How to emulate nested:root from Struts 1 in Struts 2?

Question

I am working on converting a Struts1 app to Struts2. I have a jsp that has several JSP included. This included JSPs all have the nested:root tag on it.

Answer 1

All nested tags and all Struts1 tags should be removed/replaced with equivalent Struts2 tags.

Nested tags not needed in Struts2 because it's powered with OGNL. Using OGNL expressions and allows to replace nested tags.

If it's not enough to render content with s:include you can use but it's heavy and it recreates a valueStack when this tag executes, so it's rarely used, but custom tags or custom components that include Fremarker or Velocity templates can significantly change the rendering time and allows customization.
