SOAP error accessing wm soap listener from MS-SOAP 2.0

Hi,

I am trying to access a webMethods b2b flow from an ASP page suing SOAP. I have a MS-SOAP 2.0 client and I have custom listener in my b2b server. While I try to access the custom listener in the b2b server, I get an exception in the server.log as follows:

000035 [B2BCORE.0088.0001] SOAPException: [B2BSERV.0088.9112] An Exception was thrown in the server

I am able to use the same ASP client to access a MS-SOAP based server(listener) and I am also able to use the same b2b listener using webmethods soapHTTP as a client.

Is there some setting necessary for remote soap calls especially regarding security. Are there any documents regarding accessing wm SOAP servers from other applications? Any pointers would be welcome…

thanks,
