David J.,
I was looking for implementing WorkManager API (JSR-237) using
current geronimo ThreadPool infrastructure . I think current version
of geronimo allow to define only one ThreadPool gbean per JVM
(Because GBEAN_INF is public static final). Which is fine, Just
wanted to make sure that i am interpreting it right?
No quite - the GBeanMetadata in GBEAN_INFO describes a class of GBean
not a specific instance. Just as in plain Java there can be multiple
instances of any GBean; the (persistent) instance data is stored in
GBeanData objects.
In this case we
have to define WorkManager as new gbean and implement it to manage
its own thread pool, Geronimo admin would have capability to
configure multiple WorkManager gbean.
I think there is a good case for a central work manager that can be used
by anything seeking to have work done - not only the J2CA Connectors but
also the EJB and web invokers, timers.
It may be appropriate do this using the raw JSR-237 API, or we may want
to have an internal SPI and then have the 237 implementation bridge to it.
