web service wrapper error

Here, I failed to use the component SOAP Method with WSDL Support to wrap a webservice (http://www.ncbi.nlm.nih.gov/entrez/eutils/soap/eutils.wsdl ). The error is WSDLs with external types are not supported. If I change another method name, the error is Can't find schema with targetNamespace=www.ncbi.nlm.nih.gov/soap/eutils/egquery.

more information could be seen from http://www.ncbi.nlm.nih.gov/entrez/query/static/esoap_help.html.

Is there any idea?
Thanks.
