Velocity.evaluate() renders textual output to a Writer. For the
expression language to work, I need to resolve objects. I can't find
anything in the javadocs that might give me a hook.
Any suggestions?
I know, I need to wade through the code, but a few starting pointers
would help.
Thanks,
Jeff

Wow! As a both a Velocity enthusiast and JSTL junkie that sounds like
a really useful tag.
It doesn't sound that hard to me. Extract the expression, call
Velocity.evaluate, and set the request attribute. I guess you'd have
to set up the context with all the beans first.

Short version: I wish for a JSP custom tag that will effectively let me
use Velocity expressions instead of the anemic JSTL expressions.
Long version:
Velocity already has a custom JSP tag that lets me do this:
<vel:velocity>
#if(true) cool velocity stuff #end
</vel:velocity>
However, what I really really want is something that lets me use
velocity expressions the way I would use JSTL expressions. The most
important is this:
<vel:set var="foo" value="${cool.velocity(syntax)}" />
The inability of JSTL expressions to call arbitrary java methods results
in muchhacking and hair pulling. Velocity expressions rock. I want
them :-)
How hard would it be to make a <vel:set> tag? I looked around the APIs
but couldn't find anything helpful.
Thanks,
Jeff
