I have received the above error when deployed the ADF project in to the WebLogic server. The reason to the error is it is missing the jar file ‘adfmweb-<version>.jar‘.

My adfmweb-12.2.1.0.0.jar file contain the missing class file

Solution1:

Instead of deploy ADF project, Deploy the whole application as an ear file.

Solution2:

Right click on the project >> Click Project properties >> Click the Deployment >> Select the Deployment Profile >> Click Edit >> Enable ADF Web Runtime as shown below >> Click Ok >> Okagain >>Deploy with the modified Deployment profile
