There are many tasks involved in creating and maintaining message flows:
The workbench provides a set of toolbar icons that invoke wizards that you can use to create any of the resources associated with message flows, for example, message flow projects and ESQL files. Hover your mouse pointer over each icon to see its function.
The workbench lets you open resource files with other editors. Use only the workbench message flow editor to work with message flow files, because this editor correctly validates all changes that you make to these files when you save the message flow.
When you have completed developing your message flow, deploy it to a broker to start its execution.
