After installed new SHA2 certificate on Oracle Weblogic Server, SSL communication to WLS is failing. In this case, the OHS installed WLS Proxy Plugin is sending the request to WLS where the original request is originating from Oracle Forms / Reports use of the JRE client:
JRE Client --> HTTPS --> OHS/mod_wl_ohs --> HTTPS --> WLS
OHS log trace :

SSL communication between the OHS and the WLS should work with SHA2 certificates.
1) Upgraded JDK from 1.6 to 1.7
2) Installed new SHA2 certificate on WLS
