| Page Construction Tags |
This taglib contains tags used to create struts
input forms, as well as other tags generally useful
in the creation of HTML-based user interfaces.
Many of the tags in this tag library will throw a
JspException at runtime when they are utilized incorrectly
(such as when you specify an invalid combination of tag attributes). JSP
allows you to declare an "error page" in the <%@ page %>
directive. If you wish to process the actual exception that caused the
problem, it is passed to the error page as a request attribute under key
org.apache.struts.action.EXCEPTION.

| base -
Render an HTML <base> Element |
Renders an HTML <base> element with an
href attribute pointing to the absolute location of
the enclosing JSP page. This tag is valid only when nested inside
an HTML <head> element.
This tag is useful because it allows you to use relative URL
references in the page that are calculated based on the URL of the
page itself, rather than the URL to which the most recent submit
took place (which is where the browser would normally resolve
relative references against).

Back to top | form -
Define An Input Form
|
Renders an HTML <form> element whose contents are described
by the body content of this tag. The form implicitly interacts
with the specified request scope or session scope bean to populate
the input fields with the current property values from the bean.
The associated form bean is determined in one of two ways:
-
If the
name and type attributes
are not specified, then the form bean will be located, and
created if necessary, based on the form bean specification
for the associated ActionMapping.
-
If the
name and type attributes
are specified, then the form bean will be located, and created
if necessary, using the specified values for name,
type and scope.
NOTE: The use of the name,
type and scope attributes is
deprecated. The preferred usage is to allow the appropriate
values to be determined automatically from the corresponding
ActionMapping.
| | Attribute Name | Description |
|---|
| action |
The URL to which this form will be submitted. This
value is also used to select the ActionMapping we are
assumed to be processing, from which we can identify
the appropriate form bean and scope.
If you are using extension mapping for selecting the
controller servlet, this value should be equal to the
path attribute of the corresponding
<action> element, optionally
followed by the correct extension suffix.
If you are using path mapping to select the
controller servlet, this value should be exactly equal
to the path attribute of the corresponding
<action> element.
(REQUIRED)
(RT EXPR)
| | enctype |
The content encoding to be used to submit this form, if the method
is POST. This must be set to "multipart/form-data" if you are using
the file tag to enable file upload. If not specified, the browser
default (normally "application/x-www-form-urlencoded") is used.
(RT EXPR)
| | focus |
The field name (among the fields on this form) to which initial
focus will be assigned with a JavaScript function. If not specified,
no special JavaScript for this purpose will be rendered.
(RT EXPR)

If the focus field is a field array, such as a radio button group, you can
specify the index in the array to receive focus.
(RT EXPR)
| | method |
The HTTP method that will be used to submit this request
(GET, POST). [POST]
(RT EXPR)
| | name | DEPRECATED:
The bean name will be determined from the corresponding
ActionMapping.
Name of the request scope or session scope bean
(as defined by the scope attribute)
whose properties will be used to populate the input
field values. If no such bean is found, a new bean
will be created and added to the appropriate scope,
using the Java class name specified by the
type attribute.
If this attribute is not specified, the name of the bean
will be calculated by using the value of the
action attribute to look up the
corresponding ActionMapping element, from which
the specified form bean name will be selected.
(RT EXPR)
| | onreset |
JavaScript event handler executed if the form is reset.
(RT EXPR)
| | onsubmit |
JavaScript event handler executed if the form is submitted.
(RT EXPR)
| | scope | DEPRECATED:
The bean scope will be determined from the corresponding
ActionMapping.
Scope within which the form bean associated with
this input form will be accessed or created (must be
either request or session).
If this attribute is not specified, the scope of the bean
will be calculated by using the value of the
action attribute to look up the
corresponding ActionMapping element, from which
the specified form bean scope will be selected.
(RT EXPR)
| | style |
CSS styles to be applied to this HTML element.
(RT EXPR)
| | styleClass |
CSS stylesheet class to be applied to this HTML element
(renders a "class" attribute).

| | target |
Window target to which this form is submitted, such as
for use in framed presentations.
(RT EXPR)
| | type | DEPRECATED:
The bean type will be determined from the corresponding
ActionMapping.
Fully qualified Java class name of the form bean to
be created, if no such bean is found in the specified
scope.
If this attribute is not specified, the type of the bean
will be calculated by using the value of the
action attribute to look up the
corresponding ActionMapping element, from which
the specified form bean type will be selected.

