Summary: The helloworld-mbean
quickstart demonstrates the use of CDI and MBean in WildFly and includes JConsole instructions and Arquillian tests.
Target Product: WildFly
Source: https://github.com/wildfly/quickstart/
The helloworld-mbean
quickstart demonstrates the use of CDI and MBean in WildFly Application Server. The project also includes a set of Arquillian tests for MBeans.
The example is composed of the following MBeans:
AnnotatedComponentHelloWorld
: This MBean is a managed bean with @MXBean
annotation.
MXComponentHelloWorld
: This MBean is a managed bean with MXBean
interface.
MXPojoHelloWorld
: This MBean is a pojo using MXBean interface and declared in the jboss-service.xml
file.
SarMXPojoHelloWorld
: This MBean is a pojo using MXBean interface and declared in jboss-service.xml in SAR packaging.
The application this project produces is designed to be run on WildFly Application Server 11 or later.
All you need to build this project is Java 8.0 (Java SDK 1.8) or later and Maven 3.3.1 or later. See Configure Maven for WildFly 11 to make sure you are configured correctly for testing the quickstarts.
In the following instructions, replace WILDFLY_HOME
with the actual path to your WildFly installation. The installation path is described in detail here: Use of WILDFLY_HOME and JBOSS_HOME Variables.
For Linux: WILDFLY_HOME/bin/standalone.sh
For Windows: WILDFLY_HOME\bin\standalone.bat
mvn clean install wildfly:deploy
This will deploy helloworld-mbean-webapp/target/helloworld-mbean-webapp.war
and helloworld-mbean-service/target/helloworld-mbean-service.sar
to the running instance of the server.
This quickstart differs from the other quickstarts in that it uses JConsole to access and test the quickstart rather than access an URL in the browser. If you do access http://localhost:8080/helloworld-mbean-webapp/, you will see a screen shot image of the JConsole application,
The following sections describe how to use JConsole to inspect and test the MBeans.
To connect to the WildFly server using JConsole, open a command prompt and type the following command :
For Linux: JDK_HOME/bin/jconsole
For Windows: JDK_HOME\bin\jconsole.exe
Select the local org.jboss.modules.Main
process and click Connect
.
A dialog displays with the warning Secure connection failed. Retry insecurely?
. Click Insecure
to continue.
You can use JConsole to inspect and use the MBeans :
quickstarts
in the left column of the console.quickstarts
, you see the 4 MBeans: AnnotatedComponentHelloWorld
, MXComponentHelloWorld
, MXPojoHelloWorld
, and SarMXPojoHelloWorld
Operations
--> sayHello
.sayHello
button.AnnotatedComponentHelloWorld
and MXComponentHelloWorld
examples, you will see a popup Window displaying Hello <your name>!
.MXPojoHelloWorld
and SarMXPojoHelloWorld
examples, you will see a popup Window displaying Welcome <your name>!
.mvn wildfly:undeploy
This quickstart provides Arquillian tests. By default, these tests are configured to be skipped as Arquillian tests require the use of a container.
mvn clean verify -Parq-remote
You can also let Arquillian manage the WildFly server by using the arq-managed
profile. For more information about how to run the Arquillian tests, see Run the Arquillian Tests.
You can also start the server and deploy the quickstarts or run the Arquillian tests from Eclipse using JBoss tools. For general information about how to import a quickstart, add a WildFly server, and build and deploy a quickstart, see Use JBoss Developer Studio or Eclipse to Run the Quickstarts.
This quickstart consists of multiple projects and requires installation of the JBoss Tools Maven Packaging Configurator
, so it deploys and runs differently in JBoss Developer Studio than the other quickstarts.
