       Body:
I have been trying my best to get the threads working with the pseudo 
thread model of LibWWW. But even with lib level init within Axis C++, when used with a real pthrerad application, the LibWWW
library fails. Looks like we have to modify LibWWW to make it really 
thread safe (putting locks etc.) - see http://lists.w3.org/Archives/Public/www-lib/1998JanMar/0033.html for more details (looking at the mail threads on thread safety of LibWWW mail list archives, it looks like many have unresolved problems with LibWWW thread safety. 
It is too much to include thread safe locks in LibWWW code and use it in Axis C++. I do not think it is worth consodering to use LibWWW based transport with our own modifications to LibWWW source, to make it thread safe.

        Key: AXISCPP-180
    Summary: Make the LibWWW based transport thread safe
       Type: Bug

     Status: Open
   Priority: Major

    Project: Axis-C++
 Components: 
             Transport (Server)
   Versions:
             current (nightly)

Environment: Linux platfrom

Description:
The test program in tests/client/threadSafe fails randomly with LibWWW based transport.
It was expected that lib level init made possible by Axis::initialize would have made this transport thread safe, however, there are some undefined behaviours at times.
This problem could not be solved even with the pseudo locking model implemented to guard against event loop conflicts.
