Re: VFS how to read gzipped content from tar file

[Ken Tanaka]

Thanks for the suggestion, but I'm getting a different error when I try 
that:
org.apache.commons.vfs.FileSystemException: Could not resolve file 
"gz:tar:file:///extra/data/tryVfs/archive.tar!/!/".

Here is the exact code corresponding to the above error:
           FileObject contentFile = fsManager.resolveFile(
                   
"gz:tar:///extra/data/tryVfs/archive.tar!/tardir/content.txt.gz"
               );

Hi Ken,

Ken Tanaka a écrit :

   FileObject gzTarFile = 
fsManager.resolveFile("tar:gz:/archive.tar!/tardir/content.txt.gz");

try this :

fsManager.resolveFile("gz:tar:/archive.tar!/tardir/content.txt.gz");
