Empty treeview

rbuser

At one of our customers we get an unexpected result. The explorer frameset
opens, but both frames (Including the treeview frame) are empty. When
looking in the source code, there is nothing between the tags
in the treeview.

We are using the ISAPI-tier.

Does anyone have any suggestion what might be wrong, or how this can be
resolved?

Do you get a page not found error? or just empy pages.

An empty page would indicate that no report volumes are registered with the
server. Check the report server application.

An empty explorer with two page not found errors indicates a configuration
issue. Check the webtier properties and the IIS and security accounts.

RB WebTier and IIS User Accounts
----------------------------------------

Question: I am trying to configure and test the RB WebTier using IIS. When
I try to test the web tier via my web browser an Internal Server 500 Error
page is displayed.

This is generic error page returned by IIS.

One cause of this error is that the WebTier application does not have
sufficient user access rights.


Solution:

1. Unload the WebTier application.

Use IIS to access the properties dialog for the rbWebPub virtual directory.
Press the UnLoad button to unload the ISAPI dll.

2. Delete rbWebPub subdirectories

Use Windows Explorer to delete all subdirectories inside the rbWebPub
directory. If you are using different WebTier CacheDirectory or WebTier
LogSettings, then delete those directories also.


3. Configure IIS User Accounts

There are two user accounts created by IIS: IUSR_MachineName and
IWAM_MachineName. (MachineName is replaced by the name of your computer).

a. Use Windows Explorer to access the properties dialog for the rbWebPub
directory.

b. Check whether the IUSR_MachineName and IWAM_MachineName accounts appear
in the list of users. If not then add them.

c. The IUSR_MachineName account is the Internet Guest Account. This account
requires Read, Execute, and Write access to rbWebPub.

d. The IWAM_MachineName account is a user account that IIS uses to run web
applications such as the web tier. This account requires full control of the
rbWebPub directory. The web tier must be able to read, write, and create new
files and sub directories for the CacheDirectory and the Log. Therefore if
you configure the WebTier to use directories that are not subdirectories of
rbWebPub, you will need to configure those directories as well.

e. reboot the machine.

This is a tough one for me to diagnose. There has to be a difference between
what is running at the other customer sites and what is running at this
particular site.

We have had no other reports from customers of any issues like this.

As a test, try creating a simple client application that asks the server for
the report catalog information. For an example, check out
RBuilder\Demos\Clients\ReportCatalog\ and the online help topics for
TrsClientReportCatalog.

Do you have a server deployment license for each server installation?
