Error getting output from Webservice that uses SoapExtension

ASMX Web Services and XML Serialization

Deepa Ravikumar

I'm getting the following error (eg 1) while invoking a webmethod that uses SoapExtension. I could trace into the ProcessMessage function (example - http://msdn.microsoft.com/msdnmag/issues/03/03/WebServices/) and the appOutputStream contains data, but is generating the error below. I've written the appOutputstream before copying to file attached below (eg 2). Can someone please help me in investigating and fixing this

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

rfreire

Sure,

Could you please post the code of your SoapExtension so I can see what's wrong

Is the WS working properly if you disable the extension

Rgds,

Rodrigo
