JSP vs Velocity
I like Velocity. However, there are lots of JSP tags, such as JSP output stream buffer cache tag I could use, I had hard time to find similiar Velocity library.
Which do you prefer? Any serious JetSpeed Velocity development and deployment?
How is the popularity of JetSpeed?

They can be either Velocity or JSP.

Yes, with JspPortlet, you would use request attributes which is equivalent
to Velocity "context".

But wondering the overall templates need to be still velocity in jetspeed
framework.
the portlets can be jsp. remember that context object is always null in
jsp :-)

I would say that it works perfectly well for my strategy, but I believe
there's still an issue over how JSPs handle actions. I've been pushing that
one off, but I will eventually reach a point where I can't ignore it.
FWIW, my strategy is to prototype in JSP, then move the code into a class
that inherits from AbstractInstancePortlet. For the most part, my approach
has been to have that class generate what amounts to a List of objects
which are placed into the request. The JSP is then limited to iterating
through the list and simply displaying the getXXX attributes of each object.
My JSP files are nothing more than iterators, and this works pretty well for
me. If this is a radically incorrect approach, I'd appreciate the feedback
now!!!
Once you reach this level of isolation, it really doesn't matter if you
choose JSP or Velocity. My rational behind choosing JSPs is as follows:
1) Its faster (for me, but YMMV) to prototype my Java code in JSPs
2) Dreamweaver understands JSPs
3) If I need to contract out, JSP-savvy designers are far more common (and
hence cheaper) than Velocity-savvy ones
4) Thus far, I have the CPU cycles to spare on JSP, though this may change
once I go live

How so? No, I'm not trying to start a Velocity vs. JSP war but I'm
interested in any shortcomings with the JSP integration.

I suggest you will find that Velocity performs better in Jetspeed.
Furthermore, you'll find that JSP's integration is largely a kludge. I
would suggest that JSP is not appropriate for outputting binary files.
