As for Servlet 2.3 specifications, you could easily create a Servlet Filter which
would intercept all your requests based on your url-pattern (defined in web.xml), and
which would do something like :
RequestDispatcher reqDispatcher = request.getRequestDispatcher("header.jsp");
reqDispatcher.include(request, response);
And then let the filter forward to the requested page (chain.doFilter()). Thus all
your pages would include your header.jsp file (beware not to include header.jsp into
header.jsp file, or you'll get an infinite loop ;-) )
This is quite easy to implement and the best way IMHO. Have a look at the
http://java.sun.com web site for more info on Servlet Filters, they are very handy as
soon as you understand how they work.
Hope this helps,
Alain

Objet : Re: JSP suggestion
Or you can specify a prelude.jspf file in your web.xml (I think this may
only work with servlet spec 2.4 servers)
(The prelude is added to the top of the file, the coda is added to the
end of the file)
<jsp-config>
....
<jsp-property-group>
<display-name>allFiles</display-name>
<url-pattern>*.jsp</url-pattern>
<el-ignored>false</el-ignored>
<scripting-invalid>false</scripting-invalid>
<is-xml>false</is-xml>
<include-prelude>/template/prelude.jspf</include-prelude>
<include-coda>/template/coda.jspf</include-coda>
</jsp-property-group>
</jsp-config>
