To develop a custom subscription we need to complete the following tasks Write a content adapter for the new content source Deploy the new content adapter Write a subscription portlet for the new content source Write a custom trigger handler Deploy the new subscription portlet OT EON Developers can create new subscriptions in order to utilize other types of content sources In order to develop a subscription a developer must create a subscription portlet a trigger handler and a content adapter The subscription application allows the subscriber to subscribe to the content source and set subscription matching parameters The content adapter retrieves data from the content source transforms it and sends it to the Subscription Manager The content adapter APIs are designed to make it as simple as possible for a user to publish data from new content sources as they become available The content adapter APIs enable the developer to focus on writing code to retrieve data from the content source rather than writing code to interface with the Subscription Manager Trigger handlers are also considered part of the subscription because they control what happens when an action is performed on a subscription such as on add on update on query or when a subscription matches content that is published to the system Write the content adapter The code java files for the following content adapters are packaged in the ear files found
