Call to GetService<OrderTracking> Failing

[roteague]

I've got a strange one here that I haven't been able to resolve. I've got a code module, where the following line:

Code: Select all

ot = server.GetService<OrderTracking>();

is failing. It throws a null exception (Object reference not set to an instance of an object) whenever I call it. What could cause this call to fail?

I've validated that SelectServer object is not null and contains the correct uri to connect to. Likewise, the User Name and Password are also correct. The code works in the development environment (Windows XP), but fails on the server (Windows 2003 Server).

I suspect it may be related to a security issue, since I get errors trying to write to the event log. The module is part of a WCF service (I'm building an Order Notification Handler), running under IIS.

Here is the Stack Trace (from the Event Log):

Code: Select all

SoftProOrderActivity::Execute - Looking up Order #: 09001003 failed. Error: Object reference not set to an instance of an object.. Stack Trace:    at SoftPro.Select.Client.SelectServer.InitLegacySupport()

What version of Select are you running?

[roteague]

Sorry, it's version 2.3.30216.50. I keep forgetting you guys are working multiple versions.

Could you provide a listing of the Select services that are installed on that Select Server ?

sps services /s:yourserveraddress

Is there anything in the Event Log immediately prior to the Error you've reported (perhaps a warning or another error)? Or is the one error all that you see?

Mark,

There are no errors either before or after. The only event log entries are: "Select Server started successfully." before the call and "Select Server stopped successfully." just after the call. Both are Information level entries.

In your 2003 environment, where are you placing your custom developed code? Are you copying our dlls into your folder, or are you placing you dlls into the SoftPro installation folder?

We don't have the SoftPro client installed on this machine, so I've taken to copying all the dll's from a client install to the server. The server install is under the InetPub directory since it is part of a WCF service.
