Re: [equinox-dev] Possible to use custom threadpool

[Thomas Watson <tjwatson@xxxxxxxxxx>]

Hi Olaf,

Currently Equinox spawns its own Threads to perform asynchronous event delivery and perform asynchronous operations (such as PackageAdmin and StartLevel operations). There is no way to plugin an external threadpool for Equinox to use.

OSGi is considering a specification on how Framework implementations should operate when they are embedded in an existing environment. I opened a bug against OSGi to investigate if an external thread pool should be able to be specified when embedding an OSGi Framework.

Hello,

we are investigating the possibility to use Equinox as some kind of high-end
plugin container for a massive legacy J2EE app. Therefore, we are tasked
with embedding Equinox into our J2EE application server, i.e. BEA WLS 9.2.
Preliminary discussion with our operating team have revealed that an
embedded OSGi container must not spawn its own threads but rather use those
provided and managed by the WLS. This requirement is not to be relaxed,
period ;-)

This begs the question whether it is possible to tell Equinox to use an
external threadpool. I this possible out of the box, or what would be the
steps involved to make it possible?

Regards,
Olaf
