soapHTTP error: com.wm.app.b2b.client.ns.NSRuntimeException

When I invoke soapHTTP, I got the following error:

com.wm.app.b2b.client.ns.NSRuntimeException

I have set the following params:
soapRequestData = a soapdata object
address = string that contains url
auth.user = administrator
auth.pass = manage
SOAPAction = a string

Is there any missing parts?

Thanks.

What version of IS? Have you installed the latest WebSvcs and ServerProtocol patches?

Are you attempting to invoke an operation provided by a .Net client over HTTPS?

I get the same error in 6.5 when stepping through a web service connector.
Stepping through I get a com.wm.app.b2b.client.ns.NSRuntimeException in pub.client.soapHTTP

Running it through (not stepping) I get a java.lang.NullPointerException
