Allow soapUI to ignore invalid SSL certificates

I have a REST web service that is accessed via HTTPS. The problem is that the certificate returned by the web service is for a different domain than is used to access the web service. When I try to specify the WADL for the web service, I get the following error (expected):

javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Again, this is because the certificate is for host x.y.com but the hostname is currently x1.y1.com. I recognize that the ultimate solution is to associated the appropriate hostname with the host, but I don't have the ability to do that right now.

Instead, is there any way to get soapUI to ignore invalid SSL certificates?

Thanks,
Jay
