Building Your First Plugin
Now that XperienCentral is installed, it’s time to build your first plugin. The first plugin will contain one component: the helloWorld element component. After building and deploying this plugin, there will be a new element in XperienCentral. If that element is placed on a page, the text “Hello World!” will be displayed on the web page.
Maven
XperienCentral requires Maven 3.3.x. It’s very easy to check which version you are currently using: open a command prompt and type:
mvn -versionTo download the latest version of Maven 3.3.x, go to the website: http://maven.apache.org/download.html.

Creating a Plugin with a Panel Component
After creating your first plugin with an element component, it’s time to create a new type of component: a panel. A panel is a pop-up in XperienCentral that usually contains functionality that performs maintenance on objects. An example of such a panel is the pop-up in which you can maintain web users in XperienCentral.

Creating a Plugin with a Media Item Component
In XperienCentral, the Content Repository can be filled with articles and multimedia items. These objects have a predefined set of metadata. If you need additional metadata for specific types of objects in the Content Repository, a new media item can be created. For example, vacancies have an additional selection list of predefined locations in the metadata.

In XperienCentral, the terms "media item" and "content item" are synonymous. For reasons of backward compatability with earlier versions of GX WebManager 9.x, these terms are used interchangeably throughout our documentation. |

Creating a Plugin with a Page Metadata Component
In XperienCentral, pages are the building blocks of your website. Pages have some default metadata properties like title, navigation title, publication date and so forth. The page metadata component allows the plugin programmer to add additional metadata fields to each page in XperienCentral. This part describes how to create a plugin based on the pagemetadata archetype.

Creating a Plugin with a Presentation Component
Each XperienCentral page is connected to a presentation (appearance). A presentation is connected to its own JSP template, used by XperienCentral to generate the HTML of the page. With this component it is possible to create new presentation. Presentations can have small differences (like another lead color or logo) or can be completely different.

Creating a Plugin with a Service Component
A service component is a so-called headless service - It has no user interface. Examples of services are mailing services, newsfeed imports, storage services and scheduling services. Often a service is used as support for components that work together, like a bookstore panel and a bookstore element: they depend on a service that regulates the storage of the content of the business objects.

Init parameter: ‘key’ = ‘value’
Creating a Plugin with a Sidebar Widget
You can add new sidebar (DOJO) widgets to XperienCentral.

Troubleshooting
The Plugin Does not Compile
Sun Microsystems provides two versions of Java for download on http://java.sun.com/:
- The Java Runtime Environment (JRE)
- The Java Development Kit (JDK)
The JDK consists of the JRE plus added extras. For plugin development you will need the JDK. If you get a build failure, check the following:
- Open the menu Window > Preferences > Java > Installed JREs.
- Ensure that a JDK version of Java is used in your JRE definition
- If the used JRE definition points to a JRE version of Java, then remove the reference to the JRE and create a new reference to the JDK.
