Matthias,
that's what external resources are for. You declare them
in a descriptor, and they get loaded once by the framework.
See
http://incubator.apache.org/uima/downloads/releaseDocs/2.2.2-incubating/docs/html/tutorials_and_users_guides/tutorials_and_users_guides.html#ugr.tug.aae.accessing_external_resource_files
A real life example of such an external resource is the
HMM model file of the sandbox Tagger. Check the HmmTagger.xml
descriptor, IModelResource.java and ModelResource.java.

Hello,
I have a question concerning the setting of an Object as a configuration
parameter for an AnalysisEngine:
We are processing a corpus with several threads of the same UIMA
pipeline. There is a very large Java object or "resource" that is used
by an AnalysisEngine of this pipeline. it's a Dictionary object that
needs between 4 and 12GB memory. We would like to create only one object
and use this in all pipelines, because of the memory footprint. I
thought it could be possible to create it once and then set it as a
configuration parameter for all the components. This does not work,
because an AnalysisEngine does not accept to set an Object as a
configuration parameter.
So I thought about two solutions yet:
1. we use this component not as a AnalysisEngine but as a POJO and set
the Object by a simple setter.
2. using JNDI and resolve the object by a name - but I have no
experience with JNDI, so I would like to have somebody's opinion about
this approach.
regards
Matthias
