If you don't have an Azure subscription, create a free account before you begin.

Don't forget to clean up the resources after you complete this tutorial. In that case, running this guide will not exceed your free account quota.

Prerequisites

Install and sign-in

The following steps walk you through the Azure sign-in process in your IntelliJ development environment.

  1. If you haven't installed the plugin, see Azure Toolkit for IntelliJ.

  2. To sign in to your Azure account, navigate to the left-hand Azure Explorer sidebar, and then click the Azure Sign In icon. Alternatively, you can navigate to Tools, expand Azure, and then click Azure Sign in.

  3. In the Azure Sign In window, select OAuth 2.0, and then click Sign in. For other sign-in options, see Sign-in instructions for the Azure Toolkit for IntelliJ.

  4. In the browser, sign in with your account and then go back to IntelliJ. In the Select Subscriptions dialog box, click on the subscription that you want to use, then click Select.

Create a new web app project

  1. Click File, expand New, and then click Project.

  2. In the New Project dialog box, select Maven, and make sure the Create from Archetype option is checked. From the list, select maven-archetype-webapp, and then click Next.

    Select the maven-archetype-webapp option.

  3. Expand the Artifact Coordinates dropdown to view all input fields. Specify the following information for your new web app, and then click Next:

    • Name: The name of your web app. This value will be used to automatically fill in the web app's ArtifactId field.
    • GroupId: The name of the artifact group, usually a company domain, such as com.microsoft.azure.
    • Version: We'll keep the default version 1.0-SNAPSHOT.

  4. Customize any Maven settings or accept the defaults, and then click Finish.

  5. To find the generated code, navigate to your project on the left-hand Project tab, then open the file src/main/webapp/index.jsp. You will see code similar to the following example.

    <html>
 <body>
   <h2>Hello World!</h2>
 </body>
</html>

    Open the index.jsp file.

Deploy web app to Azure

  1. Under the Project Explorer view, right-click your project, expand Azure, then click Deploy to Azure Web Apps.

  2. In the Deploy to Azure dialog box, you can deploy the application to an existing Tomcat webapp or you can create a new one.

    a. Click + to create a new webapp. Otherwise, choose WebApp from the WebApp dropdown if there are existing webapps in your subscription.

    Deploy to Azure dialog window.

    b. In the pop-up Create WebApp dialog box, specify the following information and click OK:

    • Name: The WebApp's domain name. This value should be unique across Azure.
    • Platform: Select Linux-Java 8-TOMCAT 9.0 or as appropriate.

    c. To deploy to an existing webapp, choose the web app from WebApp drop down, and then click Run.

  3. The toolkit will display a status message when it has successfully deployed your web app, along with the URL of your deployed web app if succeed.

    Edit configuration menu.

  2. On the Run/Debug Configurations dialog box, you can modify any of the default settings. Click OK to save the settings.

Clean up resources

  1. To delete your web app, navigate to the left-hand Azure Explorer sidebar and locate the Web Apps item.

    Note

    If the Web Apps menu item does not expand, manually refresh the list by clicking the Refresh icon on the Azure Explorer toolbar, or by right-clicking the Web Apps menu item and selecting Refresh.

  2. Right-click the web app you'd like to delete and click Delete.
