Entries, ServiceTemplates, and JavaSpaces

We have an application that used to make direct RMI calls from a
client to a service. Now we'd like to instead distribute our work
using JavaSpaces. Previously we were using a ServiceTemplate to find
appropriate agents and agents were registering their capabilities with
a user-configurable set of properties (from a properties file) that
were turned into entries.

With JavaSpaces it seems we lose the ability to register for
notification via a ServiceTemplate, and instead must offer a single
Entry instance with a pre-defined set of fields. First question then:
does my grasp of the situation seem correct? Second: Is there no way
at runtime to configure an Entry with dynamic properties?

Alternatively the agents can register for notification of a generic
Entry's appearance at which point they can check a Map on the Entry
for matching criteria. I'm sure this has been done? Sounds like a bit
of a pain, though, to implement one's own matching criteria--is there
something already written to do this and is this the recommended way
to do what we're trying to do?

Thanks,

Jeff
