Summary: The h2-console quickstart demonstrates how to use the H2 Console that is bundled with and built specifically for JBoss EAP.
Target Product: JBoss EAP
Source: https://github.com/jboss-developer/jboss-eap-quickstarts/
Red Hat JBoss Enterprise Application Platform bundles H2 as an in-memory, in-process database. H2 is written in Java so it can run on any platform that JBoss EAP runs on.
The h2-console quickstart comes bundled with a version of the H2 Console built for JBoss EAP. To make the H2 console run on JBoss EAP, the H2 libraries were removed from the WAR and a dependency on the H2 module was added to the META-INF/MANIFEST.MF file. The rebuilt console is provided in the root directory of this quickstart.
This quickstart demonstrates how to use the H2 console with Red Hat JBoss Enterprise Application Platform. It uses the greeter quickstart as a GUI for entering data.
Note: This quickstart uses the H2 database included with Red Hat JBoss Enterprise Application Platform 7. It is a lightweight, relational example datasource that is used for examples only. It is not robust or scalable, is not supported, and should NOT be used in a production environment!
The application this project produces is designed to be run on Red Hat JBoss Enterprise Application Platform 7 or later.
All you need to build this project is Java 8.0 (Java SDK 1.8) or later and Maven 3.1.1 or later. See Configure Maven for JBoss EAP 7 to make sure you are configured correctly for testing the quickstarts.
This quickstart depends on the deployment of the greeter quickstart. Before running this quickstart, see the greeter README file for details on how to deploy it.
You can verify the deployment of the greeter quickstart by accessing the following URL: http://localhost:8080/jboss-greeter
When you have completed testing this quickstart, see the greeter README file for instructions to undeploy the archive.
In the following instructions, replace EAP7_HOME with the actual path to your JBoss EAP installation. The installation path is described in detail here: Use of EAP7_HOME and JBOSS_HOME Variables.
Deploy the console by copying the h2console.war located in the root directory of this quickstart to the EAP7_HOME/standalone/deployments directory.
You can access the console at the following URL: http://localhost:8080/h2console.
You need to enter the JDBC URL, and credentials. To access the "test" database that the greeter quickstart uses, enter these details:
- JDBC URL:
jdbc:h2:mem:greeter-quickstart;DB_CLOSE_ON_EXIT=FALSE;DB_CLOSE_DELAY=-1 - User Name:
sa - Password:
sa
Click on the Test Connection button to make sure you can connect. If you can, go ahead and click Connect.
Take a look at the data added by the greeter application. Run the following SQL command:
select * from users;
You should see the two users seeded by the greeter quickstart, plus any users you added when testing that application.
To undeploy this example, simply delete the h2console.war from the EAP7_HOME/standalone/deployments directory.
cd EAP7_HOME/standalone/deployments
rm h2console.war
