app-profile-jee-jsp: JSP Profile Application

Level: Beginner Technologies: JavaEE Summary: JSP Profile Application Target Product: Keycloak, WildFly Source: https://github.com/keycloak/keycloak-quickstarts

What is it?

The app-profile-jee-jsp quickstart demonstrates how to write an application with JavaEE that authenticates using Keycloak. Once authenticated the application shows the users profile information and can also display the token retrieved from Keycloak.

System Requirements

If you are deploying the application as a WAR you need to have WildFly 10 running.

All you need to build this project is Java 8.0 (Java SDK 1.8) or later and Maven 3.1.1 or later.

Configuration in Keycloak

Prior to running the quickstart you need to create a client in Keycloak and download the installation file.

The following steps shows how to create the client required for this quickstart:

  • Open the Keycloak admin console
  • Select Clients from the menu
  • Click Create
  • Add the following values:
    • Client ID: You choose (for example app-profile-jsp)
    • Client Protocol: openid-connect
    • Root URL: URL to the application (for example http://localhost:8080/app-profile-jsp)
  • Click Save

Once saved you need to change the Access Type to confidential and click Save.

If you deploy the application somewhere else change the hostname and port of the URLs accordingly.

Finally you need to configure the adapter, this is done by retrieving the adapter configuration file:

  • Click on Installation in the tab for the client you created
  • Select Keycloak OIDC JSON
  • Click Download
  • Move the file keycloak.json to the src/main/webapp/ directory in the root of the quickstart

As an alternative you can create the client by importing the file client-import.json and copying config/keycloak-example.json to src/main/webapp/keycloak.json.

Build and Deploy the Quickstart

  1. Open a terminal and navigate to the root directory of this quickstart.

  2. The following shows the command to deploy the quickstart:

    mvn clean wildfly:deploy

If you prefer to secure WARs via Keycloak subsystem:

mvn install -Dsubsystem wildfly:deploy

Access the Quickstart

You can access the application with the following URL: http://localhost:8080/app-profile-jsp

Undeploy the Quickstart

  1. Open a terminal and navigate to the root of the Keycloak server directory.

  2. The following shows the command to undeploy the quickstart:

    mvn install wildfly:undeploy
