Weather360

This is a weather app which addresses the need for a fast and easy to manage article system, while providing a focus on weather and climate information.

• It uses the following Azure Services: Azure Virtual Machine, Azure Text-To-Speech.
• The backend is coded using Java Servlet, Tomcat Server, JDBC db connection, MySQL database, JSP for frontend.

Setup on Azure

1. Create a Linux VM for running the application backend and storing the MySQL database.

2. Create an API key for accessing the Azure Speech Services.

Navigate to article.jsp and paste in your Azure Speech Services Key in the following code block:

        try {
            fetch("https://eastus.tts.speech.microsoft.com/cognitiveservices/v1", {
              method: "POST",
              headers: {
                "Ocp-Apim-Subscription-Key": "",
                "Content-Type": "application/ssml+xml",
                "X-Microsoft-OutputFormat": "audio-16khz-128kbitrate-mono-mp3",
              },
              body: `<speak version='1.0' xml:lang='en-US'>
                     <voice xml:lang='en-US' xml:gender='Female' name='en-US-JennyNeural'>
                         ${textContent}
                     </voice>
                 </speak>`,
            })
              .then((response) => response.arrayBuffer())
              .then((arrayBuffer) => {
                var blob = new Blob([arrayBuffer], { type: 'audio/mp3' });
                var url = URL.createObjectURL(blob);
                var audio = new Audio();
                audio.src = url;
                audio.play();
              })
              .catch((error) => {
                console.error("Error:", error);
                alert("Oops! An error occurred.");
              });
          } catch (error) {
            console.error("Error:", error);
            alert("Oops! An error occurred.");
          }

Note: API keys used for the deployment of the demo have been removed from this git repo for security reasons.

Setup Java Project

• Clone the repo

  git clone https://github.com/priyanka-maz/Weather360

• Make sure MySQL is installed. We assume user:'root', password:'abcd'.

• Make sure Apache Tomcat 9.0.x is installed.

Using Eclipse

1. Import project into Eclipse.

2. Setup tomcat server on any available port (say, 8080).

Using jre directly (such as on a Linux VM on Azure)

1. Export WAR file from Eclipse.

2. Install tomcat-9.0.x server following instructions given at https://www.digitalocean.com/community/tutorial_collections/how-to-install-apache-tomcat

3. Navigate to tomcat manager and upload and deploy WAR file.

Note: Navigate to /Startup to have the application automatically create the database and tables for you.
