<!-- The "controller" element describes the ControllerConfig bean
[org.apache.struts.config.ControllerConfig] that encapsulates
a module's runtime configuration. The following
attributes are defined:
bufferSize The size of the input buffer used when processing
file uploads.
[4096]
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}]
