You might take a look at the uimaFIT (http://uimafit.googlecode.com) AggregateBuilder class: http://code.google.com/p/uimafit/source/browse/trunk/uimaFIT/src/main/java/org/uimafit/factory/AggregateBuilder.java See the unit test for an example: http://code.google.com/p/uimafit/source/browse/trunk/uimaFIT/src/test/java/org/uimafit/factory/AggregateBuilderTest.java Hope this helps!
