NOTE: The following attributes are defined by the default data source implementation, and only take effect for that class or subclasses of that class.

WARNING: The use of these attributes is deprecated. You should use nested <set-property> elements to configure *all* properties of your data source implementation.

autoCommit The default auto-commit state for newly created connections.

description The description of this data source.

driverClass The Java class name of the JDBC driver to be used. [REQUIRED]

The "global-forwards" element configures the global mappings of logical names (used within the application) to mappable resources (identified by context-relative URI paths). A global "forward" with a particular name can be locally overridden by defining a "forward" of the same name within an "action" element. The following attribute are defined:

type Fully qualified Java class name of the implementation class used for ActionForward objects. DEPRECATED.

WARNING: For Struts 1.0, this value is ignored. You can set the default implementation class name with the "forward" initialization parameter to the Struts controller servlet.

name Unique identifier of this forward, used to reference it in application action classes.

path The context-relative path of the mapped resource.

redirect Set to "true" if sendRedirect() should be used to forward to this resource, or "false" in order to use RequestDispatcher.forward() instead.

The "action-mappings" element configures the mappings from submitted request paths to the corresponding Action classes that should be used to process these requests. The following attributes are defined:

type Fully qualified Java class name of the ActionMapping implementation class to be used. DEPRECATED.

WARNING: For Struts 1.0, this value is ignored. You can set the default implementation class name with the "mapping" initialization parameter to the Struts controller servlet.

<action-mappings>'s children Name Cardinality action Any number

<action-mappings>'s attributes Name Values Default id Match the ID rules. type org.apache.struts.action.ActionMapping

The "action" element describes a mapping from a request paths to the corresponding Action classes that should be used to process these requests. The following attributes are defined:

attribute Name of the request-scope or session-scope attribute under which our form bean is accessed, if it is other than the bean's specified "name". Optional if "name" is specified, else not allowed.

className Fully qualified Java class name of the ActionMapping implementation class to use. Defaults to the value configured as the "mapping" initialization parameter to the Struts controller servlet.

forward Context-relative path of the servlet or JSP resource that will process this request, instead of instantiating and calling the Action class specified by "type". Exactly one of "forward", "include", or "type" must be specified.

include Context-relative path of the servlet or JSP resource that will process this request, instead of instantiating and calling the Action class specified by "type". Exactly one of "forward", "include", or "type" must be specified.

input Context-relative path of the input form to which control should be returned if a validation error is encountered. 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. Not allowed if "name" is not specified.

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

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

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

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

scope Identifier of the scope ("request" or "session") within which our form bean is accessed, if any. Optional if "name" is specified, else not allowed.

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

type Fully qualified Java class name of the Action class (implements org.apache.struts.action.Action) to be used to process requests for this mapping if the "forward" or "include" attribute is not included. Exactly one of "forward", "include", or "type" must be specified.

unknown Set to "true" if this action should be configured as the default for this application, to handle all requests not handled by another action. Only one action can be defined as a default within a single application.

validate Set to "true" if the validate() method of the form bean should be called prior to calling this action, or set to "false" if you do not want validation performed.

property Name of the JavaBeans property whose setter method will be called.

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