发帖数: 3271 | 4 An entry is a file or folder in a zip file. Seems it is impossible to append,
modify or delete the content of a zip except create a new copy of the whole
file.

发帖数: 1685 | 7 I think winzip uncompress file and compress them back.
btw, jar can be compressed or uncompressed, compressed format is just zip,
(some software might create weird zip), you can associate .jar with winzip,
or rename the file to .zip.

发帖数: 158 | 8 i'll take your word for it, and try to justify that it's not so stupid.
however if it turns out that jar API does do it, then it's your fault:)
if you want to remove one node from an XML file, and you want to use the
'ellegantly designed user friendly' DOM/SAX API, you have to read the whole
thing, change the structure in memory/on the fly, and serialize it to a
new file.
so same thing here for jar. the API is designed to be source/target
agnostic, it does not (want to) concern itself with featu

Try,
1) winzip, if you are deleting an entry without programming;
2) java.util.zip

case) and I want to add or delete one file from it, I need to copy the whole
100mb content? That's ridiculous.

发帖数: 1685 | 13 try it with winzip, I saw the temp file created there.. with similar
size.. so if you want to do that on a 100mb zip, winzip would do such
stupid thing for you. it's ridiculous but I am not kidding.

发帖数: 3271 | 14 Both of your points doesnot make since. At least up to JDK1.4.2, it is
impossible using java.util.zip. I am not kidding, probably my experience with
this package is much more than most people on this board.
