Luminus Channels in LifeRay

Submitted by Anonymous on Tue, 2007-04-03 12:30

I am trying to find out if Luminus Channels can be consumed in other Portals such as LifeRay. Has anyone heard of this being done, or has tried, or has any insight into whether or not it can be done?

I was looking at the product

I was looking at the product page, it looks cool, but I doubt it supports the iChannel framework. Also it did not say anythin about JSR168. Now I could be wrong about this, but I believe that in the new Luminis/uPortal, there is an iChannel Framework emulator that runs in a JSR168 Portlet that makes channels backward compatible. Now I'm likely wrong on this but its something to look into. If thats the case you may be able to run iChannel based channels on any portal supporting JSR168. *again just a theory...

This looked interesting in the LifeRay spec sheet: Parallel (Asynchronous) Portlet Rendering Engine

Thanks for the input

Thanks for the input. I was not at Summit this year, but last year I recall one of the presenters saying that since Luminis Channels are JSR-168 compliant, then "theoretically" they should be able to be consumed by LifeRay. I am curious about all this because we are currently evaluating Spring/Mule/LifeRay. We are looking for a solution which could consume our existing Services, Luminis Channels, and any other third party services we so desire.

Portlets and Channels

Submitted by mitchelr on Mon, 2010-05-03 12:28.

First, Channels are a uPortal construct that I believe predates the Portlet standard. They were the primary mechanism for uPortal and the Portlet standard was later implemented using a "Portlet Channel". The two interfaces are not directly compatible. For instance, a single instance of the Portlet interface represents the "definition" of a channel, where a single instance of the IChannnel interface represents a single instance of the portlet in a user's current session.

It might be possible to reverse what was done for uPortal/Luminis 4 and build a Portlet that calls the IChannel interface for it's implementation (although some of the subtle differences may make this difficult to impossible). This would allow uses of Channel implementations in Liferay/Luminis 5.0. As far as I know, Sungard has made no attempt to do this, nor are they talking about doing this. However, I only a couple of sessions on Luminis 5.0 at Summit, so I might have missed something.

Second, Liferay implements JSR-286, which is Portlets 2.0. That standard is backwards compatible with JSR-168 (Portlets 1.0) or enough so to run almost any portlet implemented to the earlier standard.
