Please make sure you have read the Tag Syntax document and understand how tag attribute syntax works.

Description

Content pulled from external source. Click here to refresh.

This tag enables developers to call actions directly from a JSP page by specifying the action name and an optional namespace. The body content of the tag is used to render the results from the Action. Any result processor defined for this action in xwork.xml will be ignored, unless the executeResult parameter is specified.
