Check your web.xml within your WAR, there is a servlet and servlet-mapping for the Oracle help files and this servlet most likely.

Comment out those.

I received the same error as "failed to preload on startup in Web application:".

Below is how I am able to resolve the error.

in your web.xml, check if following property is present

<load-on-startup>0</load-on-startup>

this property is to load your bundled artifacts during the server restart itself. This was the cause of the issue because there were some jar file which weblogic server required to load before the loading of our bundled artifacts. Now since server is not yet started completely and all the libraries required to our application is not yet loaded, hence server is throwing "failed to preload on startup in Web application:".

The solution to this is remove load-on-startup from web.xml and That's it!!
