Hello everyone, How to access input/output parameters set in ServiceTask in Camunda-Modeler using Java?. Is it just using execution.getVariable(variableName); Best Regards, Raghu

[image] rpalakodety: Is it just using execution.getVariable(variableName); That should work - but filling in the input/output parameters isn’t a requirement, you can get any variable this way provided that it was set into the contenxt

Hi Niall, Thank you for responding. I dont see anything in the logs. I set the input parameter “oid” to a string value as shown in the picture below [pic1] and my code is public class ServiceTask implements JavaDelegate{ @Override public void execute(DelegateExecution execution) throws Excep…

Raghu, try this: @Service("Logger") public class LoggerDelegate implements JavaDelegate { final Logger LOG = LoggerFactory.getLogger(LoggerDelegate.class); public void execute(DelegateExecution execution) throws Exception { LOG.info("\n\n ... LoggerDelegate invoked by " …

Hey Rob, Thank you for the reply. Unfortunately, it is the same, I dont see anything in the logs. Is there anything else I could do?. Best Regards, Raghu

That would be: execution.getProcessInstanceId() If you set a process variable “oid” of type String before then the code execution.getVariables()…

[image] rob2universe: Raghu, where do you expect this oid variable to come from? I set the inputParameter “oid” for the ServiceTask in the modeler to a random value. And I am not trying to get processInstanceId. I am trying to access the value set for the variable “oid” in my code snippet pos…

Raghu, hard to tell what your issue is without the process model, but here is a working example. It a) maps a static string “oid” into a script task and prints it b) maps a static string “oid” into a service task (delegate expression to Spring bean), which prints it rob2universe/process-m…

Are you able to check the values in the cockpit? http://localhost:8080/camunda/app/cockpit/default/#/dashboard Either for x or oid for the process Instance?

@rpalakodety were you able to resolve this issue? I am trying to access input/output variables during task creation to emit events from listener looks like it is not accessible. Input variables are accessible only post assignment and output variables are accessible post task completion. It makes s…
