Getting "Unbalanced ELEMENT got:body expected:h1" errors -- help! - Weblogic

I've created a simple "HelloWorld" web service, and a matching client. The=
WSDL appears correct (I have validated it on some web-based XML validators=
), and I can ask the web service for the WSDL, which it returns properly.

However, when I make my simple call to the service from the client, I get t=
he below stacktrace. Can anyone suggest to me what might be causing this? =
I'm at a loss right now about it; namespace conflicts, perhaps?
