Include Tag

This tag has two uses:

  • It is used in a Site Template (a wrapper page) to indicate where to include the content of the page being visited.
  • It is used to include another JSP page stored on the platform. In that case, it can help to organize your pages. For example, common libraries can be declared on a single page--say, common.jsp. If that page is included everywhere, a new library can be added to every page simply by declaring in the common page.
