Error when upgrading Oracle from 10.2.0.4 to 11.2.0.2

Question

Hello All,
I am running the OUI to for the Oracle database 11g Release 2 Installer (AIX 64bit.) and I am getting the error message "File not found :/oracle/NWD/112_64/oc4j/j2ee/oc4j_applications/applications/WFMLRSVCApp.ear".
I don't know why the file is missing or where to get the missing file from?
These is summary(global settings):
Disk Space: required 7.44gb, available 13.71gb
Source Location: /oracle/stage/112_64/database/install../stage/products.xms
Database Edition: Enterpirse Edition (Install database software only)
Oracle base: /oracle
Software location: /oracle/NWD/112_64
Provileged operation system groups: dba(OSDBA), oper (OSOPER)
*And the installer fails with this error message:*
*File not found*
*/oracle/NWD/112_64/owb/external/oc4j_applications/applications/WFMLRSVCApp.ear
These are the (/oracle/oraInventory/logs) installtion logs:

I am Installing the Current Patch Set for 11.2.0.2
I read the README.txt file for the Opatch and I have JDK.
I have unzipped the OPatch_11201_Generic_v3.zip file to oracle/<DBSID>/112_64/ and when I try to apply it, I get the below error:

Any ideas? Am I missing something?
