ANT and Winzip problem

[Alex Givant]

Hi, All!
I've got the problem: When I create .zip file with Ant's "zip" task, I can't open it with Winzip 6.2 (it opens all file with 0 byte length). If I try Winzip 8.0 or WinRar, everything is OK.
Does anybody have the same problem and what you did to solve it.
Thank you in advance.
Alex Givant.

I have never had this issue come up, but I seem to recall some sort of zip format change.
I use jar all the time to zip up and unzip things. Maybe that will work for you?

Thank you for response, but we need to produce distribution in ZIP format, which will be used by QA and customer.
Any other thoughts?

The jar, war, ear, and zip tasks all are using a common base to build the files - so building a zip file with the jar task is acceptable, it only depends on what other features you need. For example, the war task has built-in capability to place files in the WEB-INF directory.

I havent heard of this problem before, perhaps you should file it with ants bug system, on nagoya.apache.org. I think it may just be that winzip6.2 is too old to handle the long filenames or other changes to the zip format...winzip 7 works nicely with ant generated zips.
remember that the jar command in the JDK can also unzip a file (jar xvf filename.zip) so anyone with a JDK has a standardised unzipper to hand.
