Install, Configure, and Verify

To verify that Developer Studio and JBoss EAP are working correctly, deploy and execute the helloworld quickstart application in the JBoss EAP server you will now create and configure:

In Developer Studio, Open the Red Hat Central view.

1. Note: If the Red Hat Central view is not visible, click the

    icon on the main menu bar.

2. Type helloworld into the search box and click the helloworld-rs quickstart shown in the result.

   

    

3. Click Finish. This downloads the helloworld application and its Maven dependencies.

4. Once all the dependencies are downloaded, a dialog appears to tell you that your project is ready. Click Finish.

5. In the Servers tab, select Red Hat JBoss EAP 7.0 [Stopped] and click the Start the Server icon to start the JBoss EAP server.

   

6. Once the server starts, right-click the jboss-helloworld application in the Project Explorer view.

   1. From the menu that appears, select Run as.. and then Run on Server.

   2. Select the newly created JBoss EAP server, click OK and then Finish.

This will build, deploy, and run the helloworld application in the JBoss EAP server. The application opens in the internal default Developer Studio web browser and presents the "Hello World!" Success page.

Build your first JBoss EAP application

Follow the below series to build your first application. You will build some simple examples as well as build a TicketMonster Application using JBoss EAP. The TicketMonster application shows you how to build a modern HTML application that communicates with a Jakarta EE backend using REST. The series walks you through each step of the application development lifecycle, from start to finish.
