tag is popped off the stack.
Tag handler implementations for the template tags prove straightforward. Example 3. Web application components made easy with Composite View. A look at the Composite design pattern.

Optional content All template content is optional, which makes a single template useful to more Webpages. Figure 2. A login form Figure 2. An inventory page Below, you'll find the template shared by the login and inventory pages: The inventory page uses the template listed above and specifies content for the edit panel: Role-based content Web applications often discriminate content based on a user's role.

Thanks everyone in advance. Waiting for your helpful replies. BalusC k Anand Anand 12 1 8. Your question is vague and ambiguous. The term "web template" makes no sense.
Are you actually talking about CSS? If so, this is completely unrelated to JSP. But I want my JSP forms to be presented in a good way. What can I do? I'd start learning CSS.
