Access violation appeared in WebTier

rbuser

Everything was fine before couple of weeks ago but now my isapi dll is
generating access violation error.
There is no code change there is no installed firewall or antivirus program
on my server. My server is 2003 rc2. My rb version is 10.07 with delphi 7
I tried these steps and in every step I tried again, but nothing happen.
just I am getting AV (weException)

while there is no installed printer I disabled print spool service.
re-enabled spool service
installed a laser printer and set as default.
Operation system is up to date.

Can you help me ?

Something on your system must have changed.

Try setting WebTier.LogSettings.Verbose set to True and rebuild the project.
Then check the WebTier log, perhaps that will provide a clue.

This is a multi-part message in MIME format.

I know this address line is not correct but this one is also generate AV
http://www.myreportserver.com/intranet/rbWebPub/report.asp?content=viewer&volume=WebReports&name=noreport

There is no report name as "noreport"

I looked at the log, but cannot determine much. There are no exceptions
logged. According to the log you are using a Server Farm - is that correct?
Your Cache directory shows one session with a report explorer. One session
with a report. And one session that is emtpy.

Make sure you build the report server and the webtier with the exact same
version of Delphi and RB.

You say you are using RB 10.07, try updating to RB 10.09, which is the last
produced release for RB 10.x. Then rebuild both the server and webtier and
retest.

You could aslo try running the Demos\WebTier\WebDebug project using the
Delphi web debugger.See the ReadMe.txt included in the same folder.

I tested that against our live report server and did not encounter any
issue, other than an error generated by the report server

Here is the test I used

http://www.digital-metaphors.com/rbWebPub/Report.dll?content=viewer&volume=Archives&name=noreport

This error was displayed in the browser

Server Error: Processing request for report Archives\noreport
ReportServiceProvider Error: No report found in catalog:
Archives\noreport

Do you have any custom code on your report server? If so perhaps that could
be causing an issue.

In you test, you are not specifying a SessionID. I mention this because if
you call reports programmatically like this you really should use a
sessionID for efficiency.
