Use WebSphere Commerce services in portlets
There are two ways to use WebSphere Commerce services from a WebSphere Commerce portlet:
- Call a WebSphere Commerce service using the MVC portlet configuration file
Use the MVC portlet configuration file, portlet-config.xml, to call a WebSphere Commerce service without writing any additional code.
- MVC portlet configuration file syntax
The portlet-config.xml file contains action tags, render tags, and plug-in tags.
