I'll show you how you can add and read custom variables in
WorkflowServiceImpl.startWorkflow() method.
Create a new QName and add this into properties parameter
collection.
WorkflowserviceImpl.startWorkflow(....)
{
............
QName
customVariable = QName.createQName("MyCustomVariable");
parameters.put(customVariable, "MyCustomVariableValue");
}
Reading the custom workflow variable during updateTask ()
method.
workflowServiceImpl.updateTask(...)
{
......
WorkflowInstance
workflowInstance = workflowTask.getPath().getInstance();
String workflowId =workflowInstance.getId();
int colonIndex = workflowId.indexOf("$");
String executionId
= workflowId.substring(colonIndex+1);
String MyCustomVariableValue=(String)
getRuntimeService().getVariable(executionId, "MyCustomVariable");
}
Add the below private method to get activitiRuntimeService bean from bean
factory.
private
RuntimeService getRuntimeService()
{
if (this.activitiRuntimeService
== null)
{
this.activitiRuntimeService
= beanFactory.getBean("activitiRuntimeService",
RuntimeService.class);
}
return this.activitiRuntimeService;
}
Activiti Runtime service is used to get the custom
workflow variable from a workflow instance.
