Usage of servlets and Jsp pages.

How to avoid Java code in Jsp files?
Designing and Developing Jsp pages.
Jsp include and jstl vs tiles, freemarker, velocity, sitemesh.
Jsp was first released by Sun Microsystems in 1999.
Jsp 2.1 leverages the Servlet 2.5 specification for its web semantics.
Note: Only the"import" page directive can
be used multiple times in the same Jsp.
Also, the tag <Jsp: doBody/> will be replaced
by the content of the child page.
Therefore, there is no way other
people can include the evil code into the Jsp file.
Jsp 2.1 supports this goal by defining annotations
for dependency injection on Jsp tag handlers and context listeners.
Supported files are added on a rolling basis and
maybe the file type Jsp is also already supported.
All the content inside the tag <Jsp: body> here will replace the <Jsp: doBody/> on your master page.
The new unified expression language is
defined in its own specification document, delivered along with the Jsp 2.1 specification.
As the technology matured, we got company-specific Java-based server-side technology from Kiva and NetDynamics,
which eventually all merged into Jsp.
As a one-shot portal for public information on government programmes, the Jsp, therefore, can advance the objective of transparency.
Plastic machine industry: plastic injection machine hinge, crosshead, moving template,
second plate sliding foot(Jsp), mold adjusting gasket, supporting template sleeve.
Performance is significantly better because Jsp allows embedding Dynamic Elements in HTML
Pages itself instead of having a separate CGI files.
JSTL works with request attributes- they are most often set in the request by a Servlet,
which forwards to the Jsp.
Centralization of information: As a one-shot portal for public information on government programmes, the Jsp can advance the objective of transparency.
That is,
Servlets are fully Server Oriented, and together with Jsp meet the requirements related to making Web
Pages Dynamic on the Server Side.
Performance is significantly better because the Jsp allows dynamic elements to be incorporated into the HTML pages themselves,
instead of having separate CGI files.
The outcome of this alignment effort has been the Unified Expression Language(EL),
which integrates the expression languages defined by Jsp 2.0 and JSF 1.1.
If you want to invoke some Java code to control the flow inside a Jsp page, then you need to grab an(existing)
flow control taglib like JSTL core.
This includes pages created by client-side scripting, and ones created by server-side scripting(such as PHP,
Perl, Jsp or ASP. NET)
where the web server generates content before sending it to the client.
Jsp pages are loaded in the server
and operated from a structured special installed Java server packet called a J2EE Web Application often packaged as a. war or. ear file archive.
Jsp tags can be used for several purposes,
such as retrieving information from a database or registering user preferences, accessing JavaBeans components, passing control between pages and sharing information between requests, pages, etc.

JavaServer Pages(Jsp) is a technology for developing web
pages that support dynamic content which helps developers insert java code in HTML pages by making use of special Jsp tags, most of which start with<% and end with%.
