Create a new dynamic web project by selecting the File > New > Dynamic Web Project menu entry and enter the following information:

• Name: weatherapp
• Target Runtime: Java Web
• Dynamic Web Module Version: 2.5

Click on Next

Remove the standard src Source folder and add a new one called src/main/java to create a project that adheres to the standard Maven Directory Layout.

Change the default output folder to target/classes

Click on Next.

Change the Content Directory from WebContent to src/main/webapp (again, to adhere to Maven conventions)

Click on Finish.

Make sure you have your weatherapp project folder selected, and then create a new Servlet by selecting the File > New > Servlet menu entry and enter the following information:

• Package name: com.sap.hana.cloud.samples.weatherapp.web
• Class name: HelloWorldServlet

Click on Next.

Change the URL Mapping from /HelloWorldServlet to /hello to make it a bit easier to memorize.

Click on Finish and the HelloWorldServlet.java file will open in the editor.

Now we need to do our first bit of coding. Navigate to the servlet’s doGet() method and replace the TODO comment with the following line of code and save your changes:

response.getWriter().println("Hello World!");

Deploy the application to your local server by using the Run as > Run on Server context menu of the HelloWorldServlet node in the Project Explorer view.

Choose the Manually define a new Server option and select the SAP / Java Web Server option from the server selection. Make sure to select Java Web as the server runtime environment.

Click on Finish. The internal browser is now started and displays the traditional message marking the first step into a new programmer’s journey.