Back to top | frame -
Render an HTML frame element |
Renders an HTML <frame> element
with processing for the src attribute that is
identical to that performed by the <html:link>
tag for the href attribute. URL rewriting will be
applied automatically, to maintain session state in the
absence of cookies.
The base URL for this frame is calculated based on
which of the following attributes you specify (you must
specify exactly one of them):
- forward - Use the value of this attribute as the
name of a global
ActionForward to be looked
up, and use the application-relative or context-relative
URI found there.
- href - Use the value of this attribute unchanged.
- page - Use the value of this attribute as a
application-relative URI, and generate a server-relative
URI by including the context path and application
prefix.
- action - Use the value of this attribute as the
logical name of a global Action that contains the actual
content-relative URI of the destination of this transfer.
Normally, the hyperlink you specify with one of the
attributes described in the previous paragraph will be left
unchanged (other than URL rewriting if necessary). However,
there are two ways you can append one or more dynamically
defined query parameters to the hyperlink -- specify a single
parameter with the paramId attribute (and its
associated attributes to select the value), or specify the
name (and optional property)
attributes to select a java.util.Map bean that
contains one or more parameter ids and corresponding values.
To specify a single parameter, use the paramId
attribute to define the name of the request parameter to be
submitted. To specify the corresponding value, use one of the
following approaches:
- Specify only the
paramName attribute
- The named JSP bean (optionally scoped by the value of the
paramScope attribute) must identify a value
that can be converted to a String.
- Specify both the
paramName and
paramProperty attributes - The specified
property getter method will be called on the JSP bean
identified by the paramName (and optional
paramScope) attributes, in order to select
a value that can be converted to a String.
If you prefer to specify a java.util.Map that
contains all of the request parameters to be added to the
hyperlink, use one of the following techniques:
- Specify only the
name attribute -
The named JSP bean (optionally scoped by the value of
the scope attribute) must identify a
java.util.Map containing the parameters.
- Specify both
name and
property attributes - The specified
property getter method will be called on the bean
identified by the name (and optional
scope) attributes, in order to return the
java.util.Map containing the parameters.
As the Map is processed, the keys are assumed
to be the names of query parameters to be appended to the
hyperlink. The value associated with each key must be either
a String or a String array representing the parameter value(s),
or an object whose toString() method will be called.
If a String array is specified, more than one value for the
same query parameter name will be created.
Additionally, you can request that the current transaction
control token, if any, be included in the generated hyperlink
by setting the transaction attribute to
true.
You can also request that an anchor ("#xxx") be added to the
end of the URL that is created by any of the above mechanisms,
by using the anchor attribute.
| | Attribute Name | Description |
|---|
| action |

forward attribute, the
href attribute,
or the page attribute.

Back to top | img -
Render an HTML img tag |
Renders an HTML <img> element with
the image at the specified URL. Like the link tag, URL
rewriting will be applied automatically to the value
specified in src or page,
to maintain session state
in the absence of cookies. This will allow dynamic
generation of an image where the content displayed for this
image will be taken from the attributes of this tag.
The base URL for this image is calculated directly based on
the value specified in src or page,
or indirectly by looking up a message resource string based on
the srcKey or pageKey attributes.
You must specify exactly one of these
attributes.
Normally, the src or page that
you specify will be left
unchanged (other than URL rewriting if necessary). However,
there are two ways you can append one or more dynamically
defined query parameters to the src URL --
specify a single parameter with the paramId
attribute (at its associated attributes to select the value),
or specify the name (and optional
property) attributes to select a
java.util.Map bean that contains one or more
parameter ids and corresponding values.
To specify a single parameter, use the paramId
attribute to define the name of the request parameter to be
submitted. To specify the corresponding value, use one of the
following approaches:
- Specify only the
paramName attribute
- The named JSP bean (optionally scoped by the value of the
paramScope attribute) must identify a value
that can be converted to a String.
- Specify both the
paramName and
paramProperty attributes - The specified
property getter will be called on the JSP bean identified
by the paramName (and optional
paramScope) attributes, in order to select
a value that can be converted to a String.
If you prefer to specify a java.util.Map that
contains all of the request parameters to be added to the
hyperlink, use one of the following techniques:
- Specify only the
name attribute -
The named JSP bean (optionally scoped by the value of
the scope attribute) must identify a
java.util.Map containing the parameters.
- Specify both
name and
property attributes - The specified
property getter method will be called on the bean
identified by the name (and optional
scope) attributes, in order to return the
java.util.Map containing the parameters.
As the Map is processed, the keys are assumed
to be the names of query parameters to be appended to the
src URL. The value associated with each key
must be either a String or a String array representing the
parameter value(s), or an object whose toString() method
will be called. If a String array is specified, more than
one value for the same query parameter name will be
created.
You can specify the alternate text for this image (which
most browsers display as pop-up text block when the user
hovers the mouse over this image) either directly, through
the alt attribute, or indirectly from a message
resources bundle, using the bundle and
altKey attributes.
| | Attribute Name | Description |
|---|
| align |
Where the image is aligned to. Can be one of the
following attributes:
- left - left justify, wrapping text on right
- right -right justify, wrapping test on left
- top - aligns the image with the top of the text on
the same row
- middle - aligns the image's vertical center with the
text base line
- bottom - aligns the image with the bottom of the
text's base line
- texttop - aligns the image's top with that of the
text font on the same line
- absmiddle - aligns the image's vertical center with the
absolute center of the text
- absbottom - aligns the image with the absolute bottom
of the text font on the same row

