I figured it out, here is the reason.1) All system class paths to the jars
NEED to be replicated in the coldfusion JVM class paths.
2) all jars which to with the above coldfusion class paths are created NEED
to be located in the wwwroot\WEB-INF\lib directory. coldfusion cannot find
them from anywhere else.
feels good after pulling my hair out for a couple of days.
