copying files from jar file to a filesystem

[craftereric]

I have a jar file that contains directories and files. I need to copy
those directories and files to specified locations on a UNIX and
Windows file system. So directory A in the jar will be copied to C:/
Temp on Windows and /tmp in Unix. Is there any sample code that will
get me started? I guess I should use some sort of config file to
specify the source and destination directories.

The jar file has a structure like

A/
A/file1.txt
A/file2.txt

B/
B/file3.txt
B/file3.txt

Temp on Windows and /tmp in Unix. Is there any sample code that will
get me started

look at the class com.mindprod.replicator.FetchZips

It downloads zips and unpacks them.

Thanks for the reply. I looked at FetchZips but I don't think it will
meet my needs. I could package my directories/files in a zip instead
of a jar but I need to be able to copy certain directories to one
location and other files to another location based on the file/
directory name.

Are there other things I can try?

To expand on what I need the code to do:
For each directory or file in the archive, I need to process it. For
example, the file B/file3.txt would need to be copied to /var/tmp/
file.txt on a Unix machine and C:\Temp\LocalDir on a windows machine.
The entire directory A would need to be copied to /etc/ on Unix and C:
\Program Files\MyDir on Windows

A jar is a zip.

but I need to be able to copy certain directories to one
location and other files to another location based on the file/
directory name.

Write the code to do it. It is trivial.

Read the API documentation.

I did not intend for you to use FetchZips unmodified. It was to show
you how to use the low-level zip manipulating tools.

Sounds like you need to read up on File.list and FilenameFilters.

You can use the Zip methods to unpack jars. Jars are just zips with a
few magic members.
