getting exception trying to connect to https with jars:client

Hi,

I am trying to connect to a rest full service using jaxrs client and I get
the following exception:

javax.ws.rs.ProcessingException: javax.net.ssl.SSLHandshakeException:
SSLHandshakeException invoking
https://10.120.10.11/services/consumer/datasource/consumer:
sun.security.validator.ValidatorException: PKIX path building failed:
sun.security.provider.certpath.SunCertPathBuilderException: unable to find
valid certification path to requested target

how can bypass the validation of ssl?

The code I using looks like the following:

<jaxrs:client id="dsiClient" address="${url}"
serviceClass="ConsumerServiceResource"
username="admin" password="admin">

Thanks,
Ali
