Re: Why "java.util.zip.ZipOutputStream" need to use /tmp?

["Oliver B. Fischer" <o....@swe-blog.net>]

Hello Steve,

I assume what the java.io.FileOutputStream uses /tmp as tempdir. As you
can see, the errors occurs in a native method. As far I know, /tmp is
standard temp directory on UNIX systems automatically used by many
native library calls. May you can set $TEMPDIR
(http://en.wikipedia.org/wiki/TMPDIR) to another directory?

Best regards,

Oliver
