Customizing Applications with MDS

Question

I have been investigating static customization using MDS and have read through [Customizing Applications with MDS|http://download.oracle.com/docs/cd/E12839_01/web.1111/b31974/customize.htm] (and the seemingly identical copy in JDeveloper's Help Center). However, I have been unable to customize my application because I get this error (some parts have been abbreviated) when starting JDeveloper with the Customization Developer Role:
Error initializing MDS configuration for application "file:/C:/Documents and Settings/..._adf_main.jws". Customizations disabled for this application. MDS-00035: cannot load the class: oracle....uiview.IndustryCC.
The problem is that I do not know how to add the particular class to JDeveloper's classpath as instructed in section 33.2.1.4 of the documentation. I have added my class to JDeveloper's classpath via dropping a .jar into lib/ext of the JRE but then had horrible dependency troubles.
While walking through the documentation, I discovered that Example 33-1 and its surrounding documentation are out-of-date because getIDPrefix() is final in CustomizationClass and thus cannot be overridden as the documentation instructs.
I am using JDeveloper Version 11.1.1.1.0 Build JDEVADF_11.1.1.1.0_GENERIC_090421.1521.5361.
How do I successfully enter customization mode for my application?

Thank you. I got it working.
All I needed was the path provided at Create and Deploy a Customization Class, item 7.
I will note that the documentation does not have any slashes in its path:
<JDEVELOPER_HOME>jdeveloperjdevlibpatches<jar_file_name>
I got it to work after I copied the jar file I had already prepared to:
<JDEVELOPER_HOME>/jdeveloper/jdev/lib/patches/<jar_file_name>
