Whether or not a web browser can be a client for this service depends 
upon what provider/transport is being used.  For example, if you 
implemented the ECF REST service as an http servlet then you could do as 
you say...i.e. just invoke from a web browser.  Given you have the URL 
listed as http://localhost:3797/server1 it seems you may be able to do 
this right now (i.e. http).  Clearly this is because the browser 
understands and can make http requests, and not other types of requests 
(unless something is else is added to the browser, of course).

But if you are using some other provider/protocol for exposing the web 
service (e.g. ecftcp, JMS, etc), then the browser may not know of the 
protocol, and so won't be able to use it directly.

One enhancement that several ECF committers have discussed previously is 
the addition of server-side classes to expose any ECF remote service as 
a web-based service...i.e. to URL path value and/or parameters and match 
them to ECF remote service lookups, and actual service calls.  But these 
classes have not been added yet.
