We have an application that uses JRun and IIS. The
application has JSPs, servlets, java beans as well as
stored procedures. Database is MS-SQL Server. The
entire application was working well... till now.
Suddenly the main login page has started throwing a
404 error (and of course if we are not able to login,
there is no way we can access the rest of the
application). We renamed a regular HTML page and saved
it with .JSP extension. And then we couldn't make it
come up either. Essentially no JSP pages are being
served.
Due to pecularity of our situation, we have limited
access to production server. But the sys admin has
told us that no upgrades were performed on the machine
nor was any configuration changed. global.properties
and local.properties SEEM fine. No libraries SEEM to
be missing.
We looked through the default-event.log and see the
following messages-

So, how can an application work well one day and
suddenly stop working the next ? Would anybody know
the possible causes for receiving such error messages
and the application throwing a 404 ?
I looked through one of the technical articles on
Macromedia website and it mentioned the variable
<app-name>.use-webserver-root. The development server
also uses the IIS and I looked through the
local.properties file. It does not have this variable
set, which means it is "false" by default, which, in
turn, means that JRun should serve pages relative to
its root. Since our pages are in IIS root, this SHOULD
generate 404 error BUT IT DOESN'T. The application
works just fine on development. I explicitly set the
variable MYAPP.use-webserver-root = false so that JRun
throws error but it still served the pages correctly
in dev env. Not sure what is happening...
One of the things I noticed on the PRODUCTION
local.properties file is that it does not have the
line ejb.ejipt.enableMessaging=true. They are using
advanced edition. Could this be causing the problem ?
Thanks for your help.
