Thanks Marshall for the information and for asking :) What I have tried is that I have a description of an aggregate analysis engine which has 4 primitive analysis engine defined. Those primitive AE descriptions are all fully defined (no imports) under the "delegateAnalysisEngine/analysisEngineDescription" tag. I do this because those primitive AE descriptions are generated on the fly. For one thing, each primitive AE has its own PEAR-compliant directory. In this case, I could not figure out how to tell UIMA the location those directories.
Excerpt from section 5.8 in the UIMA References page: "As of version 2.2, the framework supports component descriptors which are PEAR descriptors. These descriptors define components plus include information on the class path needed to run them." Question: To get the individual class loader for each primitive AE defined in an aggregate AE, do we have to specify/map the PEAR descriptor (<componentID>_pear.xml?) for each of every primitive AE? If so, where and how to do it? Any comments/recommendations would be appreciated.
