<form-property> | Child of form-bean

The "form-property" element describes a JavaBean property that can be used to configure an instance of a DynaActionForm or a subclass thereof. This element is only utilized when the "type" attribute of the enclosing "form-bean" element is [org.apache.struts.action.DynaActionForm] or a subclass of DynaActionForm. If a custom DynaActionForm subclass is used, then the "dynamic" attribute of the enclosing <form-bean> element must be set to "true". Since Struts 1.1.

name The name of the JavaBean property described by this element.

reset The flag that indicates when this property should be reset to its "initial" value when the form's "reset()" method is called. If this is set to "true", the property is always reset when "reset()" is called. This can also be set to one or more HTTP methods, such as GET or POST. In such a case, the property will be reset only when the HTTP method used for the request being processed is included in this attribute's value(s). Multiple HTTP methods can be specified by separating them with whitespace or commas.

size The number of array elements to create if the value of the "type" attribute specifies an array, but there is no value specified for the "initial" attribute.

<action> | Child of action-mappings

The "action" element describes an ActionMapping object that is to be used to process a request for a specific module-relative URI. The following attributes are defined:

attribute Name of the request-scope or session-scope attribute that is used to access our ActionForm bean, if it is other than the bean's specified "name". Optional if "name" is specified, else not valid.

cancellable Set to "true" if the Action can be cancelled. By default, when an Action is cancelled, validation is bypassed and the Action should not execute the business operation. If a request tries to cancel an Action when cancellable is not set, a "InvalidCancelException" is thrown. [false]

catalog The name of a commons-chain catalog in which to look up a command to be executed as part of servicing this request. Only meaningful if "command" is also specified.

className The fully qualified Java class name of the ActionMapping subclass to use for this action mapping object. Defaults to the type specified by the enclosing <action-mappings> element or to "org.apache.struts.action.ActionMapping" if not specified. ["org.apache.struts.action.ActionMapping"]

command The name of a commons-chain command which should be looked up and executed as part of servicing this request.

extends The path of the action mapping configuration that this will inherit configuration information from.

forward Module-relative path of the servlet or other resource that will process this request, instead of the Action class specified by "type". The path WILL NOT be processed through the "forwardPattern" attribute that is configured on the "controller" element for this module. Exactly one of "forward", "include", or "type" must be specified.

include Module-relative path of the servlet or other resource that will process this request, instead of the Action class specified by "type". The path WILL NOT be processed through the "forwardPattern" attribute that is configured on the "controller" element for this module. Exactly one of "forward", "include", or "type" must be specified.

input Module-relative path of the action or other resource to which control should be returned if a validation error is encountered. Valid only when "name" is specified. Required if "name" is specified and the input bean returns validation errors. Optional if "name" is specified and the input bean does not return validation errors.

name Name of the form bean, if any, that is associated with this action mapping.

parameter General-purpose configuration parameter that can be used to pass extra information to the Action object selected by this action mapping.

path The module-relative path of the submitted request, starting with a "/" character, and without the filename extension if extension mapping is used.

NOTE: Do *not* include a period in your path name, because it will look like a filename extension and cause your Action to not be located.

prefix Prefix used to match request parameter names to ActionForm property names, if any. Optional if "name" is specified, else not allowed.

roles Comma-delimited list of security role names that are allowed access to this ActionMapping object. Since Struts 1.1.

scope The context ("request" or "session") that is used to access our ActionForm bean, if any. Optional if "name" is specified, else not valid. [session]

suffix Suffix used to match request parameter names to ActionForm bean property names, if any. Optional if "name" is specified, else not valid.

type Fully qualified Java class name of the Action subclass [org.apache.struts.action.Action] that will process requests for this action mapping. Not valid if either the "forward" or "include" attribute is specified. Exactly one of "forward", "include", or "type" must be specified.

