Re: [Wrapper-user] socket creation failed and libwrapper.so

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

Nicolas,
    Thanks for the detailed report.  I do not have access to an HP-UX 
machine but
others have been using  it on that platform without problems as far as I 
know.
If any HP-UX users out there could chime in, I would appreciate it.

    Problem 1:  The library not being loaded.  Looking at the ls and 
wrapper.log
output that you provided, the only ideas that I have here are permission 
problems
reading the file or maybe that the library file is corrupted.  In the 
wrapper.jar file
that I am sending you, I have added code to test for this case.  This 
will be in the
3.0.2 release as well.

    Problem 2:  Socket disconnect problem.   This one is puzzling.   The 
Java side
successfully connects to the native code and sends back the 
authorization key.
The Wrapper then responds by sending the Log Level to the JVM.  The JVM is
successfully reading this Log Level and displaying a message.  The 
problem is
that at this point, it appears that the JVM is closing the socket for 
some reason.
    Looking at the code, the only thing that I can find that would cause 
this is if an
IOException was being thrown.  I am currently not displaying this stack 
trace
because up until now, it is only thrown in the event of the socket being 
closed on
shutdown.   This may not be correct.   I have temporarily added some 
stack dumps
to the code and have build you a special wrapper.jar file to test this. 
  (I will send it
to you directly as everyone else on the list does not need it.  Please 
respond to
the list though.)   If you could send me the new wrapper.log just as you 
did this
time, it might give me the info I need to get this fixed for you.  I 
only need a single
run of the Wrapper output. You don't need to send all 5 attempts at 
launching the
JVM.

Cheers,
Leif
