ToDo Web Application

This file gives more details about my to-do list web application and tracks my progress in this project. Aim:

The aim of this project is to learn to develop a web application without using any IDE. Earlier I have developed various web applications using Eclipse and netBeans, so this time I wish to learn deeper. This project will also revise my knowledge to develop a simple web application. Later, I plan to make its various versions to learn latest technologies like single page applications. I will also learn about databases by connecting this application with SQL and NoSQL databases. The full learning plan will be posted soon.

Quick Java web project with Maven

Step 1:

Create a web project using Maven template. Go to the folder you want to create the project and type this command

> mvn archetype:generate -DgroupId={project-packaging} -DartifactId={project-name} -DarchetypeArtifactId=maven-archetype-webapp -DinteractiveMode=false

For example I typed

> mvn archetype:generate -DgroupId=com.shubhangi -DartifactId=ToDoApp -DarchetypeArtifactId=maven-archetype-webapp -DinteractiveMode=false

and it created a maven project with some standard directory structure. When I used command tree, it gave me following structure:

.
|--- pom.xml
|--- src
       |--- main
              |--- resources
              |--- webapp
                     |--- WEB-INF
                     |       |--- web.xml
                     |--- index.jsp

Step 2:

I updated web.xml to support Servlet 2.5. Now my web.xml looks like this.

<web-app xmlns="http://java.sun.com/xml/ns/javaee"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
	      http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	version="2.5">
  <display-name>Archetype Created Web Application</display-name>
</web-app>

Step 3:

I added tomcat plugin to pom.xml.

<!-- For Maven Tomcat Plugin -->
		  <plugin>
			<groupId>org.apache.tomcat.maven</groupId>
			<artifactId>tomcat7-maven-plugin</artifactId>
			<version>2.2</version>
			<configuration>
				<path>/CounterWebApp</path>
			</configuration>
		  </plugin>

Step 4:

Now, the basic Hello World project set up is ready. To compile and package the project into a WAR file, use command

>mvn package

And to run the project, use following command

>mvn tomcat:run

As I have added tomcat plugin to our pom.xml, this command started tomcat and deployed the project to http://localhost:8080/ToDoApp
