* [[JavaServerJakarta Server Faces|Jakarta Faces]] (JSF), [[Apache Tapestry]] and [[Apache Wicket]] are competing component-based technologies, abstracting the [[Stateless protocol|stateless]] HTTP request-response cycle and the [[JavaJakarta Servlet]] [[API]] behind an [[Object-oriented programming|object-oriented]], event-driven component model.

* In contrast, Struts and the [[Spring Framework|Spring MVC Framework]] are action-oriented frameworks that provide a thinner [[abstraction layer]] over the servlet [[API]].

* Apache Tiles is a templating framework designed to work with Struts.

* [[Facelets]] is a view definition and templating technology designed to work with JSF.

* [[SiteMesh]] can be used with any [[JavaServerJakarta Server Pages|JSPJakarta Pages]] (JSP).

* Facelets, Tapestry and Wicket have their own templating approaches based on [[HTML]]/[[XHTML]].

* [[Apache Click]] uses HTML based [[Apache Velocity]] templates and [[Plainplain Oldold Java Objectobject]]s (POJOs), with [[JavaServer Pages]]JSP optional.

==Servlet API==

{{main | JavaJakarta Servlet API}}

The Servlet API is the foundation of almost all Java Web View technologies. Servlet provides the basic mechanism for writing Java [[Classclass (computer programming)|classesclass]]es for web applications. Servlets can respond to HTTP requests, create cookies and maintain sessions.

==JavaServerJakarta Pages (JSP) ==

{{main |Jakarta JavaServerServer Pages}}

* Built on top of the Servlet API, JSP provides a document-centric, tag-based templates, server programming model which can generate many forms of textual content.

Line 37:

==Apache Struts==

{{main | Apache Struts 2}}

* Struts provides for a [[Couplingcoupling (computer programming)|decoupling]] of the Controller and the View.

* Requests are received by a Java Class (Controller) which can decide which View to display.

* The actual View can be written in different view technologies, like JSP, free marker template, velocity template etc.

Line 46:

==Apache Tapestry==

{{main | Apache Tapestry}}

* A component-based view framework.

Line 56:

* Uses the [[Post/Redirect/Get]] navigation pattern for form submission.

* '''Competitor''': Wicket, JSF, HybridJava

==Apache Tiles==

{{see also |d:Special:EntityPage/Q28912908|l1=Apache Tiles}}

* This is an HTML templating framework based on the [[composite pattern]].

* It allows for the HTML page to be broken up into multiple "pagelets", called Templates, Definitions and Composing pages.

* At [[runtime (program lifecycle phase)|runtime]] the pagelets are stitched together to generate the final HTML. Pages are written in JSP.

* '''Competitor''': SiteMesh

==Apache Wicket==

{{main | Apache Wicket}}

* A component-based view framework.

Line 68 ⟶ 76:

* '''Competitor''': Tapestry, JSF, HybridJava

==JavaServerJakarta Faces (JSF) and Facelets==

{{main |Jakarta JavaServerServer Faces | Facelets}}

* A specification for component-based view frameworks.

* [[Eclipse Mojarra]] and Apache MyFaces implementations are available

* Typically uses Facelets for XML/XHTML-based templating.

* Classes are written as POJOs, with Annotations or XML configuration files used to associate them with page and component templates.

Line 82 ⟶ 90:

==SiteMesh==

{{main | SiteMesh}}

* SiteMesh is an HTML templating framework based on the "Decoration" model.

Line 92 ⟶ 100:

==Spark==

{{main | Spark (software)}}

* Spark a micro web framework built around a simple routing system

Line 98 ⟶ 106:

* It supports three different templates engines: [[Apache Velocity|Velocity]], [[FreeMarker]] and [[Mustache (template system)|Mustache]]

* It aims to facilitate rapid development, and does not make use of annotations or proprietary solutions.
