deltaspike-deactivatable: Example Using DeltaSpike Deactivatable

What is it?

The deltaspike-deactivatable quickstart demonstrates how to use DeltaSpike ClassDeactivator to manually deactivate artifacts. This can improve the performance if a part isn't needed, provide a custom implementation if the default implementation isn't pluggable by default, or bypass an implementation which causes an issue.

To deactivate a class you need to implement ClassDeactivator. Returning 'false' or 'true' allows to deactivate or activate the class in question. This project has a ClassDeactivator that deactivates the ExcludeExtension. If the ExcludeExtension is deactivated then MyBean, which is annotated with @Exclude, won't be excluded

System requirements

The application this project produces is designed to be run on Red Hat JBoss Enterprise Application Platform (EAP) 6.1 or later with the Red Hat JBoss Web Framework Kit (WFK) 2.7.

All you need to build this project is Java 6.0 (Java SDK 1.6) or later, Maven 3.0 or later.

Configure Maven

If you have not yet done so, you must Configure Maven before testing the quickstarts.

Start the JBoss EAP Server

  1. Open a command line and navigate to the root of the JBoss EAP directory.
  2. The following shows the command line to start the server with the default profile:

     For Linux:   EAP_HOME/bin/
     For Windows: EAP_HOME\bin\standalone.bat

Run the Arquillian Tests

This quickstart provides Arquillian tests. By default, these tests are configured to be skipped as Arquillian tests require the use of a container.

NOTE: The following commands assume you have configured your Maven user settings. If you have not, you must include Maven setting arguments on the command line. See Run the Arquillian Tests for complete instructions and additional options.

  1. Make sure you have started the JBoss EAP server as described above.
  2. Open a command line and navigate to the root directory of this quickstart.
  3. Type the following command to run the test goal with the following profile activated:

     mvn clean test -Parq-jbossas-remote

NOTE: If you use the Maven settings command line argument with this quickstart, you need to pass an additional argument to allow ShrinkWrap Resolver to function properly:

mvn clean test -Parq-jbossas-remote -s /path/to/custom/settings.xml -Dorg.apache.maven.user-settings=/path/to/custom/settings.xml

Run tests from JBDS

To be able to run the tests from JBDS, first set the active Maven profile in project properties to be either 'arq-jbossas-managed' for running on managed server or 'arq-jbossas-remote' for running on remote server.

To run the tests, right click on the project or individual classes and select Run As –> JUnit Test in the context menu.

When the tests are run, statements are written to the server log as follows:

Run the Quickstart in JBoss Developer Studio or Eclipse

You can also start the server and deploy the quickstarts from Eclipse using JBoss tools. For more information, see Use JBoss Developer Studio or Eclipse to Run the Quickstarts

Debug the Application

If you want to debug the source code or look at the Javadocs of any library in the project, run either of the following commands to pull them into your local repository. The IDE should then detect them.

    mvn dependency:sources
    mvn dependency:resolve -Dclassifier=javadoc
