SOLUTION:

vi $ORACLE_HOME/j2ee/OC4J_Portal/applications/portalTools/omniPortlet/WEB-INF/web.xml

# Fix the following context parameters to ensure that HTTP is used and not HTTPS that is used by the site:

<context-param> 
    <param-name>useScheme<param-name>
                         ^^^^^^^^^^^^
                         ---------------> WRONG should be </param-name>
    <param-value>HTTP</param-value>
</context-param>
<context-param>
    <param-name>usePort</param-name>
    <param-value>7777</param-value>
</context-param>

## CORRECTED SETTING:

<context-param> 
    <param-name>useScheme</param-name>
    <param-value>HTTP</param-value>
</context-param>
<context-param>
    <param-name>usePort</param-name>
    <param-value>7777</param-value>
</context-param>


There is a TYPO in Oracle's Configure Seeded Providers and Provider Groups instructions (as of FEB-20-2007) it reads:

   <context-param> 
       <param-name>useScheme<param-name>  <==== WRONG should be <param-name>useScheme</param-name>
       <param-value>HTTP</param-value>
   </context-param>
   <context-param>
       <param-name>usePort</param-name>
       <param-value>7777</param-value>
   </context-param>
