Webservice error

Chris Diesel — Mon, 12 Jul 2010 10:02:10 GMT

I am getting a strange web service error message. We have had a web service and sql data hosted by Network Solutions running for about 6 months.

We have not made any code updates. On Monday morning, we started receiving this message when calling a web method that uses business objects.

For a test I tried adding a new web method that accessed the data directly via a sqlconnection, sqldataadaptor and dataset (no business object call). This method executes and returns the data without error.

Network Solutions said everything looks good from their end. ;)

Any ideas would be appreciated.

Unfortunately Network Solutions is not helping with this.

The following tests worked:

Access the same data from the web service method using ADO.NET
Call a DLL from the web service method that uses ADO.NET to access the same data

But when I try to use the FillDataTable or GetDataTable methods from my business object module, I get the above error. What are these methods doing different that would cause a SecurityException when ADO.NET does not?

Got it, Chris.

You are welcome! ;)

Network Solutions finally admitted that they are having issues.:w00t:

Thanks for your time!

It looks like the application attempted to perform an operation not allowed by the security policy. See if this points you in the right direction:

I upgraded the web service when I just published the test method. I don't have the original exception text from the prior version except in a screen shot (which I can't seem to find on my tidy desk). Best I can tell, this exception is the same as the original besides the version numbers.

Hi Chris.

Were you running on 1.7.0.0 before or have you just upgraded?
