[rules-dev] Loading xls decisiontable in KnowledgeBuilder

[Tihomir Surdilovic]

_The call builder.add never returns and doesn't throw an exception 
either, it simply vanishes without any explanation._

Highly unlikely. You are probably getting a NPE in ExcelParser or a 
FileNotFoundException but maybe not seeing the exception?
Also don't see where you build the KnowledgeBase in your pasted code. If 
you can create a self-contained test that reproduces the error, please post.

Also these types of questions are for the rules-users list.
