============================================
Solution ==>

Below logs shows this is for an issue with the certificates being used. 
Caused by: java.io.IOException: javax.net.ssl.SSLException: SSL handshake failed: X509CertChainIncompleteErr
this is a http handshake error, and the root cause is: incomplete certificate chain.
Please follow below technical note in B2B 10g dealing with Security configuration:
B2B-TN026: OHS Setup, HTTPs, FTPs, Signing, Encryption & sFTP
http://www.oracle.com/technetwork/testcontent/b2b-tn-026-security-133755.pdf
Please setup carefully the OHS/HTTPS as per that document.
Second, Please make sure that certificate being used (in a wallet, in a keystore, or as a standalone X509 certificate) it must contain the whole certificate chain which means:
Certificate Authority (CA) pulic key, any Intermediate Certificate Authority public key, and certificate.
Remember, a CA releases a certificate for us, but when the CA provides us the certificate, it also provides us its public key (CA public key)+ any intermediate CA public key (if this is the case).
So, as a second action plan would be as below :
-> make sure that you imported in the SSL wallet the full chain for certificates
-> make sure that you imported in the SSL wallet the full chain for partner certificates
-> make sure that the certificate configured in B2B for host TP contain the full chain of certificates
-> make sure that the certificate configured in B2B for remote TP contain the full chain of certificates
