The document discusses Java Server Pages (JSP). Some key points:
- JSP is a server-side technology that allows creating dynamic web applications using Java code and HTML/XML pages.
- JSP pages can access the full Java API and are compiled into servlets, allowing them to connect to databases and integrate with other Java technologies.
- A JSP page consists of HTML tags, JSP tags, and scriptlets containing Java code. The life cycle of a JSP page involves compilation, initialization, execution, and cleanup similar to servlets.
- JSP offers advantages over plain servlets like easier maintenance and faster development since logic is separated from presentation.

JSP technology has facilitated the segregation of the work of a Web designer and a Web developer.
A Web designer can design and formulate the layout for the Web page by using HTML.
On the other hand, a Web developer working independently can use java code and other JSP specific tags to code the business logic.
The simultaneous construction of the static and dynamic content facilitates development of quality applications with increased productivity.

If you want to earn much in web development business, you also need to learn Java web technologies.
Java has de facto standart frameworks such as EJB 3.0, Spring and others that can be bound to them.
But at heart, they all use the similar JSP/Servlet technology and add some layers above them to speed up the development.
You will use them in your daily business but before using them, you must learn the basics and what is going on while using them. Otherwise, you will not be able to find a proper solution to common problems.
This course will make you understand the basics of JSP / servlet technlogies, designing a relational database, DB operations, design patterns, working with other developers,
and let you know the must-do operations in professional projects such as performance increasing, logging errors.
If you want to develop a web-site in a couple of hours without understanding what you are doing, you may go ahead and find other resources. But if you really want to understand what you are doing and learn the theory at the same time, this course will be a great oppurtunity for you. You will develop a real working project. Yow will first write quick and dirty code then you will apply professional patterns one by one while investigating the problems.
You will walk through a real development flow:
1- Write a quick and dirty code for doing the job.
2- You will design database tables and high performance queries
3 - You will apply design patterns to make the code reusable and high performance.
4 - You will beautify the user interface with Javascript and CSS tweaks
5- You will add exception handling, logging mechanism for production environment

