unable to find valid certification path to requested target

hi,all.

It's an interface between ECC and external system with json dataformat.I used a REST adapter in PI and completed the configuration. But when i send message from ECC,error occured.Error message in monitor was below:

use connection SOAP_http://sap.com/xi/XI/System transfer message error,because:com.sap.engine.interfaces.messaging.api.exception.MessagingException: 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.

The external system server provided a PKCS#12 Key Pair certificate and i imported it to the trustCAS:NWA->configuration->security->certificate and keys->TrustedCAS.I try the test again,but still failed with the same error message.Should i restart the PI server or is there any other configuration i have missed?
