Problem

Connecting to Weblogic JMS queues that require SSL and the following error appears in the te.log:

Caused by: java.net.ConnectException: t3s://host1.com,host2.com,host3.com,host4.com:8002: Destination 10.245.55.173, 8002 unreachable.; nested exception is:
javax.net.ssl.SSLHandshakeException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target; No available router to destination.;

Resolution

Imported the Root certificate (and sometimes the Intermediate certificate) into the CACerts keystore (located at Axway/jre/lib/security/cacerts) in each B2Bi node.

To import the certificates, run the command “./keytool -import -alias WebLogic -keystore <Path to CACERTS> -file <Path to Certificate>”.
