Thanks for the response. This was pretty much the same conclusion
I came to, but I just wanted to make sure I wasn't missing something.
It took me a few days of spec reading to determine that the only
real similiarity between JavaBeans and Enterprise JavaBeans is
that they are both components, with completely different characteristics
(one for client side app development and the other for server-side
development).

This is basically what I was asking, i.e., are there any EJB-specific
options available with the <usebean:> tag to make things simpler for
JSP developers who want to access EJBs. I realize it's not rocket science
to locate an EJB via JNDI, but it seems to me that this causes the JSP to get
'cluttered' with some repeated boiler-plate code that could be hidden via
a <usebean> (or maybe <useEJB>???) tag. Sounds like this is still TBD
from what you're saying.
