I don't use it, but the struts-menu add on may do what you want.
http://struts-menu.sourceforge.net/
Otherwise, the ModuleConfig class has a method findActionConfigs() which
returns an array of ActionConfig elements. In an Action you can get the
ModuleConfig from the ActionMapping. From ActionConfig you can get the path
and the role names associated.
Something like:
ModuleConfig moduleConfig = mapping.getModuleConfig();
ActionConfig[] actionConfigs = moduleConfig.findActionConfigs();
for (int i = 0; i < actionConfigs .length; i++) {
String path = actionConfigs[i].getPath();
String[] roleNames = actionsConfigs[i].getRoleNames();
boolean accessAllowed = false;
for (int j = 0; j < roleNames.length; j++) {
if (request.isUserInRole(roleNames[j])
accessAllowed = true;
}
}
