Webdavlib.jar --- file name too long exception

Hi,

I am using Webdavlib.jar to download files. When a file path is very long, I
got this:

     [java] Message:

The webdavlib.jar API tries to write a tmp file on disk and find the file
nams is too long.  I think to generate that kind of tmp file path could be
replaced by other ways to avoid this problem.

Re: Webdavlib.jar --- file name too long exception

Posted by Sung-Gu <jericho at apache.org>.

To prevent your problem, probably, we need the file name to be shorted by the hash function...
We have to read and write the hash-named file, and after any reading or writing, I guess...  

Currenly, the temporary directory and file is readable, because it has time and a saving directory information.
So before any better ideas, I will JUST set the length for file name LOWER temporarily...
