1. Check out the Simple Content Portlet from Jasig Subversion:

$ svn co https://source.jasig.org/portlets/SimpleContentPortlet/trunk SimpleContentPortlet

2. Build the portlet using maven.

$ cd SimpleContentPortlet
$ mvn clean install

In uPortal, this step involves calling the portal's deployPortletApp ant task from the command line. From uPortal's top-level directory:

$ ant deployPortletApp -DportletApp=/path/to/SimpleContentPortlet/target/SimpleContentPortlet.war

...

AntiSamy may be disabled via a simple portlet preference called "cleanContent". To disable content scanning, simply set "cleanContent" to "false". A sample alternate "Advanced CMS" configuration with content scanning disabled is included at the bottom of the distributed portlet.xml file.

CKEDITOR configuration

In addition to AntiSamy, the editor used (CKEDITOR) does its own filtering and transformation.  To disable CKEDITOR' content filtering and rely only on AntiSamy, modify WEB-INF/jsp/configureContent.jsp to have 

allowedContent: true;
