Is s:form specific to struts2 framework?

Is "s:fo开发者_Go百科rm" specific to the struts2 framework or can we use it in the struts1 framework also?

Tags in the "s" namespace (<s:XXX>) are specific to Struts2. You can't use the s: tags in Struts 1.

s:form is indeed specific to struts 2.0. The s namespace was first introduced in 2.0.
