What do you want?

There's a scene in Field of Dreams where Kevin Costner
has taken James Earl Jones to Fenway park to see a baseball game. As
they stand in line at a food concession, Costner asks Jones, "what do
you want?" Jones rails against fans that have hounded him for decades
and says that he just wants to be left alone. "No, " Kostner says
gesturing at the concession stand, "what do you want?" Jones answers
that he'd like a "dog and a beer."

So we've heard from Chet Haase and now from Peter Delisle asking
what you want for this year's JavaOne. You can keep quiet. You can
answer them and rail against injustices from past years. Or, you can
tell them what you want.

Give them a chance to do the right thing. Tell them what you want
for this year's JavaOne (we'll soon be launching a forum to help you
do just that). For now, take a moment when Peter blogs href="">No

Forums. What do you think of lucretious2's post that
"Someone suggested the following good idea (or this is my version of
it anyway):instead ofa.equals(b)you can write

equals b
Similary for any method call with a single
parameter:a = b add c; // b.add(c) This is a kind of a
lite form of operator overloading."

What about href="">

in Java Today
, Andrei Cioroianu writes "Content caching is
one of the most common optimization techniques used in web
applications, and it can be implemented easily. For example, you can
use a custom JSP tag — let's call
it <jc:cache> — to wrap every page fragment
that must be cached between <jc:cache>
and </jc:cache>. Any custom tag can control when
its body (i.e. the wrapped page fragment) is executed, and the dynamic
output can be captured. The <jc:cache> tag lets the
JSP container (e.g. Tomcat) generate the content only once, storing
each cached fragment as a JSP variable in the application scope. Every
time the JSP page is executed, the custom tag inserts the cached page
fragment without re-executing the JSP code that generated the output."
In href="">Caching
Dynamic Content with JSP 2.0, he takes this a step further,
allowing the cached content to be customized for each request or each

Eric Giguere explains href="">
Game Canvas Basics in a recent Core Wireless Tech
Tip. The GameCanvas class extends Canvas
which "gives the application no control over when a canvas repaints
itself - all it can do is request a repaint - or over how quickly key
and pointer events get delivered to the canvas. This lack of control
can cause action games and others that are speed-sensitive to feel
sluggish and unresponsive. GameCanvas was designed specifically to fix
these weak points."
