FxAll TCPI 4.2.0.1 Configuring Certificates

I am trying to configure the certificates for TCPI 4.2.0.1 I have placed all 3 certificate in location /etc/cert/fxall/. And I have set the property SSL_CA_CERTIFICATES_DIR as system property in my java command. But when I try to connect I have the following error.

javax.jms.JMSException: javax.net.ssl.SSLHandshakeException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target: ssl://<server>:<port>

Trying to find solution to the above issue and searching for documentation that explains the way to configure these certificated when running the tcpi application in linux.
