What is it?

This project demonstrates how to use CDI Scopes @PortletLifecycleScoped and @PortletRedisplayScoped in Portlets.

An introduction and some background information to this quickstart can be found in the following chapters of Red Hat JBoss Portal Developer Guide:

• Starting a Portlet Project
• Standard Portlet Development (JSR-286)
• CDI Portlet Development
• Portlet CDI Scopes

System Requirements

All you need to build this example project is Java 6.0 (Java SDK 1.6) or newer and Maven 3.0 or newer.

The project is designed to be deployed on Red Hat JBoss Portal 6.2 running on JBoss EAP.

Configure Maven

You have two options how you can configure Maven: A. Use hosted Maven repository or B. Download & setup zipped Maven repository.

A. Use hosted Maven repository

This is the easier and thus recommended option. You need to configure the Maven user settings as follows:

• Look for the settings.xml file in the ${user.home}/.m2/ directory. For example:

    For Linux or Mac: ~/.m2/settings.xml
    For Windows:       \Users\USER_NAME\.m2\settings.xml or \Documents and Settings\USER_NAME\.m2\settings.xml
  

• If you have an existing settings.xml file, modify it with the configuration information from the settings-hosted-repo.xml file located in the root folder of Red Hat JBoss Portal quickstarts. This effectivelly results in adding http://maven.repository.redhat.com/techpreview/all as <repository> and <pluginRepository> to your settings.xml.

• If there is no settings.xml file, copy the settings-hosted-repo.xml file to the .m2 directory for your operating system and rename it to settings.xml.

B. Download & setup zipped Maven repositories

1. Download the following zipped Maven repositories from Red Hat Customer Portal, Downloads > JBoss Enterprise Middleware:

   • Red Hat JBoss Portal 6.2.0 Maven Repository
   • Red Hat JBoss Portal 6.1.1 Maven Repository
   • JBoss Portal Platform 6.1.0 Maven Repository
   • JBoss Enterprise Portal Platform (EPP) 6.0.0 Maven Repository
   • Web Framework Kit 2.4.0 Maven Repository
   • Web Framework Kit 2.3.0 Maven Repository
   • Web Framework Kit 2.2.0 Maven Repository
   • Web Framework Kit 2.1.0 Maven Repository
   • Web Framework Kit 2.0.0 Maven Repository
   • Application Platform 6.4.0 Maven Repository
   • Application Platform 6.2.0 Maven Repository
   • Application Platform 6.1.0 Maven Repository
   • Application Platform 6.0.1 Maven Repository
   • Application Platform 6.0.0 Maven Repository

   Unpack each of these files to a separate directory.

2. Modify the settings-zipped-repos.xml file located in the root directory of Red Hat JBoss Portal quickstarts:

   • For each zipped repository unpacked in the previous step, replace /path/to/repo/ within file:///path/to/repo/... with the fully qualified path of the directory where you unpacked the given zipped Maven repository in the previous step.

   • Note that path to each repository needs tobe set twice: one within <repository> tag and one within <pluginRepository> tag.

   • Be sure to use 3 forward slashes after file:. Two slashes are there for the protocol and one for the fully qualified path. For example:

       file:///home/joedoe/Quickstarts/jpp-6.2-quickstarts
     

3. Configure the Maven user settings.

   • Look for the settings.xml file in the ${user.home}/.m2/ directory. For example:

       For Linux or Mac: ~/.m2/settings.xml
       For Windows:       \Users\USER_NAME\.m2\settings.xml or \Documents and Settings\USER_NAME\.m2\settings.xml
     

   • If you have an existing settings.xml file, modify it with the configuration information from the example-settings.xml file.

   • If there is no settings.xml file, copy the modified example-settings.xml file to the .m2 directory for your operating system and rename it to settings.xml.

Start the Portal

1. Open a command line and navigate to the root of the JBoss server directory.

2. The following shows the command line to start the server with the web profile:

    For Linux:   JBOSS_HOME/bin/standalone.sh
    For Windows: JBOSS_HOME\bin\standalone.bat
   

Build and Deploy the Quickstart

1. Make sure you have started the Portal as described above.

2. Open a command line and navigate to the root directory of this quickstart.

3. Type this command to build and deploy the archive:

    mvn clean package jboss-as:deploy
   

   To deploy to other than default localhost:9999 JBoss instance, copy the following configuration just after <artifactId>jboss-as-maven-plugin</artifactId> in the pom.xml file and adjust it to suit your needs. username and password elements can be omitted sometimes, depending on your JBoss security settings.

    <configuration>
        <hostname>127.0.0.1</hostname>
        <port>9999</port>
        <username>admin</username>
        <password>secret</password>
    </configuration>
   

   This will deploy target/cdi-scopes-portlet.war to the running instance of the portal.

Access the deployed Portlet

To ensure that the example portlet has been deployed successfully, do the following:

• Point your web browser at the base URL of your portal (URL of a default local Red Hat JBoss Portal installation is http://127.0.0.1:8080/portal/classic).
• Sign in as root or other user with manager:/platform/administrators permissions.
• Go to Top Menu > Group > Administration > Application Registry and hit Import Applications. After that, you should see the newly imported Portlet Using Portet-Specific CDI Scopes under the Quickstarts Category.
• Then you can add the example portlet to a page of your choice: either (a) to a new page or (b) to an existing page.
  • If you have chosen (a) to add the portlet to a new page:
    • Go to Top Menu > Group Editor > Add New Page
    • In the Page Creation Wizard, fill in:
      • Node Name: cdi-scopes-portlet
      • Display Name: Portlet Using Portet-Specific CDI Scopes
    • Click Next
    • Leave Empty Layout as it is and hit Next
    • Drag-and-Drop Portlet Using Portet-Specific CDI Scopes from the Page Editor dialog to the middle of the Page Creation Wizard
    • Click the Diskette-like Finish button in the header of the Page Editor dialog and see the newly added portlet in action.
  • If you have chosen (b) to add the portlet to an existing page:
    • Navigate to the page where you want to add the portlet and go to Top Menu > Group Editor > Edit Page
    • Drag-and-Drop Portlet Using Portet-Specific CDI Scopes from the Page Editor dialog to a place of your choice within the page.
    • Click the Diskette-like Finish button in the header of the Page Editor dialog and see the newly added portlet in action.

Undeploy the Archive

1. Make sure you have started the JBoss Server as described above.

2. Open a command line and navigate to the root directory of this quickstart.

3. When you are finished testing, type this command to undeploy the archive:

    mvn jboss-as:undeploy
   

Use JBoss Developer Studio or Eclipse with JBoss Tools to Run this Quickstart

You can also deploy the quickstarts from Eclipse using JBoss Tools. For more information on how to set up Maven and JBoss Tools, refer to the JBoss Enterprise Application Platform 6 Development Guide or Get Started Developing Applications.

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
