Is there a specific reason to use PEARs?
As far as I remember (but I could be wrong, it's been a few years), the
main advantages of using them (automatic class path configuration, some
degree of isolation between components) was lost when we wanted to change
configuration parameters because then we would need to use the AE
descriptor instead of the PEAR descriptor (at least with CPE). If you're
not going to use the PEAR descriptor then an installed PEAR is not much
more than a bunch of JARs, and component descriptors with tons of
hard-coded absolute file paths, so you should be able to just use and
configure a component based on those descriptors (without anything
PEAR-specific).
We have since switched to doing everything with uimaFIT which gives you
many many possibilities to adapt your workflow, configure engines
programatically, etc. For us the change has been hugely positive, both for
development (and debugging) and for deployment in a wide variety of ways
and environments.
Best,
Jens
