4 years ago Unfortunately docker requires periodic cleaning and full reset due to caching. I recommend running docker-compose down and docker system prune --volumes periodically.

4 years ago Thanks, yeah I realized solved it.
Side question: I notice in the example it will register the interface classes. How does cadence associate it with the actual implementation.
TripBookingWorkflow trip1 = workflowClient.newWorkflowStub(TripBookingWorkflow.class); try { trip1.bookTrip("trip1"); } catch (WorkflowException e) { // Expected e.printStackTrace(); }
Say if there are multiple implementation of the trip booking workflow class. How does it know what implementation it’s using.
Thanks Derek

4 years ago When trip1.bookTrip is called it is converted by the Java client to StartWorkflowExecution gRPC call. One of the parameters of the call is TaskList which is the name of a queue activity tasks are dispatched through. Activity worker listens a task list for activity tasks and then dispatches them to the implementation object registered with the worker. Only one implementation of the activity interface per task list is allowed. So if you need more than one implementation then you have to use different task lists to dispatch tasks to them.
Use ActivityOptions.TaskList property when creating an activity stub to override the task list name.
I recommend joining Cadence Slack Workspace to continue the conversation.

4 years ago I will close this ticket since Max helped you resolved it. Hopefully you get answers to your other questions @darewreck54, if not, it's a good idea to join the cadence slack channel for future discussion.
I'm trying to run the example setup of cadence, I'm running into a lot of issues. I can't even bring up the front end at localhost: http://localhost:8088/
When I run the next command in the instructions:
When i try to start up the front end UI http://localhost:8088/, I get the following error in cadence.
Is there any other special configuration I need on my computer?
Any help appreciated, Thanks! Derek
