If you're just including raw HTML, use the #include DIRECTIVE as usual inside your .jsp file.

But it's a little trickier if you want the SERVER to evaluate any JSP code that's inside the included file. If your data.inc file contains jsp code you will have to use <%@ vinclude="data.inc" %>

The is used for including non-JSP files.

include directive - <%@ include file="fileName" %> - as is the case with all other directives in a JSP page, this include directive is also PROCESSED at the time when the JSP page is translated into its equivalent servlet. This directive simply causes the contents of the specified file to be pasted into the JSP page at the place where the page contains this directive. Irrespective of whether the included resource is a static resource or a JSP page - only the contents of the file are pasted (and not the processed results). This directive is normally used for including static resources only - like, banner, header, footer, etc. for the obvious reason.

include action -<jsp:include page="relativeURL"></jsp:include> this include action is executed at run time and the specified 'page' is first executed and then the result of that 'page' is appended to the response object of the calling JSP at the point where the tag OCCURS. Obviously if the specified page is a static resource then the contents of it are included as there won't be an executed result in that case. This action allows additional parameters to be passed via child element of this include action element.
