I asked this question a while back, and there is a pretty easy way to handle
this.
Search the archives for:   "exposing script variables".

You may want to retrieve an object (other than a string) in order to perform
an method from it, say for instance, a resultset.
Another possibility it that you would want to retrieve a string from the
request/session (or from a resource bundle)  that will need to be used in
other custom tags.  Since custom tag attributes cannot contain another custom
tag, the only method of passing these values around is through a script
variable.
