Description

This tag is used to create a URL.

You can use the <param> tag inside the body to provide additional request parameters. If the value of a param is an Array or an Iterable all the values will be added to the URL.

NOTE:

By default request parameters will be separated using escaped ampersands (i.e., &amp. This is necessary for XHTML compliance, however, when using the URL generated by this tag with the <s:property> tag, the escapeAmp attribute should be used to disable ampersand escaping.

NOTE:

When includeParams is 'all' or 'get', the parameter defined in a <param> tag will take precedence over any params included due to the includeParams attribute. For example, in Example 3 below, if there is a id parameter in the url where the page this tag is included like http://<host>:<port>/<context>/editUser.action?id=3333&name=John the generated url will be http://<host>:<port>/<context>/editUser.action?id=22&name=John because the parameter defined in the param tag will take precedence.

Setting a default value for includeParams

The property struts.url.includeParams can be used to set the default value of the includeParams attribute.

See Constant Configuration for further information.
