File not found (WFMLRSVCApp.ear) during Oracle 11g release 2 installation

A friend called yesterday evening, sad and worried. He was trying to install the new Oracle Database - 11g Release 2 - but got stuck. He kept getting the a "File not found" error during installation, and couldn't find where did he go wrong.



He followed me through his steps - He downloaded the installation zip files. He verified that they downloaded ok. He unzipped each one into a designated folder. Then he  followed all the pre-installation prerequisites like a good DBA. And yet, that horrible error message kept appearing, and he could find no where online why this happened to him....

Between the lines I could understand that the best part of his Saturday has been spent in repeating attempts to find why WFMLRSVCApp.ear was missing.

As I've had this dubious experience myself in the past, the solution was easy. In the past, Oracle installations that spanned several CD-ROMs were asking during installation for the next CD. During the passage to the age of downloading it all from the web things changed. Although the instructions on Oracle's website clearly state: "Download and unzip both files to the same directory" they are sometimes missed.

All he had to do was move all the files under \file-number-2-extraction-folder\database\stage\Components into the parallel ..\database\stage\Components underneath the first zip extraction folder, re-run the installation (after wiping away the left-overs from his failed installations) and the installation worked smoothly.
