What exactly are you trying to do?  Write the output of a Cocoon
pipeline into request/session attributes then forward the request to a
JSP that contains these tags?  Have a Cocoon pipeline dynamically
generate a JSP that contains these tags, which is subsequently run by
the container's JSP processor?  Use Cocoon's JSP generator to call a
JSP that uses these tags, then pass the resulting output through the
rest of a pipeline?  Or something else entirely?

Since you talk about outputting a taglib directive, it sounds to me
like you're trying to dynamically generate a JSP using a Cocoon
pipeline.  Even if you could get it to work, this is probably a bad
idea - every matching request would run a pipeline, call the JSP
Compiler, run the resulting servlet, ...
Not particularly efficient, and depending on what app server you're
using it may be prone to memory or file handle leaks.  If you can give
us a better idea what you're trying to achieve we may be able to
suggest a better way to do it.  At the moment it just sounds to me
like you need to make your mind up which view technology you want to
use, Cocoon or JSPs.
