Note: As of Struts 1.1 the template library has been deprecated in favor of Tiles.
The "struts-template" tag library contains tags that are useful in creating dynamic JSP templates for pages which share a common format. These templates are best used when it is likely that a layout shared by several pages in your application will change. The functionality provided by these tags is similar to what can be achieved using standard JSP include directive, but are dynamic rather than static.
