jar to unpack a file

[John]

Hi there,

From time to time, I receive a updated Jar file and try to unpack it
at the same location by using the normal unpack command:
"
jar -xvf abc.jar
"

But sometimes it fails for the reason that some existing files can not
be over-written. That file is locked somehow. And because of that, the
"unpacking" is failed

My question is: if such thing happens, is there a EASY way that I can
ignore such errors and continue to unpack the rest of files ?


Thanks everyone and happy holidays !

The jar utility is no so advanced. But try with a unzip tool
(a jar file is a zip file).

Thank Arne,
I just did what you said, and it works perfectly. Should have thought
about that way.


Thank you and have a good one!

You can unpack it with the jar or zip API. Then you can recover from
errors.

See the code in the Replicator that unpacks zips.
