Testing WebService(SOAP) Request in HTTPS protocol

[Ali Navab <sa...@gmail.com>]

Hi all,
I recently install JMeter for Load and Performance Testing a
WebApplications and WebServices. every thing is ok and help embedded but a
qustion:

When i want to test my webService using "WebService(SOAP) Request", can not
solve the error.

my webserver is "apache-tomcat-6.0.26" and the address of webservice i want
to load test is:
https://localhost:8443/.../../Re..WebServiceImpl?WSDL<https://localhost:8443/Re..WebServiceImpl?WSDL>

Because of https protocol, i gave the key to JMeter using Option>SSL Manager

but it still return ssl error (i think!)
The exact error is :
Response message: Error opening socket: 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

It will be really appreciated if any one give me some hint about it. and
would be useful for another beginner :)
