[rules-users] how to update object modified by call to remote web service

We are at 5.2.0 Final We recently moved our rules server (written in-house) to its own Tomcat instance. Some of our existing rules call a service to modify facts. With the move of the rules server, these calls to the service no longer happen in the working memory of the rules server. The rule must now capture the return from the call to the remote service, in order to see the changes made by the remote service call. Within the rule, this change is working fine. The RHS was: applicationService.applyInstruction($step); as above, the $step fact would not be updated within the rule WM now that the service is called remotely. However, when I changed this to $step = applicationService.applyInstruction($step); then $step did have the changes(I am verifying this by writing debug info to the log). BUT, the object that was passed in to execute() on the knowledge session did NOT have the changes. I have tried several things to fix this. one was to update($step) but this failed with "Update error: handle not found for object," I assume because the fact handle changed in the object returned from the service call. I also tried some variations on retracting and inserting the step: retract($step); $step = applicationService.applyInstruction($step); insert($step); and also tried using a different variable name: retract($step); $step2 = applicationService.applyInstruction($step); insert($step2); update($step2); both these above did not get errors, but also did not cause the updated object to return from session.execute() call. To summarize: in a call to execute() on a stateless knowledge session, an object is passed in a rule fires that calls a remote service that modifies the object within the rule, we catch the changed object that is returned from the service call within the rule, the changes to the object ARE visible on the return from execute(), the changes are NOT visible thanks for your help... -- View this message in context: http://drools.46999.n3.nabble.com/how-to-update-object-modified-by-call-t...
