Hello everyone,
I am using jar to consolidate a large number of files for transfer, about 2500.
The jar command seems to work fine and it says ....adding.... files while it is building the archive. If I capture the messages to a log the log has 2500 lines each of them says I file was addedd compression info etc.
Yet when I jar -x the archive file I only re-genereate 489 files of the original 2500.
Is there a limitations on the jar command, or any of the flags I should be setting for it really to contain all the files in itself?
Please let me know.
Thanks.

is the jar file > 4GB? There used to be a bug relating to filesize and 32 bit file pointers.

what does

Code:

jar -t filename.jar | wc -l

give you .... 2500?

When I do the jar -tvf file I get a list of 486 entries, which is what I am able to get if I extract out from the file using jar -x.
Yet at time of creation via jar command a log file containing 2500 lines told me that all of the files went though with the ...adding..... deflate info.
Any idea?
Thanks!

The file size is not that large, less than 1Gig

Just one more piece to this puzzle ....even if the log of the jar creation contains the whole 2500 files listed one at a time, what is getting listed when I run the jar -tvf of the created file are only the last 486 of the 2500. Any reason why this would begin to make sense?
