[jboss-dev-forums] [Design of JCA on JBoss] - Re: JCA antipattern? Or not?

It's my understanding that JCA does not cache jms consumers so every call to createConsumer() in the above is going to result in a new consumer being created on the jms provider.

But I doubt it would work in practice. e.g. if the consumer is configured for read ahead there would be messages sitting in limbo until somebody reuses the JCA connection and "recreates" the same consumer.
