Write modules

Define global or theme-specific contributions containing a theme module, which applies to different scopes through theme profiles. Modules define contributions using a plugin.xml or JSON file.

System modules

Defined in a plugin.xml file as part of a compressed file in the portal class path, web module, or as a single file in the WEB-INF directory of a web module to make the modules available to all themes in the system. Declare the theme module within its extension point:

com.ibm.portal.resourceaggregator.module

Theme-specific modules

Defined in a JSON file within its contributions folder. Location can be changed by setting profile metadata...

resourceaggregation.contributions.folder

These files are automatically scanned by the system, and the defined contributions are registered for the theme.

XML schema

plugin.xml example

The following code is an example of a plugin.xml file where the module is deployed within a web application with the context root...

res:{war:context-root}/

<extension point="com.ibm.portal.resourceaggregator.module" 
           id="testModuleExtension1">

JSON file example

The following code is a JSON file example...

THEME_ROOT/contributions/myModules.json file

Keys that allow for multiple child entries on the same level are used in the plural form. For example, prereq becomes prereqs and capability becomes capabilities. File paths must start with a forward slash and are resolved relative to the theme root folder. JSP files cannot be served out of WebDAV. All resources relative to the theme root must be of a static type, for example, js, CSS, or HTML.

Contribution URIs for Web Modules

{war:context-root}

This variable fetches the context root of the containing WAR file and inserts it in place. It only works for modules defined as part of a WAR file. This does not work for modules defined in WebDAV or somewhere else in the classloading hierarchy, for example, a shared application.
