Its all in the RequestProcessor http://cvs.apache.org/viewcvs.cgi/jakarta-struts/src/share/org/apache/struts/action/RequestProcessor.java
The main process(request, response) method in RequestProcessor calls processMapping(request, response, path) which calls findActionConfig(path) in ModuleConfig to find the Action mapping that you configured in the struts-config.xml. Later on in the process() method it calls the processActionCreate() method to get hold of the Action instance and then processActionPerform() actually calls the action's execute() method.
