Design pattern for 1 Producer/multiple Consumers?

[Paul Tomblin]

I'm doing a simple Producer/Consumer thing based on the example in the Sun
docs, where the Consumer does a wait until there is something to consume,
then it consumes it and does a notify, and the Producer does a wait until
there is nothing to consume and then adds it and does a notify. But now I
need a bunch of Consumers. Is there a standard design pattern for this,
or am I going to have to figure it out myself?

This is a standard JavaSpaces' Master-Worker pattern. See
http://www.jini.org for general information on JavaSpaces and just
Google "javaspaces master worker" for numerous examples.

pay special attention to the code example.

I knew there was a reason why I liked Java 1.5.

Thanks.

There are several idioms. /Java Concurrency in Practice/ by Brian Goetz, et
al., discusses a few of them.
