timer

clocks how long the action (including nested interceptors and view) takes to execute

logger

logs the action being executed

chain

makes the previous action's properties available to the current action. Used to make action chaining (reference: Result Types)

static-params

sets the parameters defined in struts.xml onto the action. These are the <param /> tags that are direct children of the <action /> tag

params

sets the request (POST and GET) parameters onto the action class. We have seen an example of this in TODO

model-driven

if the action implements ModelDriven, pushes the getModel() result onto the Value Stack

component

enables and makes registered components available to the actions.

token

checks for valid token presence in action, prevents duplicate form submission

token-session

same as above, but storing the submitted data in session when handed an invalid token;

validation

performs validation using the validators defined in {Action}-validation.xml (reference: Validation).

workflow

calls the validate method in your action class. If action errors created then it returns the INPUT view. Good to use together with the validation interceptor (reference: Validation)

servlet-config

give access to HttpServletRequest and HttpServletResponse (think twice before using this since this ties you to the Servlet API)

prepare

allows you to programmatic access to your Action class before the parameters are set on it.

conversionError

Adds field errors if any type-conversion errors occurred\

execAndWait

Spawns a separate thread to execute the action

fileUpload

Sets uploaded files as action files (File objects)