The set of validation rules that should be generated is based
on the formName attribute passed in, which should match
the name attribute of the form element in the xml file.
The dynamicJavascript and staticJavascript attributes
default to true, but if dynamicJavascript is set to true
and staticJavascript is set to false then only
the dynamic JavaScript will be rendered. If dynamicJavascript
is set to false
and staticJavascript is set to true then only
the static JavaScript will be rendered which can then be put in
separate JSP page so the browser can cache the static JavaScript.
| | Attribute Name | Description |
|---|
| cdata | Since: Struts 1.1

Back to top | link -
Render an HTML anchor or hyperlink |
Renders an HTML <a> element as an
anchor definition (if "linkName" is specified) or as a
hyperlink to the specified URL. URL rewriting will be
applied automatically, to maintain session state in the
absence of cookies. The content displayed for this
hyperlink will be taken from the body of this tag.
The base URL for this hyperlink is calculated based on
which of the following attributes you specify (you must
specify exactly one of them):
- forward - Use the value of this attribute as the
name of a global
ActionForward to be looked
up, and use the application-relative or context-relative
URI found there.
- action - Use the value of this attribute as the
name of a
Action to be looked
up, and use the application-relative or context-relative
URI found there.
- href - Use the value of this attribute unchanged.
- page - Use the value of this attribute as a
application-relative URI, and generate a server-relative
URI by including the context path and application
prefix.
Normally, the hyperlink you specify with one of the
attributes described in the previous paragraph will be left
unchanged (other than URL rewriting if necessary). However,
there are two ways you can append one or more dynamically
defined query parameters to the hyperlink -- specify a single
parameter with the paramId attribute (and its
associated attributes to select the value), or specify the
name (and optional property)
attributes to select a java.util.Map bean that
contains one or more parameter ids and corresponding values.
To specify a single parameter, use the paramId
attribute to define the name of the request parameter to be
submitted. To specify the corresponding value, use one of the
following approaches:
- Specify only the
paramName attribute
- The named JSP bean (optionally scoped by the value of the
paramScope attribute) must identify a value
that can be converted to a String.
- Specify both the
paramName and
paramProperty attributes - The specified
property getter method will be called on the JSP bean
identified by the paramName (and optional
paramScope) attributes, in order to select
a value that can be converted to a String.
If you prefer to specify a java.util.Map that
contains all of the request parameters to be added to the
hyperlink, use one of the following techniques:
- Specify only the
name attribute -
The named JSP bean (optionally scoped by the value of
the scope attribute) must identify a
java.util.Map containing the parameters.
- Specify both
name and
property attributes - The specified
property getter method will be called on the bean
identified by the name (and optional
scope) attributes, in order to return the
java.util.Map containing the parameters.
As the Map is processed, the keys are assumed
to be the names of query parameters to be appended to the
hyperlink. The value associated with each key must be either
a String or a String array representing the parameter value(s),
or an object whose toString() method will be called.
If a String array is specified, more than one value for the
same query parameter name will be created.
Additionally, you can request that the current transaction
control token, if any, be included in the generated hyperlink
by setting the transaction attribute to
true.
You can also request that an anchor ("#xxx") be added to the
end of the URL that is created by any of the above mechanisms,
by using the anchor attribute.

prefer to combine the values into a single
array-valued property instead of multiple boolean
properties. This tag is only valid when nested
inside a form tag body.
WARNING: In order to correctly
recognize cases where none of the associated checkboxes
are selected, the ActionForm bean
associated with this form must include a statement
setting the corresponding array to zero length in the
reset() method.
The value to be returned to the server, if this checkbox is
selected, must be defined by one of the following methods:
- Specify a
value attribute, whose contents will
be used literally as the value to be returned.

