[lsp4j-dev] question about adding services

[Scott Lewis <slewis@xxxxxxxxxxxxx>]

Howdy,

I'm looking at using lsp4j to implement an OSGi Remote Services 
distribution provider.   Remote Services is an OSGi specification for 
exposing local services to external processes with standardized endpoint 
meta-data [1, 1a].    ECF has support for pluggable distribution 
providers...that are responsible for object ser/deserialization and 
communications transport [2].  It should be reasonably simple to use 
lsp4j/json-rpc to implement a new distribution provider that exposes 
OSGi services to remotes using JSONRequests, json-rpc for serialization 
and transport etc.

I've only just started inspecting/trying to understand lsp4j and have a 
questions

1) OSGi services are dynamic...i.e. they can be added/removed from the 
service registry at any time.   It appears to me that the current use 
cases of lsp4j are based upon the notion of a static Launcher/Builder, 
where the set of services is statically setup by the builder and then 
exported/made available upon create() and startListening().   Is that 
correct or am I misunderstanding something about how lsp4j currently works?

2) It seems like it would be possible to create a new Launcher/Builder, 
and some additional set of services and impls that would support the 
dynamic registration and unregistration of LSP service interfaces.   
Does that seem like the right way to go or would there be another way?

Thanksinadvance for comments or pointers.

Scott
