SOA Suite is unable to read the WSDL due to a HTTP error (code 407, Proxy Authentication Required)

Question

in my composite I inserted a web service. For the WSDL URL of this service I tried to use a link to a document in my company's intranet (http://10.30.3.162/host/sap?wsdl). After that an error message popped up:

Error while reading wsdl file http://10.30.3.162/host/sap?wsdl. Exception:
   WSDLException: faultCode=OTHER_ERROR: Failed to read WSDL from
   http://10.30.3.162/host/sap?wsdl: HTTP connection error code is 407

We use a proxy server in our company, so that might be the reason for this error, but I added "10.*" as an exception in my internet options. Also if I open the link in a web browser it shows the WSDL file. I made sure that the option "Use HTTP Proxy Server" in the SOA Suite preferences is not checked. I also tried with a checked box, alas with the same result.

Do you guys have any idea what might cause this? I do realize that this probably is a very unique problem...

When re-opening the composite there's a bit more detailed error message:

Failed to find WSDL definition and/or locate WSDL file:
  - WSDLException: faultCode=OTHER_ERROR: Failed to read WSDL from
    http://10.30.3.162/host/sap?wsdl: HTTP connection error code is 407
  oracle.j2ee.ws.wsdl.LocalizedWSDLException: WSDLException:
  faultCode=OTHER_ERROR: Failed to read WSDL from http://10.30.3.162/host/sap?wsdl: 
  HTTP connection error code is 407

Thanks a lot for any help!

EDIT: Oh snap.. I totally forgot to add the version of the software I use: Oracle JDeveloper 11g Release 1 11.1.1.5.0

To check if it is a proxy issue, try accessing the WSDL from a command line.

E.g. in a Linux box: curl http://10.30.3.162/host/sap?wsdl

You should get the WSDL or an error if you have a proxy issues.
