Servlet Essentials

Hi there,

Straight away, we want to start Servlet codings. Consider we already have Java basics which are Java Core and basics of JavaBeans. We also already have the complete environment settings. What to do then?

Follow the steps:

1. Get to know to javax.servlet package. It contains all the classes & interfaces to build servlets. Google it for more info.
2. GenericServlet (which is in Servlet API) class to be extended hence, inherited by our class. This class provides functionality that makes it easy to handle requests & responses.

Running Servlet from Netbeans

This tutorial assuming you are going to create a project using JSP + Servlet + Javabeans

Starting:

1. Open Netbeans.

Creating a project (if you do not have one yet or you wish to have a new one):

1. File > New Project. "New Project" window appears.
2. In the "Choose Project" step, choose Java Web > Web Application. Click Next.
3. In the "Name and Location" step, enter your "Project Name". In this case, we use 'MyServlet'. You may locate your Project Location & Project Folder. We are going to use the default. Click Next.
4. In the "Server and Settings" step, choose your Apache Tomcat server. I'm going to use 'Java EE 5' for "Java EE version".
5. We are not going to use any "Frameworks". Just click Finish.

Your project will be created and opened. See that in "Projects" window.

Creating a servlet file:

1. In the "Project" window, right click your project name node. In our case, it is 'MyServlet'. Choose New > Servlet. "New Servlet" window appears.
2. It is directly goes to second step which is "Name and Location". Put yours. We are going to use 'MyServletFile'. Click Next.
3. Leave the default settings in the "Configure Servlet Deployment". Click Finish.

There goes your 1st servlet file. Refer image below:
