Learn how the pieces of a Temporal application work together. Follow the Run your first app tutorial to learn more about Temporal Workflows.

Note: This project uses Snipsync comment wrappers to automatically keep code snippets up to date within our documentation.

If you don't already have the temporal CLI installed on your machine, follow the Install the Temporal CLI instructions before you continue with the next step.

Open a terminal window and run the following command to start the Temporal Service using the temporal CLI:

temporal server start-dev --ui-port 8080 --db-filename=temporal.db

The second argument specifies the port number for the Temporal Web UI to use. If you have something else running on port 8080, modify this command to specify a different port number.

Open another terminal window and run the following command to run the Worker:

mvn compile exec:java -Dexec.mainClass="moneytransferapp.MoneyTransferWorker" 

Open another terminal window and run the following command to start the Workflow:

mvn compile exec:java -Dexec.mainClass="moneytransferapp.TransferApp"

The Workflow Execution should quickly complete. You can view its status and details with the Temporal Web UI, which you can access at http://localhost:8080.

This project contains a Makefile, which defines targets corresponding to the mvn commands shown in the above examples. If you have the make utility installed on your machine, you can run make worker and make run as an alternative to running the commands in steps 2 and 3.
