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"

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
