RE: AXIS (1.4) crashing on when deserialising result from SOAP-Se
rver
One way to get around this problem is to make your app and all it's
dependent DLLs use the same C-runtime (so they use the same heap). The
Xerces binary, at least the one I have, uses Debug Multithreaded DLL (debug
library), and Multithreaded DLL (release library). So if you recompile
AxisClient, Axis2Transport, AxisXMLParser, and your own app using the same
C-runtime things should be fine. The option is under
Project->Settings->C++->Code Generation->Use runtime library (in VC++ 6).
The VC++ projects in the Axis C++ distribution use a variety of C-runtimes.
Might be a good idea to change that.
Bruce.

Subject: RE: AXIS (1.4) crashing on when deserialising result from
SOAP-Server
I have had the same problem and I thought I had seen it reported but now
cannot find where. It's more a problem of Windows development generally
than anything specific to Axis. Memory is being allocated in Axis and the
deallocated in your application (say) and the two use different versions of
the C run time library. Therefore the deallocator cannot understand the
structure of the memory block - it misses the debug header it expects to
find - and complains that it is corrupt. The same problem can occur if you
just run Xerces-C without using Axis at all.
I've never found a single simple solution to the problem, if anyone has one
I'd be most grateful to hear it. If you use MFC you may find that removing
the definitions of new as DEBUG_NEW does the trick.
Regards
Tony Dodd