unknown Set to "true" if this object should be configured as the default action mapping for this module. If a request does not match another object, it will be passed to the ActionMapping object with unknown set to "true". Only one ActionMapping can be marked as "unknown" within a module. [false]

validate Set to "true" if the validate method of the ActionForm bean should be called prior to calling the Action object for this action mapping, or set to "false" if you do not want the validate method called. [true]

catalog Name of the catalog to use when processing requests for this module. [struts]

className Fully qualified Java class name of the ControllerConfig subclass for this controller object. If specified, the object must be a subclass of the default class. ["org.apache.struts.config.ControllerConfig"]

command Name of the command to execute to process a request. [servlet-standard]

contentType Default content type (and optional character encoding) to be set on each response. May be overridden by the Action, JSP, or other resource to which the request is forwarded. ["text/html"]

forwardPattern Replacement pattern defining how the "path" attribute of a <forward> element is mapped to a context-relative URL when it starts with a slash (and when the contextRelative property is false). This value may consist of any combination of the following: - "$M" - Replaced by the module prefix of this module - "$P" - Replaced by the "path" attribute of the selected "forward" element - "$$" - Causes a literal dollar sign to be rendered - "$x" - (Where "x" is any character not defined above) Silently swallowed, reserved for future use If not specified, the default forwardPattern is "$M$P", which is consistent with the previous behavior of forwards. Since Struts 1.1. ["$M$P"]

inputForward Set to "true" if you want the "input" attribute of <action> elements to be the name of a local or global ActionForward, which will then be used to calculate the ultimate URL. Set to "false" (the default) to treat the "input" parameter of <action> elements as a module-relative path to the resource to be used as the input form. Since Struts 1.1. [false]

locale Set to "true" if you want a Locale object stored in the user's session if not already present. [true]

maxFileSize The maximum size (in bytes) of a file to be accepted as a file upload. Can be expressed as a number followed by a "K", "M", or "G", which are interpreted to mean kilobytes, megabytes, or gigabytes, respectively. ["250M"]

memFileSize The maximum size (in bytes) of a file whose contents will be retained in memory after uploading. Files larger than this threshold will be written to some alternative storage medium, typically a hard disk. Can be expressed as a number followed by a "K", "M", or "G", which are interpreted to mean kilobytes, megabytes, or gigabytes, respectively. ["256K"]

multipartClass The fully qualified Java class name of the multipart request handler class to be used with this module. ["org.apache.struts.upload.CommonsMultipartRequestHandler"]

nocache Set to "true" if you want the controller to add HTTP headers for defeating caching to every response from this module. [false]

pagePattern Replacement pattern defining how the "page" attribute of custom tags using it is mapped to a context-relative URL of the corresponding resource. This value may consist of any combination of the following: - "$M" - Replaced by the module prefix of this module - "$P" - Replaced by the value of the "page" attribute - "$$" - Causes a literal dollar sign to be rendered - "$x" - (Where "x" is any character not defined above) Silently swallowed, reserved for future use If not specified, the default forwardPattern is "$M$P", which is consistent with previous hard coded behavior of URL evaluation for "page" attributes. ["$M$P"]

processorClass The fully qualified Java class name of the RequestProcessor subclass to be used with this module. ["org.apache.struts.chain.ComposableRequestProcessor"]

tempDir Temporary working directory to use when processing file uploads. [{Directory provided by servlet container}]

Element identifier.

Possible values: Match the ID rules.

<set-property/> | Child of plug-in, message-resources, action, exception, form-property, forward, controller, form-bean

The "set-property" element specifies the method name and initial value of an additional JavaBean configuration property. When the object representing the surrounding element is instantiated, the accessor for the indicated property is called and passed the indicated value. The "set-property" element is especially useful when a custom subclass is used with <forward>, <action>, or <plug-in> elements. The subclass can be passed whatever other properties may be required to configure the object without changing how the struts-config is parsed.

Since Struts 1.3, an alternate syntax is supported. By using the "key" attribute instead of the "property" attribute, you can set arbitrary string properties on the Config object which is populated based on the containing element. NOTE: the "key" attribute is NOT supported for <set-property> inside a <plug-in> element.

property Name of the JavaBeans property whose setter method will be called. Exactly one of "property" or "key" must be specified.

key Where supported, the key which will be used to store the specified value in the given config object. Exactly one of "property" or "key" must be specified.

value String representation of the value to which this property will be set, after suitable type conversion
