Re: [Wrapper-user] Two wrapper.log files ...

[Leif M. <le...@ta...>]

Yasir,
    If the Wrapper encounters an error before it has learned where it is 
supposed to
write its log file it defaults to writing to a file called wrapper.log 
in the same directory
as the wrapper binary.

    In this case, the Wrapper is having problems expanding your CLASSPATH
environment variable because doing so would lead to a buffer overflow.   The
Wrapper currently only allows expanded environment variables to be 16384
bytes long.   That seemed like it would be plenty large at the time.  I 
guess that
proved wrong.   I don't want to make it any bigger as it just wastes 
memory for
most users.   I'll have to do some dynamic allocation of the buffer so 
it will meet
the needs of any user.

    For now though it is just a warning.  You will not be able to 
reference the
CLASSPATH environment variable in your wrapper.conf file.  But the Wrapper
should work just fine.

    I posted a feature request so I remember to get this fixed:
http://sourceforge.net/tracker/index.php?func=detail&aid=827659&group_id=39428&atid=425190

    To get rid of this warning, you will have to shorten that CLASSPATH 
a bit.

    Let me know if you have any other questions / concerns.

    Cheers,
    Leif
