Note: Since Struts2 version 2.3.15.3 if you are using <s:submit> tags with action attribute you need to enable support for action: prefix.

Put that in your struts.xml file:

Showing action flow steps in JSP

...

Implement ActionFlowStepsAware interface in action and create getter for ActionFlowStepsData:

...

...

In JSP iterate over ActionFlowStepsData#steps map. Use #key and #value to get step index (starting from 1) and action name. The ActionFlowStepsData#stepIndex property holds index of current step.

Available from struts2-actionflow-plugin 2.3.0

As a result of that you can skip actions based on user input and current action name.
