[Mono-list] How to debug SOAP webservice

[Andrus]

I created SOAP webservice with works OK from VS IDE.

When this web service is hosted in mod_mono/Apache, calling it returns 
error:

<?xml version="1.0" encoding="utf-8"?><soap:Envelope 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Body><soap:Fault><faultcode>soap:Server</faultcode><faultstring>Exception 
has been thrown by the target of an 
invocation.</faultstring></soap:Fault></soap:Body></soap:Envelope>

I want to find stack trace or line number causing exception.

I tried the following:

1. Invoked  mod-mono-server  in console window using

c:\mono/bin/mod-mono-server.bat --address 127.0.0.1 --port 
2000 --applications /:./ --nonstop --root 
I:/raamat/MyAppWeb/SilverlightApplication4_Web --master --verbose

Console window shows some output from web service but does not show any 
information
about exception nor exception text.

2. In web.config file setting debug to true:

            <compilation debug="true" defaultLanguage="c#" explicit="true" 
strict="false" >


output text nor console output are not changed.

How to determine which line of code causes exception or find stack trace ?
