Contexts and Dependency Injection (CDI) Sample

The CDI sample contains a server definition which includes the CDI and JSP features. It also contains a very simple CDI application, cdiApp.war, which contains a single JSP, sample.jsp. This JSP looks up a request-scoped bean that is also injected with another request-scoped bean. The JSP prints a message indicate whether or not the beans were correctly injected by the container.

This sample can be installed onto runtime versions and later.

Installation Instructions

Online installation (requires or later):

  1. Install the sample by running the command below from the bin directory of your server installation:
    installUtility install cdiSample

Any missing features required by the server will be installed for you.

Offline installation:

  1. Download the cdiSample.jar using the download button at the top of the page and place it in the root of your server installation.
  2. Extract the sample into the Liberty installation by running the command below from the root of your server installation:
    java -jar cdiSample.jar

Any missing features required by the server will need to be installed separately.

Running The Application

To run the cdiApp application:

  1. Start the cdiSample server by running the command below from the bin directory in the Liberty profile installation:
    server run cdiSample
  2. Confirm the application started by looking for the following message in the log:
    CWWKZ0001I: Application cdiApp started in XX.XX seconds.
  3. In your browser, enter the URL for the application: http://localhost:9100/cdiApp/sample.jsp (where port 9100 assumes the httpEndpoint provided in the sample server.xml has not been modified):
  4. In your browser, you should see the message
    Congratulations! You successfully used CDI to inject a bean at the request scope!


The cdiApp.war file contains the source and binaries for the application, and can be used to import it to Eclipse.
