How to add the process variable in process instance ? Example ?

[frederikherema1]

There are various ways of adding variables. Eg, when starting a process:


Map<String, Object> vars = new HashMap<String, Object>();
vars.put("variableToSet", 123);

ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("processKey", vars);

On a running process-instance:


runtimeService.setVariable(processInstance.getId(),"varToSet", 456);

Look at the runtimeServcie API for more methods related to variables. Read all javadocs of the API-classes to get a good overview of what is possible…
