OracleJSP error: java.io.FileNotFoundException when submitting form

Question

I auto-generated a task form for a very simple test and receive this error when SUBMIT-ing the form.
OracleJSP error: java.io.FileNotFoundException:
Set the init-param debug_mode to "true" to see the complete exception message
I am guessing it has something to do with the generated ADF task flow?
Details of the test:
BPM 11.1.1.4
Process: none start > Initiator user task > none end
Data: process data object based on BO based on a (simple) complex type xsd
User is Weblogic, assigned to the single process role.
That's it. The form accepts the data entry (I confirmed this previously by adding a file writer). It just generates the error in the form's pop-up window.

Answer 1

Below is the file Empty1.jspx that you need -- (put it into public_html). No idea why it is needed, but removing it from the unbounded flow does not work. Hope this helps others.
