Asynchronous Java

From: "andrew cooke" <andrew@...>

Date: Wed, 31 Jan 2007 09:42:02 -0300 (CLST)

I've released POrqi 1.0 - it converts Java code to run "asycnhronously". 
In other words, it instruments selected POJO classes with proxies to build
"services" so that threads remain within each service.  So the calling
between services is asynchronous - the result of the call is returned via
a separate call back from callee to caller.

This may seem crazy, but it will make is easier to generate reliable
distributed systems from POJOs.

What surprises/pleases me most is that this can be done (1) without
changing the POJOs and (2) with pure Java.

POrqi 1.2 (Refactored, Spring)

From: "andrew cooke" <andrew@...>

Date: Thu, 8 Feb 2007 23:47:32 -0300 (CLST)

Actually POrqi 1.1 has Spring support, but it was never formally announced.

POrqi 1.2 is now here - http://www.acooke.org/jara/porqi/html/wiki.html -
and is a major refactoring of the core functionality.  There's now a
single proxy that calls on a set of cooperating delegates to do the hard
work.  The wiki (link above) includes updated technical details.

The motivations were: (1) to clean up the code now that basic unit tests
of the entire system are possible; (2) to reduce the clutter in the proxy
itself (which now adds a single method to the POJO); (3) to allow
different delegates to be used in the future (particularly, to add support
for queues / reliable messaging).

Next I should probably look at continuations.

Andrew
