## Running the jsonbbasics Example Application

This section describes how to build and run the `jsonbbasics` example application. This example is a web application that demonstrates how to serialize an object to JSON and how to deserialize JSON to an object.

The `jsonbbasics` example application is in the `tut-install/examples/web/jsonb/jsonbbasics` directory.

The following topics are addressed here:

- Components of the jsonbbasics Example Application

- Running the jsonbbasics Example Application

### Components of the jsonbbasics Example Application

The `jsonbbasics` example application contains the following files.

- Two JavaServer Faces pages.

  - The `index.xhtml` page contains a form to collect data that is used to create a `Person` object.

  - The `jsongenerated.xhtml` page contains a text area that displays the data in JSON format.

- The `jsonbBean.java` managed bean, which is a session-scoped managed bean that stores the data from the form and directs the navigation between the Facelets pages. This file contains code that uses the JSON Binding API.

### Running the jsonbbasics Example Application

This section describes how to run the `jsonbbasics` example application from the command line using Maven.

To run the jsonbbasics example application using Maven:

1. Make sure that GlassFish Server has been started (see Starting and Stopping GlassFish Server).

2. In a terminal window, go to:

       tut-install/examples/web/jsonb/jsonbbasics

3. Enter the following command to deploy the application:

       mvn install

4. Open a web browser window and enter the following address:

       http://localhost:8080/jsonbbasics/

5. Enter data on form and click Serialize to JSON to submit the form. The following page shows the JSON format of the object data.

6. Click Deserialize JSON. The index page displays and contains the fields populated from the object data.
