Tag redirect


Render an HTTP Redirect

Performs an HttpServletResponse.sendRedirect() call to the hyperlink specified by the attributes to this tag. URL rewriting will be applied automatically, to maintain session state in the absence of cookies.

The base URL for this redirect is calculated based on the href

Normally, the redirect 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 hyperlink -- specify a single parameter with the paramId attribute (and its associated attributes to select the value), or specify the name attribute to select a SourceBean list 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, specify the paramName attribute - The named property on service context (optionally scoped by the value of the paramScope attribute) must identify a value that can be converted to a String.

If you prefer to specify a SourceBean list that contains all of the request parameters to be added to the hyperlink, specify only the name attribute - The named service context data (optionally scoped by the value of the scope attribute) must identify a SourceBean list containing the parameters.

As the SourceBean list is processed, every element is assumed to be formed by the name and value attributes; these respective values are used as query parameters to be appended to the hyperlink. The value associated with each SourceBean must be either a String or an object whose toString() method will be called.

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 the href is calculated based on the alias and aliasRelated parameters.

Attributes
NameRequiredRequest-timeTypeDescription
aliasfalsetruejava.lang.StringName of the alias to be used instead of the href attribute.
aliasRelatedfalsetruejava.lang.StringString to be appended to the alias attribute if present.
anchorfalsetruejava.lang.String

Optional anchor tag ("#xxx") to be added to the generated hyperlink. Specify this value without any "#" character.

hreffalsetruejava.lang.String

The URL to which this redirect will transfer control. This URL may be dynamically modified by the inclusion of query parameters, as described in the tag description. You must specify exactly one of the forward attribute, the href attribute, the linkName attribute, or the page attribute.

namefalsetruejava.lang.String

The name of a JSP bean that contains a Map representing the query parameters (if property is not specified), or a JSP bean whose property getter is called to return a Map (if property is specified).

paramIdfalsetruejava.lang.String

The name of the request parameter that will be dynamically added to the generated hyperlink. The corresponding value is defined by the paramName and (optional) paramProperty attributes, optionally scoped by the paramScope attribute

paramNamefalsetruejava.lang.String

The name of a JSP bean that is a String containing the value for the request parameter named by paramId (if paramProperty is not specified), or a JSP bean whose property getter is called to return a String (if paramProperty is specified). The JSP bean is constrained to the bean scope specified by the paramScope property, if it is specified.

paramScopefalsetruejava.lang.String

The scope within which to search for the bean specified by the paramName attribute. If not specified, all scopes are searched.

scopefalsetruejava.lang.String

The scope within which to search for the bean specified by the name attribute. If not specified, all scopes are searched.

transactionfalsetrueboolean

Set to true if you want the current transaction control token included in the generated URL for this redirect.

useLocalEncodingfalsetrueboolean

If set to true, LocalCharacterEncoding will be used, that is, the characterEncoding set to the HttpServletResponse, as prefered character encoding rather than UTF-8, when URLEncoding is done on parameters of the URL.
