oracle.adf.view.faces.bi.webapp.MapProxyServlet not found…
I cannot give you guys an exact fix for this, but what I did
to make the application run, it works
So in my application, I went to my Project Properties
Clicked on Deployment, selected the Deployment plan, and clicked edit.
Click on edit, and then go to the File Groups -> WEB-INF/lib
-> Contributors
Then I selected all the ADF Libraries that were not selected
in the application by default and clicked ok.
Once that was completed I redeployed the application with no errors.
