Overview of Dictionary Lookup
...
This can be done using class org.apache.ctakes.dictionary.lookup.ae.FirstTokenPermLookupInitializerImpl as the lookupInitializer, and using class OrangeBookFilterConsumerImpl as the lookupConsumer, provided you have the RxNorm dictionary, and you configure the LookupDescriptorFile resource to use your RxNorm dictionary.

Dictionary entries need to have been tokenized the way the pipeline tokenizes the document text. For example, the lookup algorithm will not find a lookup hit if a dictionary entry is "ear, skin" but the document text contains the same text ("ear, skin") and the pipeline has tokenized that text as the three tokens "ear" "," "skin". To find a lookup hit for the three tokens, the dictionary entry should be tokenized, with a space before the comma: "ear , skin".

Editing dictionary lookup AE descriptors in Eclipse
The analysis engine descriptors for this annotator use elements of type configurableDataResourceSpecifier. These cannot be modified from the Parameters or Resources tabs of the Component Descriptor Editor (at least not in UIMA 2.2). To view these values or edit them, use the Sources tab or open the descriptor with a text editor.
...
To determine the LookupDescriptorFile for an analysis engine, open the analysis engine descriptor (e.g. DictionaryLookupannotator.xml) and note the URL for the LookupDescriptorFile resource (e.g. lookup/LookupDesc.xml).
...
To better understand the dictionary lookup annotator code you could start by reading the Javadoc API for the classes DictionaryLookupAnnotator.java and FirstTokenPermutationImpl.java.'
