In case of servlets
get the servlet context(sc =
ServletContext.getContext(/myhost/sim/index.html)) of other web
application and there by get the Request
dispatcher(sc.getRequestDispacher(relativeUrl to /myhost/sim) ) and
forward.
I think in case of JSPs
response.sendRedirect(with obsolute url) will work

Subject: Multi web-application navigation
Hi,
I am working in a project which does use the Front-Controller J2EE
pattern
for controlling the navigation. It works with a servlet which accept
virtual
links for navigation. So instead of calling /myhost/cash/sample.jsp we
call
/myhost/cash/sample.event. When the servlet receives request to
/myhost/cash/sample.event, it can choose to display content from an HTML
page, a JSP page, or even a servlet. We have multiple web application
which
deploy this servlet for navigation.
Now the problem comes when I want to navigate from one web-application
to
another web-application. For example I want to navigate from
/myhost/cash
application to /myhost/sim/ posting a /myhost/sim/sample1.event. The
request
goes to servlet of the same servlet context ie. of /myhost/cash and the
request URI it gets becomes /myhost/cas/myhost/sim/sample1.event which
does
not exist in the system and I get an exception.
I have worked on a work-around which extracts the web-application id
from
request.getRequestURI() as /myhost/sim, gets the servlet context of this
web-applicaion and forward it using the request dispatcher of
/myhost/sim
application.
But the question arise how does JSP engine works. If I want to navigate
from
one web-application JSP to another web-application JSP, it does allow me
to
do it.
Is there any methodology by which it can be assured that it is invoking
the
right servlet of right web-application. So if I fire
/myhost/sim/sample1.jsp
from /myhost/cash web-application, it should get the servlet of
/myhost/sim
not of /myhost/cash.
Many Thanks,
-ShriKant
