Question

Best tool to reduce size of Jar file ?

Asked by: sbader

We distribute a signed-applet to customers over a dial-up modem.  We want to minimize the size of the applet to reduce the download time.

I've done a cursory search and it looks like there are various jar reducers/optimizers -- but nothing has jumped out as a good, serious solution.

What tool or tool(s) are best for this?

You could probably do as well if not better by hand optimization.

What I used to do in the case of applet deployment, was to use agrassive obfuscation. It changes all names to 1-2 char and remove dead code.
It reduced for us an applet from 850k to less than 400k.
There are many obfuscation tools. I used DashOPro http://www.globalsoft.com.tw/English/productMain.html but this product is not free.

Hope that helps,
Gadio

Do a search for java obfuscator.

Ive used Retrologic in the past with varying degrees of success. The version I used had problems with reflection (for obvious reasons). It has a LGPL license.
Here's the link:
