Loading library error when invoking
Hi all !
I need a little help... I managed to develop a webservice library
called libConfigurationManagerWS.so
It contains server files generated with wsdl2jar, and is normally
dynamically linked at runtime with LD_LIBRARY_PATH.
The webservice provide a single method, that does nothing at all for
the moment.
2 questions :
- Does libaxiscpp_mod.so load webservice dependencies (e.g : other
libs) from LD_LIBRARY_PATH or the webservice must be linked using "-l"
compiler option ?
- Seeing logs from server part, i can't guess anything about thius
issue. The only thing I see is
[08/03/2006 15:33:51:698 MET] 1 HandlerLoader > loadLib e7ad0
[000E7AFFFFFFD000000000FFFFFFFEFFFFFFB65DFFFFFFE400000000FFFFFFFEFFFFFFB664FFFFFFB000000000]

[000E7AFFFFFFD000000000FFFFFFFF251C1C000000010000000000000000]

[08/03/2006 15:33:51:702 MET] 1 AxisEngineException >

loading failed"
[08/03/2006 15:33:51:703 MET] 1 AxisEngineException <
AxisEngineException @ff0da988
( If I intentionally link my webservice lib with -l options, and
forget one depency, I have an explicit error telling me that there
were some unresolved symbols. )
How can I get more details about dlopen failures ?
Thanks in advance !

Hum, ok, my fault ;-)
Sorry for this mail, I just forgot to include the XService.cpp file,
the one which declares extern functions :p
But it reveals one thing : Axis traces should more explicit. If you do
a normal dlopen() then a dlsym(), it gives an explicit error, why not
leaving it in logs ?
