|Re: [higgins-dev] java.security style IdAS Registration|
I've been wondering about the way the current IdASRegistry works and am interested in finding out what you'll be doing to change it. For example, I dislike that the current IdASRegistry gets populated with Context Factories that may never be used. Sometimes I'm left wondering -- why do we need an IdASRegistry at all?
I think we need some use cases. If the only use case we have is like this:
U1) From a known ContextID, create an instance of IContext
then it seems like we only need a way to resolve the contextID to the proper config data, from that context config we locate the context factory config data, and between these two sets of data, we're able to get an instance of the factory, and from that, get an instance of the context. For this, I don't see a need to fill up a registry from which we then query as to which factory can produce the context.
If we have other use cases like:
U2) Enumerate all known Context Factories
U3) Enumerate all known Contexts, all instantiated Contexts, or all potential Contexts
then we might need something more like today's registry. At first, we thought we might need U2 and/or U3, but no one has ever used them (that I know of).
Likely there are even more use cases that I haven't listed, but none of which have been required yet either.

Just to let everyone know, I have been working on a replacement for IdASRegistry, which uses XRDS documents to register and retrieve context factories. I will have much more information about this within the next few days and then hope to get feedback / suggestions on it!
For now I can say it will make proper use of the Configuration component, so if you make JNDIContextFactory a configurable component, that's the way to go!

Is anyone using the java.security style of registering Context Factories any more? It seemed an odd fit from the get go but now that I'm converting over to the new higgins configuration code in the JNDI CP, I will not even be able to support that method any more. I'm making the JNDIContextFactory a configurable component and the java.security method doesn't allow for any additional configuration to be passed. I could support a "null" configuration for the JNDIContextFactory (which is, in essence, what I've done until now), but I figure, why support this method at all any more if noone is using it. The only code I know of which even try to test it is in the JNDI CP test suite.
