I agree regarding SOAP and River needing to be easier to deploy and
use. I think the conventions Dennis is using with Rio, makes deployment
much cleaner and easier to understand. I'm doing what I can, but
deployment isn't my speciality, I think the changes Dennis proposes goes
a long way towards it and we also need to get the community more
involved in the River container work your doing too.
Not too sure how to get the community more engaged, I think it's a side
effect of a very specialised user base.
Regards,
Peter.

Hi Peter:
I applaud your enthusiasm. Having said that, I’m not sure what River brings
to the internet space that isn’t already well-served by the http infrastructure
and RESTful services. I kind of think that race has run. I also don’t foresee
much uptake for mobile-code approaches (even dynamically-generated code) in the
internet space. Java’s reputation for insecurity on the browser has killed
that idea.
In the data centre and cloud, however, I think River/Jini is a great
substitute for the XML/SOAP approach. I’ve talked to hundreds of people over
the past ten years who are implementing SOAP-based SOA. The vast majority of
them are using Java for all their development. Assuming we can simplify
deployment so that mere mortals can actually use it, it should be a no-brainer
that writing Java-based services with Java interfaces is simpler than writing
Java-based services with WSDL-based interfaces to get platform neutrality that
hardly ever gets used.
Plus, Jini’s inherent resilience, combined with JavaSpaces, should be an easy
sell for scalable-on-demand systems (e.g. Amazon EC2).
Cheers,
Greg.

Components:
DNS-SRV Discovery
UDT JERI Endpoints- Firewall traversal& superior WAN performance
TLS Encryption
Reflective Proxies - no code downloads
Lambda expressions (for services) - remote dynamic code generation (this is
big, don't download a codebase, the jvm generates code on demand)
Secure serialization - limit classes to java.lang, and Jini trusted subsets.
Size constraints on method invocation returns - anti dos measure
A new internet lookup service, reflective proxy, with lambda expression based
lookup.
There's not a great deal of work required to do this and it should make a huge
difference to our userbase, which at present appears limited.
Thoughts?
Peter.
