Accessing APEX from E-Business Suite 11.5.10

Question

Hi All -
I am brand new to APEX and have basically inherited the program duties b/c the school district that I work for had to cut costs and therefore had to let our consultants go - which means that I need to manage the system with no knowledge.....
that being said - I apologize in advance if I am very slow.
My first task is to see if we can set up the system where the users can access APEX straight from Oracle without having to login a separate time. I found this doc: http://www.oracle.com/technology/products/database/application_express/pdf/Extend_Oracle_Applications_11i.pdf
I tried to follow that but am sure I am missing something. Here is what I put in my pl/sql procedure:

Any help would be greatly appreciated!!
