Solution

1. Navigate to Servers > AdminServer > Protocols and "Enable Tunneling"

2. Make this change to the envcode.properties file (or equivalent) when deploying (basically, use HTTP instead of T3):

OLD: osbAdminUrl=t3://192.168.0.30:7001

NEW: osbAdminUrl=http://192.168.0.30:7001

Applicable Versions

• Oracle WebLogic Server 11g (11.1.1.9.0)
• Oracle Service Bus (OSB) 11g (11.1.1.9.0)