Back to top | options -
Render a Collection of Select Options
|
Renders a set of HTML <option> elements,
representing possible choices for a <select>
element. This tag can be used multiple times within a single
<html:select> element, either in conjunction
with or instead of one or more <html:option>
or <html:optionsCollection> elements.
This tag operates in one of two major modes, depending on
whether or not the collection attribute is
specified. If the collection attribute is
included, the following rules apply:
- The collection attribute is interpreted
as the name of a JSP bean, in some scope, that itself
represents a collection of individual beans, one per option
value to be rendered.
- The property attribute is interpreted as
the name of a property of the individual beans included in
the collection, and is used to retrieve the value that will
be returned to the server if this option is selected.
- The labelProperty attribute is interpreted
as the name of a property of the individual beans included
in the collection, and is used to retrieve the label that
will be displayed to the user for this option. If the
labelProperty attribute is not specified, the
property named by the property attribute will
be used to select both the value returned to the server and
the label displayed to the user for this option.
If the collection attribute is not specified,
the rules described in the remainder of this section apply.
The collection of values actually selected depends on the presence or
absence of the name and property attributes. The
following combinations are allowed:
- Only
name is specified - The value of this attribute
is the name of a JSP bean in some scope that is the
collection.
- Only
property is specified - The value of this
attribute is the name of a property of the ActionForm bean associated
with our form, which will return the collection.
- Both
name and property are specified -
The value of the name attribute identifies a JSP bean
in some scope. The value of the property attribute is the
name of some property of that bean which will return the collection.
The collection of labels displayed to the user can be the same as the
option values themselves, or can be different, depending on the presence or
absence of the labelName and labelProperty
attributes. If this feature is used, the collection of labels must contain
the same number of elements as the corresponding collection of values.
The following combinations are allowed:
- Neither
labelName nor labelProperty is
specified - The labels will be the same as the option values
themselves.
- Only
labelName is specified - The value of this
attribute is the name of a JSP bean in some scope that is the
collection.
- Only
labelProperty is specified - The value of this
attribute is the name of a property of the ActionForm bean associated
with our form, which will return the collection.
- Both
labelName and labelProperty are
specified - The value of the labelName attribute
identifies a JSP bean in some scope. The value of the
labelProperty attribute is the name of some property of
that bean which will return the collection.
Note that this tag does not support a styleId
attribute, as it would have to apply the value to all the
option elements created by this element, which would
mean that more than one id element might have the same
value, which the HTML specification says is illegal.
| | Attribute Name | Description |
|---|
| collection |
Name of the JSP bean (in some scope) which is itself a
Collection of other beans, each of which has properties
named by the "property" and "labelProperty" attributes
that are used to retrieve the value and label for each
option, respectively.

Render a Collection of Select Options
|
Renders a set of HTML <option> elements,
representing possible choices for a <select>
element. This tag can be used multiple times within a single
<html:select> element, either in conjunction
with or instead of one or more <html:option>
or <html:options> elements.
This tag operates on a collection of beans, where each bean
has a label property and a value
property. The actual names of these properties can be configured
using the label and value attributes
of this tag.
This tag differs from the <html:options> tag
in that it makes more consistent use of the name and
property attributes, and allows the collection to be
more easily obtained from the enclosing form bean.
Note that this tag does not support a styleId
attribute, as it would have to apply the value to all the
option elements created by this element, which would
mean that more than one id element might have the same
value, which the HTML specification says is illegal.

Render A Select Element
|
Renders an HTML <select> element, associated
with a bean property specified by our attributes. This
tag is only valid when nested inside a form tag body.
This tag operates in two modes, depending upon the
state of the multiple attribute, which
affects the data type of the associated property you
should use:
- multiple="true" IS NOT selected -
The corresponding property should be a scalar
value of any supported data type.
- multiple="true" IS selected -
The corresponding property should be an array
of any supported data type.
WARNING: In order to correctly
recognize cases where no selection at all is made, the
ActionForm bean associated with this form
must include a statement resetting the scalar property
to a default value (if multiple is not
set), or the array property to zero length (if
multiple is set) in the
reset() method.
