Hello group. New to ruby and needing the ability to unzip EAR files.  
Isn’t  
an EAR file technically just a zip file? I’ve been able to untar  
tarballs  
and unzip zip files in Ruby but failed for ear files. Any pointers  
appreciated.

Error msg: bad value for range

def unzip(zipfile, dest)  
zf = Zip::ZipFile.open(zipfile)  
zf.each do |entry|  
begin  
file=file\_to\_basename(entry)  
File.makedirs("#{dest}/#{file}") unless File.exists?  
“#{dest}/#{file}”  
zf.extract(entry, “#{dest}/#{entry.name}”)  
rescue Exception =\> e  
log(“Error while unzipping: #{dest}/#{file}: #{e}”, 1)  
end  
end  
end

pete@dello:~$ file metasearch.war  
metasearch.war: Zip archive data, at least v1.0 to extract

I have never used unzip from Ruby for WAR/EAR files though - I am really  
curious now why should it not work?

Yes, it is a strange one…It looks like it starts to unarchive the  
files but  
it chokes while extracting a war file from the ear.

from unzip in ruby:

path: ./tmp/ADT110\_1.1.0.2/ADT/Install/ADT.ear  
Error while unzipping: ADTWeb.war : bad value for range

system unzip shows the ADTWeb.war that fails in the ruby zip lib.

[ccyphers@ccyphers Install]$ unzip ADT.ear  
Archive: ADT.ear
