JSP-Tags: bodyContent == null in doAfterBody() in TomCat, not in iPlanet

Hi there
I have a small TagLib Library in developed in iPlanet 6 with java 1.2.2.
There it's working well.
Now a wanted to migrate to Tomcat 4.1.12, Apache HTTP Server 2.0.40,
mod_jk2, J2SDK 1.4.1, Win2000 (for testing, Solaris later)
But there, in the doAfterBody() method of the JSP-Tag I can't get the
bodyContent.
Where the bug? In Tomcat or in me?
Thanks for every hint
  Braini
