Certifcate Problem REST Adapter (SSL-Security)

[openrico]

Hello SAP-Professionals,

I have a Problem with my REST-Adapter (Receiver Adapter) using SSL-Security.

I've imported the Receiver Certificate into the NetWeaver Administrator.

Now i defined the certificate as a specific client certificate in the Rest Communication Channel.

Unfortunately i get the following error:

sun.security.validator.ValidatorException: PKIX path building failed sun.security.Provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Am I doing something wrong or did I skip an important step?

I hope you can help me to solve my problem.

Thank you.

Kind Regards,

Enrico

Hi Enrico

You have only imported the client certificate which is used for the server to authenticate your PI system.

The error you are getting is likely due to missing Root CA certificate for the server, which is used by your PI system to authenticate the server. Get the target server's Root CA certificate and import it into TrustedCA keystore in NWA. For more details, you can also refer to my blog below:-

Enrico,

Please try importing the client certificate in the TrustedCA keystore.
