Communication with persistent wires | HCL Digital Experience
You can use portlet wires for communication between portlets. Portlet wires are persistent data links.
- Portlet events
- This supports JSR 286 portlets only. The Java Portlet Specification 2.0 defines a model for communication by publishing and subscribing based on portlet events. This model is supported in HCL Portal Version 8.5. Portlet events can have complex objects as payload, if they provide an XML binding. With portlet events, HCL Portal Version 8.5 also supports communication links between remote (WSRP V2.0) portlets.
- Cooperative portlets
-
Only JSR 286 portlets support this communication technique. HCL Portal Version 8.5 still supports the HCL specific cooperative portlet programming API that was provided by previous releases and is known as the Property Broker. However, if you develop new portlets, use the portlet events based on the JSR 286 standard instead. It provides equivalent and compatible functionality. For more information about moving from cooperative portlets to JSR 286 events, refer to Interoperability between events and cooperative portlets.