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

2. JSP
Java Server Pages (JSP) is a server-side programming technology that enables
the creation of dynamic, platform-independent method for building Web-
based applications.
JSP have access to the entire family of Java APIs, including the JDBC API to
access enterprise databases. This will teach you how to use Java Server Pages
to develop your web applications in simple and easy steps.
A JSP page consists of HTML tags and JSP tags.
The JSP pages are easier to maintain than Servlet because we can separate
designing and development.
It provides some additional features such as Expression Language, Custom
Tags, etc.
3. Why to Learn JSP?
JavaServer Pages often serve the same purpose as programs implemented using the Common Gateway
Interface (CGI). But JSP offers several advantages in comparison with the CGI.
Performance is significantly better because JSP allows embedding Dynamic Elements in HTML Pages itself
instead of having separate CGI files.
JSP are always compiled before they are processed by the server unlike CGI/Perl which requires the server
to load an interpreter and the target script each time the page is requested.
JavaServer Pages are built on top of the Java Servlets API, so like Servlets, JSP also has access to all the
powerful Enterprise Java APIs, including JDBC, JNDI, EJB, JAXP, etc.
JSP pages can be used in combination with servlets that handle the business logic, the model supported
by Java servlet template engines.
Finally, JSP is an integral part of Java EE, a complete platform for enterprise class applications. This means
that JSP can play a part in the simplest applications to the most complex and demanding.
4. Advantages of JSP over Servlet
1) Extension to Servlet
2) Easy to maintain
3) Fast Development
4) Less code than Servlet
7. JSP PROCESSING
The following steps explain how the web server creates the Webpage using JSP −
As with a normal page, your browser sends an HTTP request to the web server.
The web server recognizes that the HTTP request is for a JSP page and forwards it to a JSP engine. This is done by
using the URL or JSP page which ends with .jsp instead of .html.
The JSP engine loads the JSP page from disk and converts it into a servlet content. This conversion is very simple
in which all template text is converted to println( ) statements and all JSP elements are converted to Java code.
This code implements the corresponding dynamic behavior of the page.
The JSP engine compiles the servlet into an executable class and forwards the original request to a servlet engine.
A part of the web server called the servlet engine loads the Servlet class and executes it. During execution, the
servlet produces an output in HTML format. The output is furthur passed on to the web server by the servlet
engine inside an HTTP response.
The web server forwards the HTTP response to your browser in terms of static HTML content.
Finally, the web browser handles the dynamically-generated HTML page inside the HTTP response exactly as if it
were a static page.
11. JSP Initialization
When a container loads a JSP it invokes the jspInit() method before
servicing any requests. If you need to perform JSP-specific initialization,
override the jspInit() method −
public void jspInit(){
// Initialization code...
}
Typically, initialization is performed only once and as with the servlet init
method, you generally initialize database connections, open files, and
create lookup tables in the jspInit method.
12. JSP Execution
This phase of the JSP life cycle represents all interactions with
requests until the JSP is destroyed.
Whenever a browser requests a JSP and the page has been loaded
and initialized, the JSP engine invokes the _jspService() method in
the JSP.
The _jspService() method takes an HttpServletRequest and
an HttpServletResponse as its parameters as follows −
void _jspService(HttpServletRequest request, HttpServletResponse
response) {
// Service handling code...
}
13. JSP Cleanup
The destruction phase of the JSP life cycle represents when a JSP is
being removed from use by a container.
The jspDestroy() method is the JSP equivalent of the destroy
method for servlets. Override jspDestroy when you need to
perform any cleanup, such as releasing database connections or
closing open files.
The jspDestroy() method has the following form −
public void jspDestroy() {
// Your cleanup code goes here.
}
16. Creating a simple JSP Page
index.jsp:Let's see the simple example of JSP where we are using the scriptlet tag to
put Java code in the JSP page. We will learn scriptlet tag later.
<html>
<body>
<% out.print(2*5); %>
</body>
</html>
It will print 10 on the browser.
17. How to run a simple JSP Page?
Start the server
Put the JSP file in a folder and deploy on the server
Visit the browser by the URL http://localhost:portno/contextRoot/jspfile,
for example, http://localhost:8888/myapplication/index.jsp
18. JSP Declarations
<%! int i = 0; %>
<%! int a, b, c; %>
<%! Circle a = new Circle(2.0); %>
20. JSP Directives
A JSP directive affects the overall structure of the servlet class. It usually has the
following form −
<%@ directive attribute="value" %>
There are three types of directive tag −
S.No. Directive & Description
1
<%@ page ... %>
Defines page-dependent attributes, such as scripting language, error page, and buffering requirements.
2
<%@ include ... %>
Includes a file during the translation phase.
3
<%@ taglib ... %>
Declares a tag library, containing custom actions, used in the page
21. JSP Actions
JSP actions use constructs in XML syntax to control the behavior
of the servlet engine. You can dynamically insert a file, reuse
JavaBeans components, forward the user to another page, or
generate HTML for the Java plugin.
There is only one syntax for the Action element, as it conforms to
the XML standard −
<jsp:action_name attribute="value" />
22. JSP Implicit Objects
S.No. Object & Description
1
request
This is the HttpServletRequest object associated with the request.
2
response
This is the HttpServletResponse object associated with the response to the client.
3
out
This is the PrintWriter object used to send output to the client.
4
session
This is the HttpSession object associated with the request.
5
application
This is the ServletContext object associated with the application context.
6
config
This is the ServletConfig object associated with the page.
7
pageContext
This encapsulates use of server-specific features like higher performance JspWriters.
8
page
This is simply a synonym for this, and is used to call the methods defined by the translated servlet class.
Exception
23. JSP - Form Processing
The Methods in Form Processing
GET method
The GET method sends the encoded user information appended to the page request. The page and the encoded information are
separated by the ? character as follows −
http://www.test.com/hello?key1=value1&key2=value2
The GET method is the default method to pass information from the browser to the web server and it produces a long string that
appears in your browser's Location:box. It is recommended that the GET method is better not used. if you have password or other
sensitive information to pass to the server.
The GET method has size limitation: only 1024 characters can be in a request string.
This information is passed using QUERY_STRING header and will be accessible through QUERY_STRING environment variable
which can be handled using getQueryString() and getParameter() methods of request object.
POST method
A generally more reliable method of passing information to a backend program is the POST method.
This method packages the information in exactly the same way as the GET method, but instead of sending it as a text string after a ?
in the URL it sends it as a separate message. This message comes to the backend program in the form of the standard input which
you can parse and use for your processing.
JSP handles this type of requests using getParameter() method to read simple parameters and getInputStream() method to read
binary data stream coming from the client
24. Reading Form Data using JSP
getParameter() − You call request.getParameter() method to get the value of a
form parameter.
getParameterValues() − Call this method if the parameter appears more than
once and returns multiple values, for example checkbox.
getParameterNames() − Call this method if you want a complete list of all
parameters in the current request.
getInputStream() -− Call this method to read binary data stream coming from
the client.
