Hi,
thanks for all the replies to my original posting, I see a little bit
clearer now. So, beans are just a means to more distinctly separate java
code from code on the JSP page. But I think this only makes real sense
if it is carried out to the full extent, i.e. if custom tag libs are
used to banish java code from the page, otherwise it's a half hearted
approach.
