'Java' fork information
Hello,
You may already know that the process command line is limited according to the
OS. And that limit on Windows with the Win32 API CreateProcess is 32 Kb. If
the limit is exceeded, you get a java.io.IOException.
I just discovered that there is another limit: an argument of a command line
must not exceed a specific length.
On my Linux 2.6, that limit is 4075 - reasonnable I would say.
With jdk 1.4.1_05 on Windows 2000, that limit is 392...
It seems to be a JVM bug, as far as Win32 CreateProcess method works if an
argument is longer that 392.
What is really annoying: when the limit is exceeded, the Runtime.exec method
never returns: the JVM process sleeps for ever and no child comes up ?!?
Hope this helps on day

tar directory with ant
Posted by Yves Leung-Tack <yv...@laposte.net>.
Hi,
I'm using the tar task of ant but I come with a "problem" when
untaring the tared files.
I can make it work but not exaclty the way I want.
After taring directory basedir, see above, I untar it but I want to
keep the tar program to untar in
the directory basedir.
For example:
basedir
file1
file2
subdir1
subsubdir1
subsubdir2
Now when I untar the files tared by ant, it extract it to the current
directory ant not in basedir.
Is there a way to tell ant's tar to remember the basedir ?
Thanks
