RE: JESS: Mixing facts from Java and Jess script
He does close it on the third line, but that is what the problem is. The way the rule is defined below, the mon template should contain slots for reading, tstamp and posLshift. However, based on the error, the mon template generated by the defclass call does not contain the posLshift slot. So the last close-parenthesis after the posLshift line needs to be placed after the tstamp slot (assuming tstamp is part of the mon template). This will associate the reading and tstamp slots with the mon template and the truth_val slot with the posLshift template.
