SOLUTION:

This error seems to be compatibility issue.
As per compatibility matrix, Oracle Webgate 11.1.2.3 is not compatible with Oracle HTTP Server(OHS) 11.1.1.7
For Oracle Webgate 11.1.2.3,please install Oracle HTTP Server(OHS) 11.1.1.9.
Once OHS 11.1.1.9 is installed/configured, above issue/error will be resolved.

Note:
Before installing / configuring any Oracle Access Manager product,please check compatibility matrix for all Oracle products i.e(Oracle Access Manager,Oracle HTTP server,Oracle Webgate and Java Version)
