I created this java filter function extension, that inherits from com.hp.hpl.jena.sparql.function.FunctionBase1. I am able to call the function in a LET statement using the java URI scheme java:org.example.functions.myfunction, outside TBC, as long as my jar file is in the class path of the executing program. I also know that we can create functions extensions in TBC by writing a plug-in that uses the org.topbraid.sparql.functions extension point, and inherit from org.topbraid.sparql.functions.AbstractFunction1 (we tested this as well). My question are: 1. Isn't there an easier way of using my first jar where the function extension inherits from com.hp.hpl.jena.sparql.function.FunctionBase1 directly in TBC without writing a TBC plug-in (and calling that function using the java URI Scheme "java:org.myexample.functions.myfunction")? 2. Since TBC uses ARQ, adding my jar to the TBC classpath should be enough for it to work (tried this method but unsuccessful). Does TBC not recognize the java URI scheme that ARQ uses?
