Servlet EchoBot

This demonstrates how to create a Bot using the Bot Framework 4 SDK Preview for Java in Azure.

This sample is a Java Servlet app and uses the Azure CLI and azure-webapp Maven plugin to deploy.

Prerequisites

• Install Maven
• An account on Azure

Deploy the bot to Azure

As described on Deploy your bot, you will perform the first 4 steps to setup the Azure app, then deploy the code using the azure-webapp Maven plugin.

1. Login to Azure

From a command (or Powershell) prompt in the root of the bot folder, execute:
az login

2. Set the subscription

az account set --subscription "<azure-subscription>"

If you aren't sure which subscription to use for deploying the bot, you can view the list of subscriptions for your account by using az account list command.

3. Create an App registration

az ad app create --display-name "<botname>" --password "<appsecret>" --available-to-other-tenants

Replace <botname> and <appsecret> with your own values.

<botname> is the unique name of your bot.
<appsecret> is a minimum 16 character password for you bot.

Record the appid from the returned JSON

4. Create the Azure resources

Replace the values for <appid>, <appsecret>, <botname>, and <groupname> in the following commands:

To a new Resource Group

az deployment sub create --name "echoBotDeploy" --location "westus" --template-file ".\deploymentTemplates\template-with-new-rg.json" --parameters appId="<appid>" appSecret="<appsecret>" botId="<botname>" botSku=S1 newAppServicePlanName="echoBotPlan" newWebAppName="echoBot" groupLocation="westus" newAppServicePlanLocation="westus"

To an existing Resource Group

az deployment group create --resource-group "<groupname>" --template-file ".\deploymentTemplates\template-with-preexisting-rg.json" --parameters appId="<appid>" appSecret="<appsecret>" botId="<botname>" newWebAppName="echoBot" newAppServicePlanName="echoBotPlan" appServicePlanLocation="westus" --name "echoBot"

5. Update app id and password

In src/main/resources/application.properties update

• MicrosoftAppPassword with the appsecret value
• MicrosoftAppId with the appid from the first step

6. Deploy the code

• Execute mvn clean package
• Execute mvn azure-webapp:deploy -Dgroupname="<groupname>" -Dbotname="<botname>"

If the deployment is successful, you will be able to test it via "Test in Web Chat" from the Azure Portal using the "Bot Channel Registration" for the bot.

After the bot is deployed, you only need to execute #6 if you make changes to the bot.
