THE FIRST DYNAMIC WEB APPLICATION PROJECT WITH ECLIPSE AND TOMCAT
You can develop
dynamic content web projects with tomcat. This example illustrates the opening
dynamic web project and the important folders and files. First of all we
installed tomcat to eclipse before and now we will create a new dynamic web
project.
First of all open
your eclipse and click to FileàNewàDynamic Web Project. If there is not a Dynamic Web
Project on the tab you can select other and find dynamic web project in there.

There will be
some folders such as in picture 3. As you can see in picture 3, there is a java
resources file into the main folder root. The src folder in this folder will
contain your java files such as servlets, beans, pojos, db classes etc... and
near the src folder there will be a library which is Libraries that will
contain JRE system libraries that your project will work on. As an example if
your project will work on Java 1.5 this folder will contain Java 1.5 related
jars.
The
other important Folder is WebContent folder that will contain your front end
files such as jsp, html... there is one folder that is specialized as WEB-INF, which contains unreachable files according to user. If you notice that i selected the Generate web.xml file while i was opening the
project. This creates our projects web.xml
file into the WEB-INF folder. This contains the project contents. Important
from the point of project working structure. Web.xml will be defined later.
Also there is a lib folder that can contain your external utilities.
Now lets create
an hello.jsp into the WebContent folder.(Right click on this folder and choose
new Jsp)

There will be
default codes such as
<%@ page language="java" contentType="text/html;
charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html
PUBLIC "-//W3C//DTD
HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type"
content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
</body>
</html>
You will customize the codes according to your needs. Now
only change the Insert title here to Hello
And add Hello between the <body> and </body>
tags.
And add to your tomcat such as in picture 4. You can right
click to your tomcat in the server tab and then click to Add and Remove then
add your project. And then you can start your server with right click then
start.It will deploy your project. After starting successfully open a browser
then type
http:/{Your Project Name}/{Folders if there is/}your page
then you can see your result page such as in Picture 5 but if you can not see
anythink you should check your server installation or there can be a problem
about deploying your project.
