Hi Eli,
Based on the sample code, I presume you are using uimaFIT to wire up the
InputStreamCollectionReader probably came from cleartk-utils. Where it came
from is probably not so important though...
CollectionReaders were designed to read in a collection of documents/batch
processing (hence the examples have Files In a Directory example).
If you are really looking to have dynamic text in some sort of real-time or
SOA architecture, then you may want to take a look at creating the jCAS and
setting the text on it? uimaFIT also has a good example of this [2].
Something like:

If it's batch processing, you may find Tim's bagofcui's example [1] helpful
based on your example...


Hope that helps...
