How to "include" across contexts/webapps?

[Daishi Harada <da...@CS.Berkeley.EDU>]

Hi,

I have what seems like (and probably is) a very simple problem, but I
haven't been able to find a solution. Any help/hints would be
appreciated.

I'm trying to build a website in a typical sort of way, with headers
and footers isolated and "<%@include%>"'ed into the actual
pages. However, now I'd like to modularize somewhat and decompose
parts of the site into their own projects/contexts, while still having
each project share common headers and footers. Unfortunately,
"<%@include%>" is relative to the current context, so I haven't been
able to figure out a good way to share the header/footer information
across each of the contexts/apps. Is there a canonical way of doing
something like this?

TIA,
Daishi

You might take a look at the JSTL (JSP Standard Tag Library) at
<http://jakarta.apache.org/taglibs/doc/standard-doc/intro.html>.  It includes
an "import" tag that specifies a URL, which can point anywhere, either relative
or absolute.  I have not used this.

spectorsoft on machine which track down all events and
mail and password and makes a report...

my boss has hacked my account also he is so rich i
can't thought of logging a fir against him

i request u plz mail to spectorsoft abt the event and
ask them why don't they ensure that every client of

Hi

If you work on UNIX make one directory with the common files and
in each of apps directories make symbolic links to the common dir.
If you modify a file in a common dir you see the changes in all apps
without committing and updating CVS. And you do not need extra
disk space.

The fact that includes are context-relative is in the Servlet and JSP
specifications, so we cannot change it.

In my own apps, I accomplish your goal in an indirect manner -- I keep a
single copy of the shared header/footer files in a CVS repository that is
separate from my Tomcat webapps directory.  Then, as part of deploying a
particular webapp, I copy in the shared files out of this repository into
*each* webapp that requires them.  That way, I still have a single source
file to change in case updates are needed, at the (insignificant) cost of
a little extra disk space.
