I can't remember exactly how the TagExtraInfo stuff works but have a look at the compiled jsp (the .java src file) in tomcat's work directory. It may have created a variable EditorContent of type boa.EditorContent for you to reference.
The pageContext variable in the above code is an implicit object available in the jsp and is the same object you used in the tag. See section 2.8.3 of the JSP 1.2 spec for details: http://java.sun.com/products/jsp/download.html#specs

Can you show us the errors that were reported when the JSP failed to compile? Full stacktraces are best.

Yes, here they are. I guess my real problem is that I'm not sure how to reference the object from the page. All the errors and source code are below. Thanks.
