Hi,
Can anyone please help me in resolving this issue.

I have an eclipse galileo IDE . In that i m trying to test the web service in the web services explorer.

https://ccmuat.ultimatix.net/scpghd/servicerequest.asmx?wsdl .... this is URL.

But i m facing an error when testing this URL

ERROR : IWAB0379E Unable to open https://ccmuat.ultimatix.net/scpghd/servicerequest.asmx?wsdl.
IWAB0135E An unexpected error has occurred.
WSDLException
WSDLException: faultCode=OTHER_ERROR: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Any idea about this error ?
