As I have mentioned earlier that we would like to upgrade ourself from IDM 10.1.4.0.1 to IDM 10.1.4.2 as we had some issues with accessing Partner Applications Administration page. Although WNA works well with older version. We had major issue with WNA once we upgraded to IDM 10.1.4.2, it actually stops working and there are no workarounds as per Oracle Support, this is what they has to say
"Current versions of OID are only certified with the shipped JDK version.Certification for JDK version 1.4.2_18 and OID is expected to be available in future AS/OID 10.1.4.3.0 Patchset (not ETA available)."
So we have to revert back to same working old version 10.1.4.0.1 till we have official release of 10.1.4.3.0
Happy Troubleshooting !!!
