[Building Sakai] Register a new HelpHandler to override the existing default one.

[Mihai Rus]

Hello Members of Sakai Dev List,

At LOI we want to override the default HelpHandler in the portal with the handler of Knowledgebase, an open source tool developed by EDIA.

The help link in Sakai, that appears in any newly created site by default, is implemented with handlers. Both the HelpHandler (default help handler) and the EdiaKnowledgebaseHandler are registered on  SkinnableCharonPortal with the same URL fragment: "help". The order in which the handlers are loaded is random, so we have Edia knowledgebase sometimes and the default help tool every other time.

We need the Edia Knowledgebase every time. We do not want to enforce a deploy order on the war-s when they are deployed in the server, so that leaves us with 2 solutions:


1.       Keep both handlers, but enforce from code that EdiaKnowledgebaseHandler is the one that is active. Can I set some kind of priority on a PortalHandler, to override all other PortalHandler-s that have the same URL fragment, and are registered in random order on the same Portal?

2.       Delete the default HelpHandler and have just the EdiaKnowledgebaseHandler. If I do this, will Sakai work the same with regards to putting the help link on any newly created site?

If someone can give answers to any of the two questions, it will be appreciated.
