Classes:

ChainAction: An Action implementation that delegates to a configured Chain (or Command) for performing the actual business logic related to a request. The name of the chain to be executed is specified by setting the parameter attribute of the <action> element configuring this action. For example: <action path="/myaction" type="org.apache.struts.chain.legacy.ChainAction" name="myform" scope="request" input="/mypage.jsp" parameter="name-of-chain-to-execute" Prior to calling the specified chain (or command), this action sets up a Context object containing the relevant properties, along with the following ...
DispatchAction: An Action implementation that delegates to a Chain (or Command) that is specified by a request parameter whose name is configured in the parameter attribute of the <action> element configuring this action. For example: <action path="/myaction" type="org.apache.struts.chain.legacy.DispatchAction" name="myform" scope="request" input="/mypage.jsp" parameter="name-of-request-parameter" Prior to calling the specified chain (or command), this action sets up a Context object containing the relevant properties, along with the following additional attributes: mapping - The ActionMapping passed ...
TilesPreProcessor: Command class intended to perform responsibilities of the TilesRequestProcessor in Struts 1.1. Does not actually dispatch requests, but simply prepares the chain context for a later forward as appropriate. Should be added to a chain before something which would handle a conventional ForwardConfig. This class will never have any effect on the chain unless a TilesDefinitionFactory can be found; however it does not consider the absence of a definition factory to be a fatal error; the command simply returns false and lets the chain continue. To initialize the TilesDefinitionFactory , use org.apache.struts.chain.legacy.TilesPlugin ...
ComposableRequestProcessor: ComposableRequestProcessor uses the Chain Of Resposibility design pattern (as implemented by the commons-chain package in Jakarta Commons) to support external configuration of command chains to be used. It is configured via the following context initialization parameters: org.apache.struts.chain.CATALOG_NAME - Name of the Catalog in which we will look up the Command to be executed for each request. If not specified, the default value is struts . org.apache.struts.chain.COMMAND_NAME - Name of the Command which we will execute for each request, to be looked up in the specified Catalog . If not specified, ...
CatalogConfiguratorPlugIn: CatalogConfiguratorPlugIn parses the configuration resource specified by the path or resource property to configure the default org.apache.commons.chain.Catalog registered with the org.apache.commons.chain.CatalogFactory for this application. path - Context-relative path to a web application resource that contains chain definitions. resource - Absolute resource path to a class loader resource that should be in a JAR file under /WEB-INF/lib , or a separate file under /WEB-INF/classes .
TilesPlugin: Permissive version of TilesPlugin which doesn't mess with processor class. Completely extends TilesPlugIn except for overriding protected method initRequestProcessorClass(ModuleConfig) to a no-op. Note class name capitalization consistent with org.apache.struts.tiles.TilesPlugin rather than most other Struts plug-ins to avoid snagging folks who quickly edit their struts-config.
ValidateActionForm: Validate the properties of the form bean for this request. If there are any validation errors, execute the child commands in our chain; otherwise, proceed normally. Also, if any errors are found and the request is a multipart request, rollback the MultipartRequestHandler .
ExceptionCatcher: Intercept any exception thrown by a subsequent Command in this processing chain, and fire the configured exception handler chain after storing the exception that has occurred into the Context .
SelectInput: Validate the properties of the form bean for this request. If there are any validation errors, execute the child commands in our chain; otherwise, proceed normally.
AbstractAuthorizeAction: Determine whether the requested action is authorized for the current user. If not, abort chain processing and perferably, return an error message of some kind.
AbstractValidateActionForm: Validate the properties of the form bean for this request. If there are any validation errors, execute the specified command; otherwise, proceed normally.
AbstractSelectModule: Cache the ModuleConfig and MessageResources instances for the sub-application module to be used for processing this request.
SelectModule: Cache the ModuleConfig and MessageResources instances for the sub-application module to be used for processing this request.
PopulateActionForm: Populate the form bean (if any) for this request. Sets the multipart class from the action config in the request attributes.
RequestNoCache: Check to see if the controller is configured to prevent caching, and if so, set the no cache HTTP response headers.
AbstractExecuteAction: Invoke the appropriate Action for this request, and cache the returned ActionForward .
AbstractSelectInput: Select and cache a ForwardConfig that returns us to the input page for the current action, if any.
ExecuteAction: Invoke the appropriate Action for this request, and cache the returned ActionForward .
AbstractRequestNoCache: Check to see if the controller is configured to prevent caching, and if so, request no cache flags to be set.
SelectForward: Create and return a ForwardConfig representing the specified module-relative destination.
AbstractSelectAction: Cache the ActionConfig instance for the action to be used for processing this request.
SelectAction: Cache the ActionConfig instance for the action to be used for processing this request.
AbstractSelectForward: Select and cache the ActionForward for this ActionConfig if specified.
AbstractExceptionHandler: Invoke the local or global exception handler configured for the exception class that occurred.
AbstractPerformForward: Perform forwarding or redirection based on the specified ForwardConfig (if any).
