Whit this new library's there is a lot of problem using HashTabele as one of the input parameters in client execution.
With old library's everything work fine, why is know such problem using different types of data. I try to do this: String username; Map keyVals; String sessId; Object[] params = new Object[]{username, keyVals, sessId}; rez = client.execute("Calculus.DoInter", params);
