Pack200
I though with the java.net project that Pack200 would be included in ANT
1.7. Is this planned for a future release?
I have an implementation that I modified from somewhere to work like a
fileset. I have not spent too much time developing ANT tasks, and so it
might need to be cleanup up a bit, but I would be happy to submit it
somewhere if there is interest.

The pack200 ant task code
(https://java-pack200-ant-task.dev.java.net/) is licensed
using the "SUN PUBLIC LICENSE"
(http://www.netbeans.org/about/legal/spl.html) and thus not suitable
for including in
ant source.
That been said, the code is a very thin wrapper java.util.jar.Pack200.Pack200.
So, write your our wrapper, create a bugzilla report with the code
testcases and doc attached.

Well, I don't think it will be too difficult, and there certainly are a lot
of core ant tasks I can pull information from. So, if I get bored sometime,
maybe I will give it a whirl. I could still use it, even if no one else
does. :)
Thanks for the advice.

no, its more 'we dont know what is happening there well enough to take a
guess".
If they do pack200 exe with 100% compatibility with sun-pack200, life is
simple.
If they do something low level, we are in the multiple-facade-pattern which
we do for javac and the like and which is unduly complex. the other risk is
that sun pull pack200 in java6 or later. Assuming that they keep everything
stable there, we can do a task, but we cannot use any of the code from the
java.net . Instead we need
-good dependency logic
-error messages for end users
-some tests.

PININ' for the FJORDS?!?!?!? What kind of talk is that?, look, why did he
fall flat on his back the moment I got 'im home?
...'E's kicked the bucket, 'e's shuffled off 'is mortal coil, run down the
curtain and joined the bleedin' choir invisibile!!
THIS IS AN EX-PROJECT!!
I always appreciate a bit a levity.

So, the Harmony project will follow the specifications of the pack200
format, but not necessarily the interface (options as so on)? Not that you
have any control over it, but that seems like a poor decision. I hope it is
similar enough so that people aren't forced into a decision about which to
use, Harmony or Sun's JRE. (That's is my 2 cents.)
Anyway, to me it sounds like you are saying that ANT is currently not
interested in a pack200 task until the Harmony project has decided on its
implementation? Is this a fair assessment of what you said?

1. I checked, yes, the deployment.java.net project is, if not dead, pining
for the fjords.
2. Harmony is adding pack200 support too.
any apache ant task would want to work with the Harmony impl, alongside the
sun one, or we go with the harmony one only as a complete redist that may
even work on java1.4 systems. in which case the ant project itself probably
isnt the right place for it, as it is coupled more tightly to the harmony
API

Well, be that as it may, I feel that having a pack200 task would be a great
feature. We distribute our code via webstart and the pack200 format really
does do a great job compressing jar files.
The code I got from java.net did not quite work for me and I had to modify
it quite a bit. I submitted my modifications back to the project where the
originals from, but then it didn't go anywhere. In fact, I can't even find
the posts I sent with my modifications. Maybe this is because the java.net
project (https://java-pack200-ant-task.dev.java.net/) says its defunct.
In any case, is there anything that I can do to get this ball rolling? I
don't want to step on any toes, or break any copyrights, but I certainly
feel that the pack200 should be a part of core ANT.

AFAIK the people developing the tasks at java.net have never approached us -
and we certainly don't walk around assimilating other people's code without
asking them.
